Description Onyeibo Oku 2014-08-16 06:51:21 UTC
Description of problem:
dnf fails to download packages from ftp sites. Terminal messages show that dnf is busy retrying broken links and performing checksum comparisons.  The result is a lot of data being downloaded and discarded. Eventually dnf gives up on the task and exits.  One can manually pull the broken packages from a web-browser by substituting the "ftp://" prefix with "http://" (an indication that the resource exists).

Running the same task with yum further confirms an anomaly.  Yum finishes the depsolving slower but is able to finish the session.  Yum skips URLs that are broken after first trial and doesn't choke on checksum comparisons.  Something is definitely wrong somewhere.

Version-Release number of selected component (if applicable):
dnf-0.5.5-1.fc22.noarch

How reproducible:
Have persisted for several weeks

Steps to Reproduce:
1. run an update with dnf (try with a mobile broadband)
2. watch the terminal outputs
3.

Actual results:
http://fpaste.org/126000/
the retrials and checks are expensive.  Sometimes truncated versions of packages larger than 10MB are downloaded several times and discarded.

Expected results:
smooth URL resolutions (especially ftp links), skip unreliable servers (no expensive retrials).  Is there no way to perform checksum comparisons before actual downloads?

Including fpaste content here (since fpaste expires over time).

Comment 2 Martin Sourada 2014-08-16 22:27:00 UTC
I see this as well, even on university connection (high speed, high reliability). As I recall, I didn't use to see this several months ago, also, sometimes running DNF even fails to download the packages at all, while retrying (sometimes several times) immediately after fail makes the issue almost magically disappear, or at least not to fail completely... It also seems to be getting worse recently.

Comment 3 Martin Sourada 2014-08-16 22:28:25 UTC
Oh, looking at the bug data: I forgot to mention, I'm seeing this on F20, dnf-0.5.4-2.fc20.noarch.

Comment 4 Honza Silhan 2014-08-18 12:38:59 UTC
Hi, thanks for the report. Tomas, can you take a look, please? Feel free to change component back to dnf if you consider it as dnf issue.

Comment 5 Martin Sourada 2014-08-18 13:41:50 UTC
Another info: running 

dnf clean all 

before 

dnf upgrade/install 

seems to fix the issue, i.e. even when dnf upgrade spams the console with [MIRROR] error messages (repeatedly, even after running the same command again and again and again...), issuing the same command after dnf clean all makes the errors disappear, completely. I guess there might be some cache/metadata issue behind this behaviour.

Hope this helps.

Comment 6 Honza Silhan 2014-08-19 14:59:26 UTC
hmmm, can someone upload somewhere metadata from `/var/cache/dnf` with wrong checksums and then the correct ones after executing `dnf clean all`, please?

Comment 7 Juan Manuel Rodriguez 2014-08-22 18:45:47 UTC
Hi Jan, 

What files do you need?

I have had a similar but very different issue with dnf / librepo. 

Instead of dnf "wasting all the bandwidth", I've had it try at a mirror once, then give up entirely. The same process through yum completes successfully.

Comment 8 Onyeibo Oku 2014-08-25 01:40:46 UTC
(In reply to Jan Silhan from comment #6)
> hmmm, can someone upload somewhere metadata from `/var/cache/dnf` with wrong

I have archived metadata capturing the checksums for three consecutive times (each followed by 'dnf clean all').  The files are huge (totalling 335MB). I am on a restrictive bandwidth subsciption and attachment limit is 20MB.  Please advise on how to make them available

Comment 9 Honza Silhan 2014-08-26 08:43:07 UTC
Right, choose only one repo (the smallest) where downloads are failing and disable the rest. Archive dir /var/cache/dnf/<arch>/<fc>/<repo>/repodata/ and some downloaded package where checksum doesn't match. Then do that again after 'dnf clean all', please.

Comment 10 Ales Kozumplik 2014-09-08 08:25:06 UTC
I will look at this (the needinfo still stands).

Comment 11 Ales Kozumplik 2014-09-08 08:38:52 UTC
Martin, I think your particular case is that of bug 1121183. In this bug I will focus only on the original issue reported in comment 0.

Comment 12 Ales Kozumplik 2014-09-08 11:40:26 UTC
Onyeibo,

despite my best efforts (fedora rawhide, dnf-0.6.1, rawhide versions of curl and librepo, mobile internet connect) I am not able to reproduce, the packages are downloading fine. Can I ask you to try downloading some packages after cleaning up the cache, e.g.

$ dnf clean all
$ LIBREPO_DEBUG=True dnf download gdb* --enablerepo=rawhide &>out

and report if the problem is reproducible that way and attach the 'out' file?

Also, to be sure we're chasing a legit bug it would really help if bug 1121183 got fixed, setting a blocker.

Thanks!

Comment 13 Ales Kozumplik 2014-09-09 14:39:43 UTC
(I can confirm that fedora-repos-rawhide-22-0.1.noarch has bug 1121183 fixed.)

Comment 14 Ales Kozumplik 2014-09-10 07:58:51 UTC
(de-priortizing, apparently not as urgent as originally seemed)

Comment 15 Onyeibo Oku 2014-09-15 21:38:10 UTC
Is there still need for repodata samples?
I'm hoping its not necessary any longer -- 50MB to 70MB of upload is still a significant bandwidth expense on a metered network.

Comment 16 Ales Kozumplik 2014-09-16 06:21:04 UTC
It would help somewhat in debugging this. Let's start with the request from comment 12 please.

Comment 17 Onyeibo Oku 2014-09-17 02:38:11 UTC
I have not had this issue after reinstalling and updating my rawhide machine for some days now.  It would be chasing the wind to debug this under the current conditions.  I don't get those checksum errors anymore.

I also have a problem with the renaming of this request.  The same network worked flawlessly with yum (in that period). I cannot imagine the criteria for categorizing the network as "slow/unstable". 

If you still want to chase this, I have uploaded the repodata snapshots here:
http://bugs.onyeibo.fastmail.fm.user.fm/errors-rawhide-repodata.tar.xz
(that's with checksum errors)

http://bugs.onyeibo.fastmail.fm.user.fm/smooth-rawhide-repodata.tar.xz
(that's running without checksum errors)

Goodluck.

Comment 18 Ales Kozumplik 2014-09-17 04:47:17 UTC
OK, thank you for the reply. It could even be that one of the components *below* librepo was broken as rawhide rolls on rather wildly. Closing this as unreproducible, if the same problem appears again please supply the librepo debug output as described in comment 12.

Compared to other download/md issues this bug should still be considered special due to the fact that the problem persisted after cleaning all md as described in comment 8. And I changed the summary based on comment 1 statement that this is reproducible on mobile broadband.

Comment 22 lejeczek 2014-12-16 10:29:05 UTC
when I do rpm -Va almost every file has - digest (formerly MD5 sum) differs.
How is that even possible??
Another thing is on my second laptop - which is slightly different for it had upgrade from f20 to rawhide(f22) some months ago whereas this one had clean f22 installation - I don't see this problem. 
My concern is it might be worth letting kernel dev know, I get the feeling there might be something wrong with AMD new CPUs (HP EliteBook 745 G2 AMD A10 PRO-7350B R6, 10 Compute Cores 4C+6G).

Comment 23 lejeczek 2014-12-16 10:43:51 UTC
also partitions are encrypted where the problem occurred, I'm guessing and trying to see the differences between two systems.

Comment 24 lejeczek 2014-12-16 11:00:49 UTC
now, the weirdest bit, after rpm -Va I told gnome session to reboot, gnome asked back whether to install updates, I said yes, rebooted, and updates installation started before Xwindows/gdm and it all went in fine! So it appears.
Will have to wait till new updates to see if it was one-off.

Comment 25 Tomas Mlcoch 2014-12-18 12:39:29 UTC
Hi lejeczek,
firstly thanks for the report with log attached!

This is very interesting because the error message says that expected checksum for "gcc-4.9.2-2.fc22.x86_64.rpm" was:
50e845c5f3c0a46a5f47ac1f393126565ef0ff62094cc650c5942e4bcedc7638 (sha256)

But I downloaded the file from the mirror and I got:
6bfe4cfecf13ab4a83d8b4a8d56482d39811c297fbaecfbcef870b028fd1e53b (sha256)
which is also a checksum that is expected by the current repo's metadata (primary.xml).

Same situation for "bind-libs-lite-9.9.6-6.P1.fc22.x86_64.rpm" - From the log you've attached [1], the expected checksum was:
0ccc510c9213579116be043b59056d218f1652ee42089a9de6008d8eed2ae9c1 (sha256)
while the real checksum is:
45a73569aa9c5a1b76f1d0283d7ff7ae8b03454a4e65966098d05763ba39bd79 (sha256)

I have no idea how primary metadata could contain correct filenames (which are composed from name-version-release) and had bad checksums in the same time.

Next time you see the error, could you please also grab a local cached copy of the metadata that was used by DNF and send it to me?

For rawhide the path is:
ls /var/cache/dnf/<ARCH>/<FEDORA_VERSION>/rawhide/repodata/*-primary.xml.gz
E.g.:
ls /var/cache/dnf/x86_64/21/rawhide/repodata/5d54d6c88e1d3de80daab17135e2273fdc6c3827efcf44e3156e0b0dbf6d9edd-primary.xml.gz

Note: This file could be a quite big (e.g. 11Mb) so you probably won't be able to attach it to the bugzila, but it would be nice if you could share it with me by any other way, choice is up to you.

Regards
Tomas

Comment 26 Tomas Mlcoch 2014-12-18 13:00:35 UTC
A side note: As could be seen in the log, the downloads of some file were restored (the exactly same filenames already existed in dnf cache and librepo just try to continue with these unfinished downloads. I.e. download only the missing pieces instead of downloading whole files again):

select_next_target: Selecting mirror for: Packages/g/gcc-4.9.2-2.fc22.x86_64.rpm
prepare_next_transfer: URL: http://download.fedoraproject.org/pub/fedora/linux/development/rawhide/x86_64/os/Packages/g/gcc-4.9.2-2.fc22.x86_64.rpm
prepare_next_transfer: Used offset for download resume: 18544320
lr_download: Downloading started

In that case (in case of resumed downloads), I could imagine that the files could get corrupted (somehow), but it doesn't explain why were expected different checksums - which is the problem here.

-- Brain dump --

It's really rare and unusual that two packages with the same filenames have different checksums.

Koji (Fedora's build system) doesn't let anyone to build a package with NVR (name-version-release) that already exists. Thus every package filename which is produced by Koji is unique.
Of course, with exception for scratch builds - for scratch builds the uniqueness constrains don't apply, but scratch build are only for testing by developers and never goes to repositories.

Another case when two packages with the exactly same filenames could have different checksums is in a case when they are signed with different keys (or one is signed and the second one is not).
But AFAIK, unsigned packages should never get into any official fedora repo.

Comment 31 Tomas Mlcoch 2014-12-22 12:48:47 UTC
Thanks! From what I see, the expected checksums are correct. The issue must be elsewhere.

I see that a lot of downloads were resumed - i.e. there already existed a files with the same filenames but with smaller size that the expected ones.

The main question is where did all this partially downloaded files come from?

This could be a sign of some kind of race condition. Something like two or more processes downloading a same file into the shared dnf cache and thus writing simultaneously to a same file which would led to such errors.

Could you please next time also append one of the partially downloaded files that were reported in a log as the one with non-matching checksum (the smallest one to save your bandwidth would be sufficient).
The files should be stored in:
/var/cache/dnf/<architecture>/<fedora_version>/fedora/packages/
E.g. /var/cache/dnf/x86_64/21/fedora/packages/

What is interesting, in my case when I manually break a dnf download then no files are kept in the cache, thus I wonder where all your partially downloaded files goes from.

Comment 34 lejeczek 2014-12-23 10:51:34 UTC
also, yum update worked for packages dnf failed, not for all, I had to skip broken.
Also dnf seems to miss some updates, yum update:
yum update freerdp-libs
fails for other dep problems, but dnf update freerdp-libs has/finds no updates
even though:

I tried to manually delete the content of /var/cache/dnf/x86_64/ but interestingly enough, it still downloaded the DRPMs. Hence I added "deltarpm=false" to be able to update my system. This is just workaround though.

Comment 38 Berend De Schouwer 2014-12-31 07:45:34 UTC
when I get this, I can fix it by manually removing the affected .rpm and .drpms in /var/cache/dnf/

It looks like if I've got a partial file dnf continues from the previous last download point.  If, however, the partial file is corrupt, it always continues to append to a corrupt file, and thus is stuck in an infinite loop with bad checksums.

I'll try and manually corrupt a large partial download.

Comment 39 lejeczek 2015-01-05 09:22:14 UTC
above (38) does not do anything for me, besides - dnf clean - does this and should be no need for any manual intervention.
I my case it's not a problem with partially downloaded / corrupted packages, nothing in local disk cache and still checksum doesn't match.

Comment 40 Honza Silhan 2015-01-05 17:50:52 UTC
Thanks for collaboration to all. Issue with partially downloaded files from comment 38 (and maybe the others too) could be fixed when PR [1] solving bug 1157233 is merged. This change will be in dnf-0.6.4.

Comment 41 lejeczek 2015-01-07 12:32:28 UTC
there is definitely something wrong with dnf on my system. Today again (it happend before) my gnome notification told me there are some updates, asked to install them, "Restar & Install" and everything dnf a minute ago was failing about (checksums) went in perfectly fine.

Comment 42 Vít Ondruch 2015-01-07 12:47:39 UTC
(In reply to lejeczek from comment #41)
Are you speaking about gnome-software updates? They use packagekit in background and not dnf.

Comment 43 lejeczek 2015-01-07 13:05:10 UTC
exactly what I was saying - something wrong with dnf and it ain't partial/broken/incomplete package downloads.

Comment 44 Berend De Schouwer 2015-01-08 04:15:28 UTC
This may be relevant:  I don't use gnome-software updates because it downloads on expensive networks, and I've switched dnf metadata to very long for the same reason.  I initiate manual downloads on cheap networks, dnf only.

Therefore my pre-conditions are different to lejeczek's.

Comment 45 lejeczek 2015-01-09 15:33:19 UTC
I've fiddled a bit with dnf.conf, added:

keepcache=0
deltarpm=0
metadata_expire=3m

this seems to solve my checksum mismatches. (for now at least, will do more fiddling)

Comment 49 Tomas Mlcoch 2015-01-16 15:22:18 UTC
Hi all,

I've made several changes to Librepo that should fix this issue.
These changes are now available in the librepo git and also new build for rawhide is ready and should be available in rawhide repository soon.

The build: http://koji.fedoraproject.org/koji/taskinfo?taskID=8639651

In this version, librepo tries to resume any download only once.
If this one attempt fails in next try the whole file is downloaded from scratch.
Also, the librepo tries to resume only files that were originally being downloaded by librepo.
This behavior is achieved by xattr flag, that is set for each downloaded file during downloading and is removed when the file is successfully downloaded.
If a librepo process is interrupted during a download process, the partially downloaded files still have the flag and could be resumed.
Other files are not considered trustworthy and such files will be downloaded from scratch.

Comment 55 Andrea 2015-01-29 10:43:52 UTC
I've just tried the new librepo 1.7.13 and I did not see any improvement.
I am on Fedora 21 x64 in a corporate environment behind a proxy.
Fedora 21 is fully updated as of this morning 29/1/15

after "yum clean all", yum needs 5 minutes to download the metadata, trying various mirrors and doing partial downloads. The log is at the bottom of this comment.

did the same with dnf and it tries forever to download a file.


Fedora 21 - x86_64    37% [=======-            ]  26 kB/s |  15 MB     16:08 ETA


it goes almost at 100%, then starts again, then stops halfway, starts again.... After more that 1 hour nothing else happened.
Other times, the target size is 39 MB, it varies.

The proxy I need to use does some file inspection and sometimes blocks the download almost at the end while it checks the file and then continues.

yum never had an issue with this, and after a few try / partial downloads, in 5 minutes finishes the job.

here is the output of yum. I was not able to find a similar verbose output for dnf.

Comment 56 Suhan Andrei 2016-01-04 05:06:09 UTC
Hi , 

I am seeing this in fc23 . once fastest mirror gets broken , updating/installing new packages becomes crawls to halt . there shall be some logic in dnf or librepo to downgrade a once broken mirror - speeds are not constant over time -  ( timeout setting in dnf does not help too much ) as after a timeout the mirror is not downgraded as being slow .

How to test : note fastest mirror and block it in firewall or change in /etc/hosts its hostname to point to an non existing ip , or to a system which has no repo . The actual result is that dnf stil tries to download from broken mirror instead of expected result of trying others .
