Description Kamil Páral 2021-02-12 15:05:24 UTC
Description of problem:
In bug 1882358 we resolved a problem where certain "addon" package groups weren't marked for installation by default, when KDE was selected to be installed in netinst. In particular, we changed this in comps:

    <name>KDE Plasma Workspaces</name>

to this:

    <name>KDE Plasma Workspaces</name>
      <groupid default="true">firefox</groupid>
      <groupid default="true">kde-apps</groupid>
      <groupid default="true">kde-media</groupid>
      <groupid default="true">kde-office</groupid>

So 4 addons should be now selected by default. That really happens when I boot a F34 netinst. However, it doesn't happen when I boot F33 netinst. In F33 netinst, all addons are still unchecked by default.

I looked at /tmp/dnf.cache/ and I confirmed that both 'fedora' and 'updates' repos were downloaded, and that the 'updates' repo file contains <hash>-comps-Everything.x86_64.xml.gz which does include the correct changes as shown above.

I have a suspicion that even though both 'fedora' and 'updates' repos are downloaded, anaconda uses only the comps from the 'fedora' repo (or e.g. the first repo defined, or perhaps a random repo).

Below, I attach logs from my F33 netinst.

Version-Release number of selected component (if applicable):
anaconda 33.25.4-1.fc33

How reproducible:
always, it seems

Steps to Reproduce:
1. boot F33 netinst
2. select KDE in Software Selection, see that no addons are checked by default
3. compare this to F34 netinst
4. confirm that the downloaded 'updates' repodata contain correct comps with default="true" next to certain KDE addons

Additional information:
If this is truly a bug, I understand this will no longer be fixed for F33. But I'd like to avoid the same situation in the future.

Comment 7 Vendula Poncova 2021-02-16 11:03:58 UTC
I had some theories, but none of them seems to be related to this issue. I would guess that it depends on the priority of the repositories. Reassigning to DNF for further investigation.

Comment 8 Daniel Mach 2021-02-17 07:55:59 UTC
Comps merging depends on load order of the repositories.
It is the only option because the repo configuration has no other way to say what should come first.
There's the 'priority' option, but it is meant for packages and using it for comps would cause a lot of damage.

From the packaging log:
> 14:24:47,091 DBG packaging: repo updates: fall back enabled from default repos
> 14:24:47,091 DBG packaging: repo fedora: fall back enabled from default repos
That means load comps from 'updates' and override it with comps from 'fedora'.

Is Anaconda sorting or preserving order of the repos?
Does it load them in them in the order they were specified by the user?

Comment 9 Vendula Poncova 2021-02-17 10:21:19 UTC
These repositories are loaded from the configured directories with the DNF's read_all_repos method. I don't think that Anaconda changes their order after that. We only disable or enable them. Based on the implementation of the read_all_repos method, the .repo files are sorted by their path, so they are processed in the following order:

> find / -name *.repo | sort

Comment 10 Daniel Mach 2021-02-23 12:25:55 UTC
Could you try the following dnf change?

Comment 11 Kamil Páral 2021-02-24 11:25:53 UTC
Vendula, if you can build an updates.img containing the change, I'll be happy to test it 🍰

The fix seems to work fine. Here is the updates image:
