Comment 4 Honza Silhan 2014-10-20 15:31:42 UTC

Hi, thanks for the report.

Did you run multiple instances of DNF or do you know what did you do unusually?

Comment 5 Mikhail 2014-10-20 15:34:25 UTC

Occurs unexpected power failure during the upgrade. Now dnf does not work.

Comment 6 Honza Silhan 2014-10-31 10:11:45 UTC

Then there should be some systemd command that would reset dnf lock after reboot.

Comment 7 Mikhail 2014-12-03 09:41:44 UTC

Problem is still there

Comment 8 Paolo Antinori 2014-12-04 09:32:57 UTC

Comment 9 Paolo Antinori 2014-12-11 13:30:01 UTC

I have been able to FIX my problem  manually removing this .pid file:

/var/lib/dnf/rpmdb_lock.pid

it was empty, probably a result of some error  or crash and it was never removed by dnf, failing as per stack trace above:


  File "/usr/lib/python2.7/site-packages/dnf/lock.py", line 64, in _read_lock
    return int(f.readline())
ValueError: invalid literal for int() with base 10: ''

Comment 10 Honza Silhan 2015-01-09 16:22:09 UTC

Assigning to our expert on locks. Michael, please take a look. You can either use systemd and implement `dnf.lock.release_all()` method or refactor _try_read_lock or any other solution.

Comment 11 Christian Stadelmann 2015-01-17 14:00:17 UTC

Same problem (backtrace) here, probably happened after an unexpected reboot.

In my case the file /var/lib/dnf/rpmdb_lock.pid does not exist. Instead I found /var/cache/dnf/x86_64/21/metadata_lock.pid. After deleting this file (and running `# dnf clean expire-cache`, did that just to be sure metadata was not corrupted) dnf worked fine again.
