Can you elaborate more about removing lockfile_pid, please? Have you touched DNF internal locks `/var/cache/dnf/*_lock.pid`?

Comment 2 George R. Goffe 2016-01-11 21:51:54 UTC

Jan,

All I did was look at the lockfile_pid at the location complained about by "dnf". I did not touch anything else, either to remove or otherwise.

George...

Comment 3 Honza Silhan 2016-01-19 14:00:54 UTC

we'll take a look.

Comment 4 Jan Kurik 2016-02-24 15:29:44 UTC

This bug appears to have been reported against 'rawhide' during the Fedora 24 development cycle.
Changing version to '24'.

More information and reason for this action is here:
https://fedoraproject.org/wiki/Fedora_Program_Management/HouseKeeping/Fedora24#Rawhide_Rebase

Comment 5 Fedora Admin XMLRPC Client 2016-07-08 09:31:57 UTC

This package has changed ownership in the Fedora Package Database.  Reassigning to the new owner of this component.

Comment 6 George R. Goffe 2016-07-22 16:31:12 UTC

Igor,

I have not seen this bug since I reported it so I suspect that it would be ok to close it. If I encounter it again, I'll make a new bug or re-open this one.

Thanks to everyone who helped with this,

George...
