Description Dusty Mabe 2015-07-02 12:24:16 EDT
Description of problem:

When running dnf update in a docker container I noticed that if the DRPM rebuild fails then (because some files get stripped from the docker image) then we can get a *negative* percentage for the amount of reduced size due to delta rpms. This would lead me to believe the calculation is wrong. 

Here is some snipped output from a dnf update -y:

/usr/share/man/man8/udevadm.8.gz: No such file or directory

Comment 5 Fedora End Of Life 2016-07-19 16:48:32 EDT
Fedora 22 changed to end-of-life (EOL) status on 2016-07-19. Fedora 22 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
