Description Russell Odom 2015-11-23 13:47:09 UTC
Description of problem:
On attempt to upgrade from Fedora 21 to 23, "dnf system-upgrade download --releasever=23" reports "cannot install both mozjs17-17.0.0-12.fc23.x86_64 and mozjs17-17.0.0-12.fc21.x86_64"

Version-Release number of selected component (if applicable):

How reproducible:
Every time

Steps to Reproduce:
1. Have a Fedora 21 system with mozjs17-17.0.0-12.fc21.x86_64 AND mozjs17-17.0.0-12.fc21.i686 installed
2. dnf system-upgrade download --releasever=23

Actual results:
[root@gigalith ~]# dnf system-upgrade download --releasever=23
cannot install both mozjs17-17.0.0-12.fc23.x86_64 and mozjs17-17.0.0-12.fc21.x86_64

Expected results:
Download proceeds as expected

Additional info:
Not sure if this is a dnf bug or a mozjs bug, or something else.

[root@gigalith ~]# rpm -q mozjs17
[root@gigalith ~]# rpm -qa | grep dnf

Removing the i686 package makes the problem go away (don't know why I have it, it's not required by any other package I have installed, but this is an ancient system that's been incrementally upgraded since F13).

Sorry, not much we can do here. Does it work if you specify add --best --allowerasing?

Comment 2 Russell Odom 2015-11-30 22:14:18 UTC
I'm afraid I can't test it now - I removed mozjs17-17.0.0-12.fc21.i686 manually and the upgrade to F23 then completed OK.

Comment 3 Luc de Louw 2015-12-05 11:07:05 UTC
--best --allowerasing does not work. I also had to remove mozjs17-17.0.0-12.fc21.i686 plus additionally kdeplasma-addons

Comment 4 Fedora End Of Life 2016-11-24 13:39:40 UTC
This message is a reminder that Fedora 23 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 23. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '23'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 23 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Comment 5 Fedora End Of Life 2016-12-20 16:11:51 UTC
Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 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

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