Here's the traceback, from the log:

  Jan 16 21:52:18 ERROR Failed loading plugin: system_upgrade

  Traceback (most recent call last):

    File "/usr/lib64/python2.7/importlib/__init__.py", line 37, in import_module
      __import__(name)

      t = dnf.pycomp.gettext.translation(name, fallback=True)
  AttributeError: 'module' object has no attribute 'gettext'

That last line of code does not exist in dnf-plugin-system-upgrade-0.5.0.

Did you maybe try to install dnf-plugin-system-upgrade from source, or install a package from F22+?

I recommend you check the versions for the plugin subpackages:

  rpm -qa "python*-dnf-plugin-system-upgrade"

and reinstall those packages to get the correct code.

(In reply to Will Woods from comment #1)

Hi Will,
  Thank you for the fast reply.
  I did a dnf upgade and then when it failed I did it from source.
  This was the output from rpm -qa "python*-dnf-plugin-system-upgrade"
    python2-dnf-plugin-system-upgrade-0.5.0-1.fc21.noarch
  When I tried to remove it said no such file or dir
  A dnf list showed python3-dnf-plugin-system-upgrade.noarch-0.5.0-1.fc21
  I removed that and dnf-plugin-system-upgrade-0.5.0-1.fc21.noarch
  I then did a dnf system upgrade and the plugin seemed to work
    ( the upgrade failed due to VirtualBox, I'm working on that)

  Thank you for your help, it was not a bug, just a dodgy system,
    although the RPM output is interesting.
  I don't know how to close the bug, can I leave that to you?

  Thank you again
  Paul
