Problem upgrading / reinstalling xfce power manager

[ian-weisser]

The following packages have unmet dependencies.
 xfce4-power-manager : Depends: upower (>= 0.99) but 0.9.23-2ubuntu1 is to be installed
                       Recommends: xfce4-power-manager-plugins but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Take a look at upower in the various releases of Ubuntu:

$ rmadison -u ubuntu upower
 upower | 0.9.23-2ubuntu1       | trusty           | source, amd64, arm64, armhf, i386, powerpc, ppc64el
 upower | 0.9.23-2ubuntu2       | utopic           | source, amd64, arm64, armhf, i386, powerpc, ppc64el
 upower | 0.99.2-1              | vivid            | source, amd64, arm64, armhf, i386, powerpc, ppc64el

So you are running Trusty (14.04), but xfce4-power-manager wants a newer version (15.04).
That usually indicates that you have added an inappropriate repository to your Software Sources and created a version conflict.

Generally, it's easy to fix, once we discover the inappropriate source.
Please run the following two commands, and post the entire output here.

apt-cache policy xfce4-power-manager
apt-cache policy upower

you've tried removing xfce power manager , did you remove all the dependencys with it?

in this order:
sudo apt-get purge xfce4-power-manager && sudo apt-get autoremove && sudo apt-get autoclean

that should remove everything, that has to do with xfce4-power-manager.
then can try installing it fresh:
sudo apt-get install xfce4-power-manager

Thank you but this produced the same error as before.

That's likely the issue. You have the xubuntu-staging PPA enabled, which is trying to install xfce4-power-manager 1.4.2 while ubuntu 14.04 provides 1.2.0. I would remove the PPA:

sudo apt-get install ppa-purge
sudo ppa-purge ppa:xubuntu-dev/xubuntu-staging

If you know for certain you have not installed any other packages from xubuntu-staging (you can check this using synaptic) you can just remove it from your software sources without using ppa-purge.
