kubuntu-desktop is already the newest version (1.338).
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 kde-telepathy-minimal : Depends: kde-config-telepathy-accounts (>= 15.04.0) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

So I tried that:

So that doesn't work. I'm not sure how to proceed from there. This seems somewhat non-intuitive.

I thought that maybe aptitude is more clever and tries to help me more. So I tried:

root@gcomputer:~# aptitude remove account-plugin-google

Accept this solution? [Y/n/q/?]   (I typed Y. Not sure but I hope the best.)

So, that seems to have done something. Not sure if it was fine. The final message is a bit confusing. 0 (-1) broken == 0 (+1) fixed?

I wanted to check with apt-get again:

Use 'apt autoremove' to remove them.

I still wonder about these kde-telepathy things. They are optional? I don't have them now? They are broken?
