I have an Ubuntu 16.04 desktop installation with Unity and wanted to try KDE, so I ran sudo apt-get install kubuntu-desktop. apt failed with the following message:
trying to overwrite '/usr/share/accounts/services/google-im.service', which is also in package account-plugin-google [...]
The original issue at Ask Ubuntu has several suggestions but none of them worked – any apt commands returned the same requirement to run apt-get -f install, which in turn gave the original “trying to overwrite” error message. synaptic also wasn’t installed so I couldn’t use it (or install it, as all other apt installation commands failed.)
I was able to get the dpkg database out of its bad state and continue to install kubuntu-desktop by running the following:
dpkg -P account-plugin-google unity-scope-gdrive apt-get -f install
