@claudi Your system has some packages installed (or held) that conflict with the ones about to come from the repository. Attempting to upgrade manually with apt should tell you what exactly is the issue.
@dos Thanks! I'm not sure I understand exactly what you mean by upgrading manually.
My interpretation would be that you meant something along the lines of "upgrade your sources list manually and then run `apt update && apt full-upgrade` on your own". Does that fit what you meant?
@claudi Yup. You can fix whatever shows up there and then go back to the GUI upgrader if you wish.
@dos What's the best channel to address this error message? (Been struggling for a few months until my install finally met all the prerequisites today)
