@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)
@claudi Yup. You can fix whatever shows up there and then go back to the GUI upgrader if you wish.
@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?
