I've (inline-)upgraded my second Ubuntu-MATE PC today, from 23.10 to 24.04.1.
This was the smoothest upgrade during the last 8 years since I use Ubuntu-MATE! (after having an extremely bad experience upgrading my daily driver Ubuntu-MATE PC late April.2024 - see my comment here at that time)
I had to re-install
- WineHQ - the "devel" version (required for Notepad++ and HeidiSQL) - the "stable" version did not install!
Other observations
- had to restart three times until everything worked as expected (no other additional actions performed!) - but this was NO PROBLEM for me
- the "Clock Preferences / Weather" works for me, again (used "Meteo" while this simple / convenience tool did not work - and will continue to use "Meteo" - see my comment here)
