Hey hey! Looks like @kde Neon has been rebased to 24.04 aka Noble. I started the upgrade right away. The upgrade script crashed halfway because of some problem with apt configuration (probably my fault) but I cleared the error and finished it by hand with "apt dist-upgrade". Reboot, ok.

I only had to purge all that snap+apparmor nonsense that was preventing thunderbird from opening web links and crashing @Vivaldi browser. I really do not understand the point of apparmor outside of server world. How can you be so arrogant to think you'll be able to predict all the possible uses of a consumer software, and decide that it is ok to cause all the other uses to fail with only a cryptic error message buried in the system logs?
