I have upgraded two systems to #Ubuntu 24.04 now and also tried #Thunderbird as snap (which is the default for Ubuntu 24.04) on another machine.
The system upgrades were incredibly smooth. Thunderbird in general also works fine, but it doesn't support #GPG with private keys on a #YubiKey yet (which is my usecase). (Yes,there is a workaround, although clunky.)
So it looks like I'll stay on 23.10 a bit longer on my main machine.
