Took another swing at upgrading from #debian #bookworm to #trixie.
apt-upgrade --without-new-pkgs done first, then normal apt upgrade, then apt dist-upgrade.
Checked #udd for bugs etc, plus a quick re-read of the release notes.
This time things worked better, because I fixed some sources before the upgrade and removed a couple of things I'd gotten from deb-multimedia which had compromised certain aspects of the upgrade last time I tried.
Mostly painless, and all working. I've stuck with #xfce for the desktop, at least for now whilst testing #kde in a VM.
I had to do a 'pipx reinstall-all' to fix the underlying #python in those virtual environments.
And had to do #python virtual environment upgrades in my normal venv folders for the handful of things I run that don't seem to like #pipx
All done and will now monitor and record any issues, and raise bugs if I get anything serious. But I doubt anything will be a problem given the imminent release of #trixie in the next 6 to 8 weeks.
