2 questions: 1.
Recent upgrade of python3.8 and related packages (namely `python3.8` `python3.8-minimal` `libpython3.8` `libpython3.8-stdlib` `libpython3.8-minimal`) from 3.8.3-1 to 3.8.4~rc1-1 breaks xpra, causing it unable to create new X sessions. An example is to run `firejail --x11=xpra xeyes` (omitting other seemingly not related log messages): https://pastebin.com/KSrBbQcj Using vanilla xpra shows similar errors when trying to launch any app with it. Luckily I had cached 3.8.3-1 packages locally, and downgrading to 3.8.3 made xpra happy. I guess some interfaces in python might have changed going from 3.8.3 to 3.8.4, but I don't know how to dig in to figure out more. Who should I reach to have a further look into this? Debian bullseye, amd64 --- 2. Apart from this issue, I just realized that I was unable to downgrade to 3.8.3 if I had not cached the deb files. All mirror sites I could find were all updated to have only 3.8.4~rc1-1. Is there an archive that keeps older versions?
