Re: Upgrading python3.8 from 3.8.3-1 to 3.8.4~rc1-1 breaks xpra

Thanks Jörg

snapshot.debian.org was a great help! Though I had trouble with apt to deal 
with the downgrade with depedencies, aptitude's interactive UI helped a lot.

As for the xpra issue, it seemed to be something about xpra itself. I just 
found xpra was somehow not in the repo anymore. 
https://tracker.debian.org/pkg/xpra confirmed the removal of xpra, and tracking 
that showed that there seemed to be some issue with moving xpra from sid to 
testing.

Yes, there is: http://snapshot.debian.org/

Upgrading python3.8 from 3.8.3-1 to 3.8.4~rc1-1 breaks xpra

[S. Dash]

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):

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

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?
