Client-initiated shadow fails with ModuleNotFoundError: No module named 'xpra.gtk'

[stdedos]

Describe the bug

It comes in a _usr_bin_xpra.1000.crash format - but I guess there is really nothing interesting there 😕

Also, it might've been a one-off, but I was really tired and just went to sleep instead of re-trying 😓

$ xpra version
xpra initialization error:
 cannot find any live servers to connect to
$ xpra -v
xpra initialization error:
 no such option: -v
$ xpra --version
xpra v5.0.6-r27

$ xpra --version
xpra v5.0.6-r27

This bug does not occur with the current release (5.0.7 at time of writing) and the shadow server does start OK.
Though you do get a similar bug when trying to bring up the about dialog, this is fixed in the commit above.

Idk; AFAIS there is no "current release" ... released (pun intended):

Was it not triggered to build & deploy, perhaps? 😕

Was it not triggered to build & deploy, perhaps?

The focal builds had failed, I kicked them again by hand and:

E: Could not get lock /var/cache/apt/archives/lock. It is held by process 0
E: Unable to lock directory /var/cache/apt/archives/

Don't you love the smell of random buildbot bugs in the morning?
Wiped the shared lock directory, ran again. Good to go now.

Not-a-bonus: you get a newer dummy driver, which would be nice if Debian had not butchered the Xorg builds to make it unusable... so Xvfb it is on Debian / Ubuntu.

BTW, focal?! 24.04 is out soon...

BTW, focal?! 24.04 is out soon...

Yeeeah... I hate OS changes 😅
Especially when they mess up with things deep into the "package state"

I guess I'll go "straight" to 24.04.1 or .2.
