Hello Debian Sid has updated python2.7 and broken a lot of python packages including xpra. Downgrading to 2.7.13-2 works to fix it, but latest sid is 2.7.14 and is verifiably broken.
Lots of bugs, including a couple mentioning xpra.
I believe you need to rebuild with the newer python somehow? I didn't see an issue here for this problem so figured you might appreciate the heads up.

There are no sid packages supported here, this is a Debian downstream bug.
Fair enough. I suspect it'll still be a problem when this migrates to buster, judging by the responses in the bug report (they're just marking the new version of python as breaking the "broken" packages).
