Based on #2549#comment:6 this comment, I would expect that it would work for Ubuntu.

I tried to find xpra/platform/path.py tool to check if there is more information, but there seems to be nothing:

$ locate */path.py | grep xpra
$

My case:

This turned out to be a "typo": r25181. You can apply this by hand, this will be in the next builds.

See also: r25182, r25183, r25184.

-Important*: see notes in #2567#comment:4.
