Xpra: Ticket #1759: Using xpra v2.2.2 I get tracebacks trying to start an application

$ xpra --version
xpra v2.2.2-r18021

Both servers are running Ubuntu 18.04 (I am testing it)

I installed xpra using the Binary's for Ubuntu 17.10 from https://xpra.org/dists/artful/main/binary-amd64/

The same XPRA version is on both the client & server.

When I try to start an application from the client to the server I get these errors...

$ xpra start ssh/bmullan@ --start-child=xterm

Thu, 01 Feb 2018 15:35:14 GMT - Antoine Martin: status, component, description changed; resolution, milestone set

undefined symbol: PyFPE_jbuf: errors like these happen when packages are installed on a different distro than the one they are intended for, or when the distro is still seeing large ABI break as part of its development process. The final packages should be fine.

I've just pushed some new beta packages: http://xpra.org/beta/bionic, those should work better if the rest of your system is also up to date.
