Milestone: 2.3
Resolution: invalid
Status: newclosed

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.
