Unfortunately, I know too little about what version of gevent and so=20=20
on=20is in ArchLinux. Sorry for not having responded to this any earlier.

On recent Debian I haven't noticed such an issue, but I know from the=20=20
past=20that we had such an issue.

I will close this issue now in the process of migrating of X2Go BTS to=20=

X2Go=20GitLab's isssue tracker.

Package: pyhoca-cli

Version: 0.5.0.2


I'm using Archlinux and installed pyhoca-cli package from AUR.

Previously I used x2goclient and created several profiles there. Also I 
tried to use pyhoca-gui but it has the same error (bug #1158).

I start x2go desktop session with:


pyhoca-cli -P 20170316113957420 -d


It starts successfully with log:

Then I press Ctrl+C and get an error:

if then I'll try to resume the session (I get it name from "pyhoca-cli

pyhoca-cli -P 20170316113957420 -R appheads-50-1489690847_stDXFCE_dp24


then sometimes I get the same error as above.
