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:
pyhoca-cli[12140] NOTICE: preparing requested X2Go session

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
-P 20170316113957420 -L"):
pyhoca-cli -P 20170316113957420 -R appheads-50-1489690847_stDXFCE_dp24
then sometimes I get the same error as above.
