The user says that not the individual accounts' shell was set to
/bin/dash, but the system-wide default shell.
And changing it to /bin/bash fixed the issue for them.
Grepping through the X2Go code, I found several instances where /bin/sh
is used (/usr/sbin/x2golistsessions_root, /usr/sbin/x2gocleansessions,
/usr/bin/x2gopath, /usr/bin/x2gobasepath, /etc/init.d/x2goserver,
/usr/bin/x2goprint).  There is also a match in the /usr/bin/x2goagent
binary.

Could it be that x2gostartagent itself is being called in a way that
skips the shebang line? (e.g. "/bin/sh -c /usr/bin/x2gostartagent")


Kind Regards,
Stefan Baur
