After installing updates today Ubuntu 17.10 server with x2gonightlybuilds now will not allow me to connect. When I try I get a pop-up that says:
Connection failed. /usr/lib/x2go/x2gogetrandomport: line 106:
get_random_port: command not found Unable to get
(pseudo-) randomized starting port value.
The stable build still works except the xrandr version issue which waswhy I have been using the Nightly Builds on Ubuntu.

Actually I totally purged everything and re-installed, no help.This is what the file looks like:

[x2goagent] # Value can be either "host-based" or "pure-random". # This is currently a workaround for a bug in X2Go Client, that uses a 1:1 # mapping of source to destination ports for SSH tunnels. # This leads to problems if opening two (or more) instances of X2Go Client # and connecting to two machines that use the same tunneling ports. # Such a scenario is easy to trigger: make sure that both machines have run # no active sessions, than spawn one session on each machine. # Connecting to both at the same time will not be possible without a means # of randomization. # The randomization can either be "host-based", in which case the port will # be set to 30000 + (128 * last octet of IPv4 address) and does the job if # the last octet of the machine's IPv4 address is known to be unique, or # "pure-random" which uses the (not so truly random) bash ${RANDOM} # variable to fully randomize the port, i.e., 30000 + random(0..32767). port_randomization="pure-random"
[log] # possible levels are: emerg, alert, crit, err, warning, notice, info, debug loglevel=notice

Thanks for testing this stuff!
As root:
sed -i -e 's/get_random_port/get_pure_random_port/' /usr/lib/x2go/x2gogetrandomport
I've also just pushed a commit fixing this issue, but just running the sed comment should be equivalent for you.

All this code is new, so I'm not surprised. :)

Hmm, that line doesn't match up with the actual sources. I see what's going on. That'll require some more work.
