Well, some more details are desired ;-)
Which installation was done: LPAR, z/VM or KVM.
In case of KVM how was it started (cmd-line?)
What was entered during the installation - especially for the archive server?
Is the system able to reach the outside world/internet - and with that the
Ubuntu archives - at all?
(You may start a 2nd ssh d-i instance, and select "Start shell" to test the
connectivity.)
and finally logs are needed, like /var/log/syslog.
Ideally again open a ssh d-i session, select "Start installer (expert mode)"
and further go with "Save debug logs". Select "web" and grab the logs from your
local system via network (probably the easiest way):
local_user@local_workstation:~$ ssh installer@10.245.245.245
