Hi there,
I can log onto PUMA, and then Met Office Science Repository Service (with password). However, on puma I could not open umui to submit job to ARCHER. umui normally worked well before, but I did not use PUMA for about 4 months. Can you help?

you need to enable X11 forwarding. When you ssh, use the command ssh -Y [your name] and this should work.
