I'm upgrading 11.4 to 12.1. What's annoying in
zypper dup is that after about a minute it goes background. Output to console is still active, but I lose the ability to do stdin. A message appears saying
+ Stopped zypper dup
or something like that. I can't do anything when zypper prompts me something. I tried doing
fg but I get
zypper dup + Stopped zypper dup + Stopped zypper dup
How can I restore stdin to zypper or at least tell it to go ahead with retry command?
