Steps to reproduce

To be confirmed:

  • Call ./mtui.py -s paris.qam.suse.cz -w 1
  • Wait indefinitely?
  • See the above error

Impact

Just cosmetic

so you get a traceback along with the error when a host is not reachable. What expectations do you have how MTUI should behave?

I expect getting the error in MTUI without any traceback.

  • Target version changed from Ready to future

Adjusted the ticket description according to https://progress.opensuse.org/projects/openqav3/wiki/#Defects . I recommend to create tickets following such template as that can make reproduction and fixing easier for the developers. I also reduced the priority as I understand the impact is only cosmetic. Please correct me if I got that wrong though.

I tried to reproduce the error with

./mtui.py -s paris.qam.suse.cz -w 1

which yields

info: connecting to paris.qam.suse.cz
critical: connecting to paris.qam.suse.cz failed: [Errno 110] Connection timed out
warning: failed to add host paris.qam.suse.cz to target list

So this does not reproduce the error. Can you help me to provide "steps to reproduce"?

I took a look myself and tried to reproduce the problem but could not find any tracebacks. Can you help me to find proper "steps to reproduce"?

we need better "steps to reproduce" before we could fix the issue

Hello.

I am no longer able to reproduce the issue.
I am using he development version of MTUI, so this was probably only temporary hiccup.
Feel free to close the issue. I will reopen if I manage to reproduce again.
