Open Stack

Hi *,

today I upgraded my virtual test environment from V to W when (Ubuntu  
20.04) all of a sudden cli commands didn't work anymore with this  
stack trace:

---snip---

I found this bug [1] describing the same issue but there has been no  
progress. I posted my comments there as well. I found one way to get  
the openstack shell to work by installing libgtk-3-dev (I found a hint  
in a search engine). Apparently, python3-cmd2 requires  
python3-pyperclip which requires python3-gi and so on. Is this really  
the desired way? I didn't notice anything in the release notes (maybe  
I missed it). When comparing to a different environment (Victoria on  
baremetal) I see that libgtk-3 is installed there (not -dev though),  
but even with libgtk-3-0 the error message was still present. So the  
question is, which dependencies are missing where? It's not really  
obvious to me. Could this already be fixed in Xena? If it is fixed  
there I could do the double upgrade, of course, especially since  
Wallaby is already under extended maintenance. Any comments are  
appreciated.

Thanks,
Eugen
