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--- root@control01:~# openstack network agent list Traceback (most recent call last): File "/usr/bin/openstack", line 6, in <module> from openstackclient.shell import main File "/usr/lib/python3/dist-packages/openstackclient/shell.py", line 23, in <module> from osc_lib import shell File "/usr/lib/python3/dist-packages/osc_lib/shell.py", line 24, in <module> from cliff import app File "/usr/lib/python3/dist-packages/cliff/app.py", line 22, in <module> import cmd2 File "/usr/lib/python3/dist-packages/cmd2.py", line 585, in <module> _ = pyperclip.paste() File "/usr/lib/python3/dist-packages/pyperclip/__init__.py", line 667, in lazy_load_stub_paste copy, paste = determine_clipboard() File "/usr/lib/python3/dist-packages/pyperclip/__init__.py", line 558, in determine_clipboard return init_gi_clipboard() File "/usr/lib/python3/dist-packages/pyperclip/__init__.py", line 167, in init_gi_clipboard gi.require_version('Gtk', '3.0') File "/usr/lib/python3/dist-packages/gi/__init__.py", line 129, in require_version raise ValueError('Namespace %s not available' % namespace) ValueError: Namespace Gtk not available ---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.
