- * There is a bug in cmd2 v0.8.5 where an exception is thrown when GTK3

[ Original bug description ]
Openstack release: Wallaby
OS: Ubuntu 20.04 server edition
After installation of python3-openstackclient from apt, while setting up
user, roles and project, I executed following command:
openstack domain create --description "An Example Domain" example
Error:

Had to install GTK3 to make openstack commands work but it is taking
huge time to get a response to the commands. The wait time after firing
any openstack cli command is around 30 seconds.
Anybody faced the issue? What is the fix for it if it exists?
