Red Hat Enterprise Linux 8 systems are not officially supported yet. You can follow the workaround for now:

$ sudo yum install python2
$ sudo yum install yum-utils
$ sudo yumdownloader azure-cli
$ sudo rpm -ivh --nodeps azure-cli-2.0.74-1.el7.x86_64.rpm

Then edit the second line of /usr/bin/az (result of which az) to specify using python2:
PYTHONPATH=/usr/lib64/az/lib/python2.7/site-packages python2 -sm azure.cli "$@"

The exact same problem has appeared on SLES12. It used to work. I can not install this package on new systems, and I cannot update the package on servers where it is already installed.

Expanding the ticket subject to include the specific dependency python-virtualenv may allow this ticket to own this specific dependency problem across all affected platforms.

Was this issue resolved?

Yong Zhang (@yonzhan) There's no proposed solution, no code change/PR and there's me confirming that this really is an issue. This issue is not resolved at all - it's a blocking problem. I can no longer use azure cli for backups because I cannot install it/update it anymore. It's been in use for a couple of years. It's a critical issue for us. I can find ways around it, but I hope we can find a solution - SLES is still indicated as supported in the docs :)

I too got somewhat same error, and python 2.x should not be solution for it since it is going out of service in few weeks.

Having same problem. Installing python2 is not solution for us.

[fengzhou-msft]

It's time to build an el8 package with Python 3.

Also just ran into the same issue. We're already testing with rhel 8 and are transitioning to python3 across the board. Sticking with python 2 isn't going to be an option for us in the future.
