API version 2020-04-01-preview does not have operation group 'role_assignments'

[3vi1]

The following occurs when trying to display the assignment list from the 'az role assignment' on Linux. The same command, runs without error from the same version of az in the cloud shell, with the same core and telemetry versions.

Command Name
az role assignment list

Errors:

Expected Behavior

Environment Summary

Linux-5.8.0-36-generic-x86_64-with-glibc2.32
Python 3.9.1
Installer: PIP

azure-cli 2.17.1

Extensions:
azure-devops 0.19.0

Additional Context

az role

This appears to be similar to #13827. Backleveling to azure-cli 2.16 worked as a workaround. The same command works fine from that version.

This issue is not the same as #13827 because the error Unsupported API version '2020-04-01' for Network Resource in #13827 is returned by the service, while this error ValueError: API version 2020-04-01-preview does not have operation group 'role_assignments' is purely a client-side error.

As you installed Azure CLI via pip, please make sure azure-mgmt-authorization is installed correctly as Azure CLI requires:

azure-cli/src/azure-cli/setup.py

Line 68 in 2d9c7fc

'azure-mgmt-authorization~=0.61.0',

TL; DR: This SDK is not merged to the master branch of https://github.com/Azure/azure-sdk-for-python, so you won't find the source code there: https://github.com/Azure/azure-sdk-for-python/blob/2383277a260ac100593c15a3326c44dd45440824/sdk/authorization/azure-mgmt-authorization/azure/mgmt/authorization

pip is not a recommended way of installing Azure CLI. We recommend installing official Azure CLI packages as documented by https://learn.microsoft.com/en-us/cli/azure/install-azure-cli.
