Current Behavior

Receive error while upgrading from v0.8.0 via databricks labs command.

Attempted method to upgrade:
databricks labs upgrade ucx --debug

Error received:

Also a bit weird that when I run:
databricks labs installed --debug, I see:

Name Description Version
ucx Unity Catalog Migration Toolkit (UCX) *

(i.e. no version displayed).

Is 0.8.0 "too old" a version to run upgrade? Is my only option to manually delete and re-install?

Expected Behavior

Running upgrade command should enable me to upgrade to 0.21.0, or most recent ucx version.
