The issue you are facing:
I upgrade to 15.0.0. The web based upgrade went well until occ upgrade that returns an error:
# occ upgrade
Nextcloud or one of the apps require upgrade - only a limited number of commands are available
You may use your browser or the occ upgrade command to do the upgrade

I downloaded the full Nextcloud 5 package manually and replaced apps/user_external with the one from the zip, same error.
I tried removing apps/user_external, same error.
