Just updated our productive wiki from v1.28.2 to v1.29.0.

Run same procedure as always and for sure ran "maintenance/update.php".

I can view our wiki but cannot login.

Whenever I try to log in I get an "Fataler Ausnahmefehler des Typs „Wikimedia\Rdbms\DBQueryError“!" which means fatal error.

Debug output :
Error: 1054 "Unknown column 'ug_expiry' in 'field list'".

Solution:
I had to add column 'ug_expiry' manually to DB.

Related reports (found by searching for debug output):

• T162495: Patch for expiring user-groups did not apply correctly
• T160686: ug_expiry column of the user_groups table is not present on Labs

Basic problem:
Update script is not adding missing column
