Summary of the issue you are facing:
I updated my self-hosted installation of Nextcloud from 32.0.3 to 32.0.4 using updater.phar. The update proceeded normally, until it came to running “occ upgrade”.
When running it, I see the following log output:
Should the "occ upgrade" command be executed? [Y/n]
Setting log level to debug
Repair step: Repair MySQL collation
Repair info: All tables already have the correct collation -> nothing to do
Repair step: Copy data from accounts table when migrating from ownCloud
Repair step: Drop account terms table when migrating from ownCloud
Updating database schema
Exception: Database error when running migration 33000Date20251209123503 for app core
Index "mounts_user_root_path_index" does not exist on table "oc_mounts".
Update failed
Maintenance mode is kept active
Resetting log level
"occ upgrade" failed - return code: 5
This can be reproduced by either rerunning the updater or by running “occ upgrade” manually. While searching for a solution, I found the suggestion to run “occ db:add-missing-indices”. I ran the command, getting the following log output (no mention of the missing index):
Adding additional fs_parent index to the oc_filecache table, this can take some time...
oc_filecache table updated successfully.
Adding additional fs_name_hash index to the oc_filecache table, this can take some time...

Adding additional cards_prop_abid_name_value index to the oc_cards_properties table, this can take some time...
Removing cards_prop_abid index from the oc_cards_properties table
oc_cards_properties table updated successfully.
However, I still could not run the upgrade successfully - same error as before.
How can I get my Nextcloud installation to complete the update?
Steps to replicate it (hint: details matter!):
- Have a running Nextcloud 32.0.3
- Run upgrader.phar
- Observe issue

Tips for increasing the likelihood of a response
- Use the
preformatted textformatting option in the editor for all log entries and configuration output. - If screenshots are useful, feel free to include them.
- If possible, also include key error output in text form so it can be searched for.
- Try to edit log output only minimally (if at all) so that it can be ran through analyzers / formatters by those trying to help you.
