Upgrade 32 bit to 64 bit

I’ve followed this (only added some users in the users app) and I’ve got quite a long way (I’ve got my contacts and calendars back), but I’ve now run into a problem similar to one I had a couple of years ago, I think when the users app was changed.
Another LDAP problem, I suspect - Syncloud
From what I remember, that time reinstalling Nextcloud fixed it.

This time I added some of the users that are local nextcloud users into the users app. It seems to have created a shadow set of users in nextcloud, rather than linking up to the ones that are there. In the nextcloud users list I see only the (local) members of the abtuse group, and that is the only group listed. I should be a member of that group, but I’m not listed at all, and I’m not recognised as an admin user. The ldap users don’t seem to be listed in nextcloud, and anyone not in a group (eg danny and sarah) isn’t listed.

It looks like something keeps removing and adding me to these groups, but nothing changes. I wasn’t even online 10 and 30 minutes ago.

I’ve tried going through the suggestions in Nextcloud · syncloud/platform Wiki (github.com)

snap run nextcloud.psql -c "select * from oc_ldap_group_mapping"
 owncloud_name |                 ldap_dn                  |            directory_uuid            |                           ldap_dn_hash

When I added some users to the users app it created a group for each of them. I also tried creating abtuse and admin groups in there and then deleted them.

I don’t know if this is out of date, or is showing a serious problem

snap run nextcloud.psql -c “select * from oc_ldap_group_members”
ERROR: relation “oc_ldap_group_members” does not exist
LINE 1: select * from oc_ldap_group_members

I haven’t tried make all admins.

According to this I am in the admin group:

snap run nextcloud.occ group:list
  - abtuse:
    - alex
    - andrei
    - brian
    - bruce
    - cameron
    - graham

The users with numbers are the ones added by the users app.
