Nextcloud web not working after last update

Apps

Dear Boris,

Unfortunately, our Nextcloud instance is no longer accessible via the browser following the recent update; however, the synchronization applications on our PCs continue to function correctly. I have forwarded the log file to you and would be most grateful if you could investigate the cause of this issue.

Many thanks,

Rudy

I will try to make this better as this is a known Nextcloud issue, did anything unusual happen before this, like a power outage?

Dear Boris,

We are encountering a persistent issue with the admin account in Nextcloud, which is not being recognised as an administrator. We have reviewed several posts here and implemented the suggested solutions, but to no avail. We remain committed to resolving this matter; however, it appears that a fresh installation of Nextcloud may be the only viable solution. Given that our Nextcloud instance supports our wine bar and serves a large number of users, we have continually postponed this action.

Best regards,
Rudy

Let me check that, I may be able to fix it. I will come back soon

10

Can you actually start a new thread please on that.

11

Update 924 should be available in an hour or so, could you upgrade please and let me know if admin users are admins again In Nextcloud.

Also could you confirm that admin user can login to Users apps and is part of Syncloud admin group?

12

Greetings, Boris. Regrettably, I am unable to initiate the update on any of my three devices, all of which are Raspberry Pis. Furthermore, Nextcloud has become inaccessible without a restart.

13

Sorry are you saying latest Nextcloud update broke it? What error do you see?

14

yes the last version, had no error message; it simply stop update

A brief update: Nextcloud operates on our business device, although no updates can be performed. On my personal device, Nextcloud appears to have disappeared.

This is probably justt attempting to upgrade in the background, do not try to fix it for now, the fix is coming I the few hours.

18

Could you upgrade now please?

19

I have attempted the process, and the outcome is as follows: the download on my device indicates an upgrade, which is aborted after a few minutes. I try again

20

Can you show refresh log or send device logs?
