This is provided from your hoster?

And it fails from the start, or does it work first and creates this error later, when you 
 (install a certain app, share a file, 
)?

In case it is “dead on arrival”, I’d directly contact your provider, perhaps you forgot to enable something or their installation process has a problem.

Hi, thanks for your answer.

Yes, this is Nexcloud Hub, provided from my hoster. It is a “one click install”, with automated updates and backups.

It was working fine from 2022, when I installed it. I don’t use the web gui on a daily basis, but I use the sync app on several desktops. The other day I noticed the web gui was not working anymore, and I assume it was working until the 30.0.2 update in november. The sync app is still working fine though. I did not make any changes or installed any apps since a very long time, so it must be something else.

Today I tried to backup my installation and data, and then copied the last version files (from the archive provided by Nextcloud) over it. I still get the same error, and the same “Class "OCA\Files\Controller\AjaxController" does not exist” errors in Nextcloud logs.

Then I created a ticket to my hoster, I’m currently waiting for an answer from them.

Interested by the answer you will get. I just upgraded from 28.0.12 to 29.0.10 on Infomaniak, and have the same kind of error, and no access to the app.

5

Interesting. So it’s perhaps an issue in Infomaniak backend ? To be honnest I’ve started suspecting that.
On a side note, I also have an old 17.0.3 Nextcloud (not Hub), also on Infomaniak, which is working fine. It’s still on php 7.3.

6

Might be yes. I hope they will be able to fix it, we’re a team using it daily.

I opened a thread here: https://help.nextcloud.com/t/app-no-longer-running-after-29-0-10-upgrade-on-infomaniak-one-click-upgrade/212093

Did u try to upgrade the php version used by the web hosting ? you can change it easily in Infomariak web manager panel :wink:

8

Just did :

  • Downgraded from php 8.2 to 8.1 : no change
  • Downgraded to 7.3 : This version of Nextcloud requires at least PHP 8.1 You are currently running 7.3.33. Please update your PHP version.

I’m back to 8.2

9

Not downgrade but upgrade as you need at least PHP 8.2 ou 8.3 for these versions of NC !

That is a terrible idea and for sure the best way to destroy your NC way beyond possible recovery !

Not downgrade but upgrade as you need at least PHP 8.2 ou 8.3 for these versions of NC !

I was on 8.2 already, and it is the most up to date version I could use right now on this hoster. I believe I could migrate to their new infrastructure to use php 8.3, but I’m afraid I could not go back. I may try that once I get an answer from the hoster support team.

That is a terrible idea and for sure the best way to destroy your NC way beyond possible recovery !

I made sure I had a backup before trying that. Since then I restored the backup to the state it was just before replacing the files (I’ve been using the hoster automated backup, and also I backuped the files by hand locally) .

11

Don’t forget also that you need to backup db in same to keep it with same files version or you will end up with a system unrecoverable :confused:

12

Yes, i restored the whole files and db to the state it was before trying the copy over

13

In such a case, it is probably the best to wait for the hoster’s response. Trying too many things, you can easily break things.

Don’t use such old software on publicly available servers.

14

I will wait for sure. I don’t want to break things as this cloud is daily used by a whole team. We need it up and running.

15

After insisting a bit, I got an answer from Infomaniak support :

En principe nous ne fournissons pas de support pour Nextcloud. Quoi qu’il en soit, nous avons rĂ©solu le problĂšme en supprimant un fichier qui semble ne plus ĂȘtre pris en charge sur la nouvelle version.

In principle, we do not provide support for Nextcloud. That being said, we resolved the issue by deleting a file that appears to no longer be supported in the new version.

I don’t know which file they deleted as my ticket has been automatically closed. However, my Nextcloud is now working again.

Thanks.
I’m still waiting for an answer. I insisted too, I hope I’ll get a fix too.
