[Nextcloud 14] Internal Server Error

[untilbit]

I have installed Nextcloud and was working for a few hours and then it's showing an Internal Server Error. I have checked the server log and haven't found what's the problem.

BTW, I have other apps working fine. The issue is just with nextcloud 14.

Client Error

Your server log is incomplete. Can you please post more content of your server log?
Have a look at it with "less" or "cat" and not with "vi".

And check first that your database is reachable if you use MySQL or PostgreSQL.

This also happens for me, during first time LDAP login. The error logs are:

Looks like

server/apps/dav/lib/CardDAV/SyncService.php

Line 268 in e22d15c

$name = $user->getBackendClassName();

$user is null ?

GitMate.io thinks possibly related issues are #6839 (Nextcloud got internal Server error after update APP:OnlyOFFICE, need to remove this APP completely), #2741 (Calendar app: internal server error after upgrading to Nextcloud 11), #7622 (NextCloud Server Listener ), #8326 (Internal Server Error (Template not found) when loading Calendar after upgrade to Nextcloud 13.x), and #5056 (nextcloud 12 upgrade error).

I'm pretty sure I stumbled across this issue this morning. I had added a user through the IMAP verification, and then it disappeared from the users list and when I try logging in to the account, it errors. There is no sign of the account in the users list or under occ user:info [username].

Error in log:

Ok, first of all @untilbit's error report is database related:

Doctrine\DBAL\Ex

DBAL = database abstraction layer.
Unfortunatly this isn't the complete line of the error message.

[timm2k]

@nebulade and @nickdbush are you sure you have a clean update running and apps are up-to-date? I had a similar error with an unclean manual update where files of NC13 and NC14 were mixed up. I didn't delete all NC13 files before I've put NC14 into place.

[ngmdat]

i have the same problem as the first reportp. the nextcloud-bot set [bug] lable to this issue, then how to recover my nextcloud server ?

[ArnaudTA]

Same error here ! I use the docker image. I manually activated the ldap module for php in container, i don't know if it's helpful. The installation is fresh.
Thanks for your work !

[untilbit]

I'hva finally solved this issue by addming my user to the group www-data.

No updates solved this.
The issue is that I use SQLITE as databse and a file changes owner to my user and later nextcloud could not read it.

[kesselb]

Glad you solved it

[untilbit]

It fixed the issue only temporarily, now I get the error again.

[jospoortvliet]

Ok, but it is a database access/ownership issue, correct? Make sure the owner of the files is the same as your webserver, or at least the web server has read/write access. Check ls -la output in the data folder, it shows you the access rights on the file.

Find further help on help.nextcloud.com, please, as github isn't meant as support platform 🤺

Yo lo arreglé habilitando los permisos de escritura, solo estaban habilitados los de lectura
