Could not restore nextcloud: An error occured inside the app restore scrip

but now I have no nextcloud at all…

My upgrade failed because of an incompatible app. But then the restoration also is failing because of another app: Memories. It is now stuck in the terminal during mysql database restoration:
Info: [#####++…] > Restoring the MySQL database…

^^^^^^^^^^^^^^^^^^^^

How do I continue? Should I stop the process?

I canceled using ctrl-c and then it rolled back the restoration so that Nextcloud was cleanly uninstalled. I then started the restoration manually and it worked! At least I have my old Nexcloud back and running now.

I got an error upgrading to NC 33, saying that the Memories app is incompatible with NC 33. The script then tried to restore from pre-upgrade backup, but failed, without a clear error at the end, but seemingly stuck in a loop. I then tried to manually restore from backup via CLI using `sudo yunohost backup restore nextcloud-pre-upgrade1 --apps nextcloud`. This failed as well, again without an error, but seemingly stuck. Logs attached. Now trying restore from webadmin, but it is still working.

Indeed, the Memories app does not appear to be compatible with NC 33.

Disable Memories app

cd /var/www/nextcloud

sudo -u nextcloud php8.3 occ app:disable memories

These are the final lines in the log of the restore operation:

2026-04-01 03:45:07,904: DEBUG - + find /home/yunohost.app/nextcloud/data/ -type d -print0
2026-04-01 03:45:08,230: DEBUG - + xargs -r0 chmod 0750

It seems stuck on changing the permissions. And there is a defunct `chmod` process

root 2231828 1.0 0.0 7416 2952 ? D 03:45 1:41 find /home/yunohost.app/nextcloud/data/ -type d -print0
root 2231829 0.0 0.0 5732 2020 ? S 03:45 0:01 xargs -r0 chmod 0750
root 2245616 0.0 0.0 0 0 ? Z 06:29 0:00 [chmod]

Should I kill the restore? Or let it continue?

EDIT: apparently the restore finished succesfully in the end:

started_at: 2026-03-31 20:46:47.083901
started_by: admin
success: true
yunohost_version: 12.1.39

But now there is another issue:

sudo -u www-data php /var/www/nextcloud/occ status
Cannot write into “config” directory!
This can usually be fixed by giving the web server write access to the config directory.

But, if you prefer to keep config.php file read only, set the option “config_is_read_only” to true in it.
See Configuration Parameters — Nextcloud latest Administration Manual latest documentation
{“reqId”:“Xx7I7Uiaz4ohTjLruJWY”,“level”:3,“time”:“2026-04-01T07:10:21+00:00”,“remoteAddr”:“”,“user”:“–”,“app”:“PHP”,“method”:“”,“url”:“–”,“scriptName”:“/var/www/nextcloud/occ”,“message”:“fopen(/var/www/nextcloud/config/config.php): Failed to open stream: Permission denied at /var/www/nextcloud/lib/private/Config.php#210”,“userAgent”:“–”,“version”:“”,“occ_command”:[“/var/www/nextcloud/occ”,“status”],“data”:{“app”:“PHP”}}

EDIT2:
I fixed the permissions, and set the “config_is_read_only” to true in the config file, and now it’s working again!

I can’t upgrade either.

There is lots of this and then it fails.

SOLVED. Totally forgot I had Memories plugin installed.
