Can you check the permissions of your data directory? Does the webserver has write access to /var/nc_data/updater-oct4dzqp3hji/backups/ ?

[quentinDupont]

Yep !
drwxr-x--- 3 www-data www-data 4,0K août 9 20:16 backups

And it started to create folders and files :

root:backups# ls
nextcloud-13.0.5.2
root:backups# cd nextcloud-13.0.5.2/ && ls
3rdparty apps config console.php core index.html index.php ocs-provider robots.txt settings version.php

[kesselb]

Could you check permissions and owner for /var/www/nextcloud/config/config.php.bak? I guess www-data does not have enough rights to read this file.

[quentinDupont]

Ok for config.php.bak it's owned by root indeed :
-rw-r----- 1 www-data www-data 2556 août 10 16:42 config.php
-rw-r----- 1 root root 594 août 8 21:20 config.php.bak

[quentinDupont]

Yes !
So I changed it :
sudo chown www-data:www-data config.php.bak
And try the updater that passes successfully the step 3 and every step !

Thank you !! <3

Too bad that these app (announcementcenter, onlyoffice, quota_warning, socialsharing_email, spreed) are not compatible.. yet !? 😄

[quentinDupont]

So, was it normal to have these permissions ? or I made a mistake somehow ?

[juliushaertl]

@quentinDupont The file is not supposed to be there. From the ending it might be a temporary copy of some editor that has not been removed.

Besides that this is not really a server issue. The updater cannot perform a backup if the files are not readable, so I'm closing this.
