12.0.0 to 12.0.1 via Updater Stable channel

Check for write permissions
The following places can not be written to:

Does this fix that issue?

chown -R www-data:www-data /var/www/nextcloud

This is the result of using the Updater within Nextcloud, “Stable” update channel.

Thank you.


It depends if you changed the owner of .htaccess previously to root and on your current file permissions.
Make sure .htaccess and other files are owned by www-data and that write permissions are set for the owner.

Check with
ls -la /var/www/nextcloud

If any file or folder is listed with
-rw-r**** root root

then run
chown -R www-data:www-data /var/www/nextcloud

If furthermore .htaccess only has read rights (r–r--r-- or r–r-----) then you also need to run:
chmod 640 /var/www/nextcloud/.htaccess
