Dear nextcloud community, I need help with a problem:
I can’t login anymore.
This started after the last nextcloud update. My windows and android apps’ session are still alive, works fine, but I can’t make any new login. The browser logins are expired. I tried to make a new user, or change the php folder and files user/group to www-data, add 770 permission, but these are not working. Also I have plenty of space on both drives (100GB+), they are not full. I’m using the /var/www/nextcloud version of NC with www-data:www-data user/group
update1: I want to reinstall php, but ubuntu 22.10 is no longer supported, so I had to upgrade to 23.04. Everything is done, works fine, except Nextcloud. still the same, can’t login, the login page just refreshes after trying to login.
Also I tried sudo -u www-data php /var/www/nextcloud/occ maintenance:repair , not working.
There are no files created in /var/lib/php/sessions
I set this folder to use by php in php’s php.ini files (both php/8.1/apache2 and /cli folders, but I think this should be the default. It worked befor the nc update)
update2: if I chmod 777 -R /var/lib/php/sessions/ then it WORKS!! What is the problem then? It looks like it is something permission thing. Now there are files in the session folder, with www-data:www-data ownership! I think I shouldnt live with a chmod 777 session folder. it should be 770? So what can I do to make it work again?
update3: OK, the folder itself is 777, but the session files created are -rw-------. So it looks it’s safe, right? stuuuupid linux
