If I try to stop (then restart) MySQL service :
Stopping MariaDB 10.5.15 database server... sept. 09 19:36:04 yunohost.lapineige.fr mariadbd[27855]: 2022-09-09 19:36:04 0 [Warning] /usr/sbin/mariadbd: Thread 31 (user : 'nextcloud') did not exit
Soooo… Nextcloud user got deleted ???
Should I try to regenerate mysql conf ?
edit : stopping the serviced failed (it timed out). Full log : sept. 09 19:36:04 mariadbd[27855]: 2022-09-09 19:36:04 0 [Warning] /usr/sbin/ma - Pastebin.com
But I can start it ! (Nextcloud still fails)
