i have a problem with nextcloud update. My nc yesterday updated to version 18 snap and i wanted to revert it because i had problems with some apps. I do a revert but i realized that i haved backup anything…the problem is that the files menu does not work from web browser. The filles are okey and i can access them from gallery (and of course from ftp) . In mobile up i can see files and folders and everything seems okey.
i tried to perform files scan but nothing and i edited data directory from config but nothing so this is not the problem.
after typing this i see that
sudo -u www-data php /var/www/nextcloud/occ files:scan
An unhandled exception has been thrown:
Doctrine\DBAL\DBALException: Failed to connect to the database: An exception occurred in driver: SQLSTATE  could not connect to server: Connection refused
Is the server running on host “localhost” (127.0.0.1) and accepting
TCP/IP connections on port 5432? in /var/www/nextcloud/lib/private/DB/Connection.php:68
#0 /var/www/nextcloud/3rdparty/doctrine/dbal/lib/Doctrine/DBAL/Connection.php(420): OC\DB\Connection->connect()
#1 /var/www/nextcloud/3rdparty/doctrine/dbal/lib/Doctrine/DBAL/Connection.php(380): Doctrine\DBAL\Connection->getDatabasePlatformVersion()
(and some more)
my question is how can i fix this problem ?
(even if an update can solve it)
thank you very much!
