Hi all, @mrmarkuz reported a bug of HotSync package. I’m going to fix it. This is the message:
"I found that Hotsync produces an error when Mattermost is installed.
Mattermost uses postgresql12 now but hotsync still wants to backup the old database from a wrong port.
In /etc/hotsync.d/mattermost.sh line 34 should look like this to respect the newer database server and to make it work again: /usr/bin/su - postgres -c "scl enable rh-postgresql12 -- pg_dump --port 55434 mattermost > /var/lib/nethserver/mattermost/backup/mattermost.sql""
