I have bought a new server and installed Nethserver 7.3.1611 on it. After the initial installation some updates came in, which were also installed. Since then, I do not get any updates anymore when I enter yum update. Nextcloud 12, Roundcube Mail and the virus scanner from Stephdl are running on the server. The latest update is from August 12th. Is the behavior normal because there was no more updates since then, or did I have a bug in the system?
