I've tried to apply only the Library updates shown in the screenshot, and this process never ended. Instead, now I can no longer access Webuzo on any of its ports, nor phpmyadmin.
Unable to connect Firefox can’t establish a connection to the server at 31.220.*.*:2004.
The VPS support will return tomorrow, but I'd like to get some help here because this is very worrying. The hosted sites are online and the SSH access works fine.
