A few day ago when I was upgrading some of my servers, I notice that Zentyal was showing as being up to date in the dashboard, but there was also an alert in the dashboard that said that the server was missing an security update. When I logged into it over SSH and tried to manually install updated, I encountered the following error message.
So a few months ago, I was having trouble installing updates on one of my Ubuntu Linux servers. When I ran,
sudo apt-get upgrade I got the following error message listed below.
Originally, I planned on using Landscape to handle updating my Linux servers, but it only allows ten servers to be added before you need to upgrade to a paid license. And, after a while, I got tired of logging to my landscape server to reboot servers after updates were installed. So I setup all of my Linux servers to install updates, auto remove unnecessary dependencies and reboot the server automatically.
