Hi, My setup is Ubuntu 11.04 host with multiple Debian Sqeeze and Wheezy nodes. Not all of my vm's have aptitude installed so if I try to do an OS upgrade from ISPConfig control panel I get errors. Do OS-Update at remote server This Action does a 'aptitude -y upgrade' at your selected server. USE THIS AT YOUR OWN RISK! What is recommended here? Should I install aptitude on every node or can I change the command somewhere in ISPConfig configuration. Also the exact distro is often not correctly reported in the ISPConfig interface - this doesn't bother me much at all but I would be interested in fixing it if I could. The Ubuntu host is reported as being a Debian Sqeeze install and the Debian Wheezy (testing) node is being reported as unknown. Thank you for any help.
