I installed OTRS via terminal in Ubuntu 10.04. I used the "apt-get install otrs2" and worked as planned. But how can I upgrade to 2.4.9. This is running in a test environment and there has been no changes or add-ons to the environment. A simple "todo" would be greatly appreciated. Or is there a different method using the apt-get to install 2.4.9 instead of 2.4.7.
