I know there's a related thread over at OMV 1.18 CRON-APT Error: The value 'stable' is invalid for APT::Default-Release as such a release is not available in the sources but as pretty much still a noob, I wanted to make sure I'm doing the right things.
Right now, I am running 1.17 (Krazilec) with a few OMV Extras. If I remember correctly, I had to install a backported kernel, due to a relatively new mainboard. For Details please see attached files.
So, if I understand correctly, I go and dig through the apt.conf.d directory and and everywhere I find anything like release: "stable" I change it into "wheezy" - correct?
