Ever vigilant TurnKey community member, John Carver (aka Dude4Linux), has again bought to our attention an issue worth addressing. In a recent bug report John notes that the Debian old-old-stable (7/Wheezy) and old-stable (8/Jessie) backports apt repositories have now been archived.

Ideally v13.x & v14.x TurnKey users are advised to update/migrate their data to the relevant current v15.x release of their appliance. If you need a hand with that, please do not hesitate to start a new thread on the forums (new threads require a free website user account; if you have any troubles posting please let us know). But if that's not an option right now, to avoid errors jamming up your apt logs, TurnKey v13.x and v14.x users are advised to make an adjustment to their servers.
