Some time ago I triggered upgrade from Kubuntu 15.10 to 16.04 and it failed (I forgot why and with what message). When I issued sudo do-release-upgrade it failed with message:

E: The value 'wily' is invalid for APT::Default-Release as such a release is not available in the sources

Full log-output (with errors): -> paste.ubuntu.com

Then I tried sudo apt-get autoclean but it failed with similar message. So I decided to revert /etc/apt/sources.list with command sudo cp /etc/apt/sources.list.distUpgrade /etc/apt/sources.list, then I did sudo apt-get update and repeated release upgrade. Unfortunately it failed with the same result...

How should I fix this?

Error E: The value 'wily' is invalid for APT::Default-Release as such a release is not available in the sources occured during repositories reconfiguration. It was caused by content of /etc/apt/apt.conf where wily was set instead of xenial.

I changed this file's content to APT::Default-Release "xenial"; and next upgrade attempt finished successfully.
