I've recently been amending my sources.list to focus on Unstable. Now, when I try to run Synaptic, I get this error message:
"The value 'testing' is invalid for APT::Default-Release as such a release is not available in the sources"
This seems to imply that Testing is set as the default release. But I can't find any file in /etc/apt/apt.conf.d where that is specified.
There was no file apt.conf in /etc, so I created one with this content:
But I still get the same error message when I try to run Synaptic. Can anyone point me in the right direction, please? Thanks very much.
