synaptic disabled by bad apt:default-release value

newbiesforever · 09-19-2013, 03:02 PM

I presently can't use Synaptic, though I seem able to do anything with terminal apt-get. Synaptic says:

Code:

E: The value 'stable' is invalid for APT::Default-Release as such a release is not available in the sources
E: _cache->open() failed, please report.

This looks like possibly a bad value in one of the files in /etc/apt, but I suppose not, because I can't find any file that says anything like "stable" for "Default-Release" and I haven't edited anything in those files recently anyway. (No--correction: I have, but through Synaptic. I think I changed the preferred release from "highest" to "stable" after getting several buggy updates from testing.) So how do I fix this? Might it be because Debian has renamed some of their repositories (I don't know what they're doing--maybe stable has become oldstable or something, for all I know) and my information needs updating?

I've found that I can solve this by running apt-get update in a terminal before running Synaptic, and then changing the preferred release in Synaptic to "wheezy" rather than "stable"; but it still shouldn't happen at all. Wasn't before.

Open file /etc/apt/apt.conf
Can you see the line

Code:

APT::Default-Release “testing”;

Comment the line using // at starting of the line.

Now try again.

I'm sure I recognize that line, but oddly, it's missing from the file. The entire contents of the file are:

Code:

// Recommends are as of now still abused in many packages
APT::Install-Recommends "0";
APT::Install-Suggests "0";

I have no idea what happened to the line. So should I write it in, substituting whatever release I want for "testing"?
