Dear Maintainer,

I migrate a machine from wheezy to jessie and synaptic become unusable as it
throw an error popup with the message :
E: The value 'wheezy-backports' is invalid for APT::Default-Release as such a release is
not available in the sources ... please report.

When I close the dialog box synaptic ends.

I have found the root of that problem in /root/.synaptic/synaptic.conf where there is the line :
 DefaultDistro "wheezy-backports";

I destroy that line and all is now OK.

Regards

JP P
