synaptic doesn't start properly in Wheezy
Originally created by @anonym on #7055 (Redmine)
I get the following fatal error immediately after the GUI has loaded:
E: The value 'wheezy' is invalid for APT::Default-Release as such a release is not available in the sources
E: _cache->open() failed, please report.
Hence the apt.feature
automated test fails without a stupid workaround
(commit 4c7beba).
