[Synaptic-devel] APT::Default-Release 'experimental'

[Jaromír Mikeš]

Hello all,

I have this error message on start up synaptic after normal regular
upgrading in testing.
I didn't make any changes on settings.

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

After closing Error message window synaptic is closed too.

File apt.conf doesn't exist on my system ... so I have no idea where
else I can change this.

Thank you for any help.
