GPG error with http://volatile.debian.org : 'The following signatures were invalid: NODATA 1 NODATA 2' I am currently trying to add a new repository to apt-get but it is not working. I'm adding it like this: deb wheezy/volatile non-free Then I get this error: Get:11 wheezy/volatile Release [7626 B] Ign wheezy/volatile Release E: GPG error: wheezy/volatile Release: The following signatures were invalid: NODATA 1 NODATA 2 My system is running on Debian 7. How could I fix this?

Volatile was discontinued with Squeeze; the replacement is _suite_ -updates (in your case, wheezy-updates) on the standard mirrors:


deb wheezy-updates main


You can add `contrib non-free` if necessary.
