APT 1.6 and newer failed to verify InRelease files that were retrieved
as a fallback from one mirror to another when using the mirror:// method.
As the mirror method can thus not be trusted, it is suggested to replace
use of the mirror method in sources.list files with the standard http
method before upgrading to a fixed version.
