Comment 12 for bug 1503979

Note that on a trusty host I have where ubuntu-support-status doesn't throw a traceback, the following files exist:

-rw-r--r-- 1 root root 64441 Oct 22 23:53 /var/lib/apt/lists/ubuntu-mirror.nxnw.org_ubuntu_dists_trusty-security_InRelease
-rw-r--r-- 1 root root 63459 Oct 1 23:28 /var/lib/apt/lists/ubuntu-mirror.nxnw.org_ubuntu_dists_trusty-security_Release

The latter being outdated with respect to the former. apt should probably be cleaning these out.
