Package: apt-cacher
Version: 1.7.6
Severity: normal
Dear Maintainer,
It appears that when an InRelease file disappears (as seems to have
happened to wheezy following its release), apt-cacher returns the old file
instead, albeit with the 404 message body overwriting the beginning of the
file:

While I unfortunately didn't have debugging enabled two weeks ago, I *can*
show you what error.log looks like fetching the file now:

The result of this is expired release file errors from every apt-get
update since wheezy's release.
A glance at the code around line 770 suggests that all errors result in the
cached file being returned (and an 'OFFLINE' status). I'm not convinced
that this is a good idea, at least with 404s. :P
I suspect the returned cached file being contaminated by the 404 response
body is a separate bug...
