When APT complains about security.debian.org

Shortly after responding to Jonathan Groll on the CLUG’s mailing list about BADSIG errors. I’ve had the pleasure of experiencing it again.

pants:~$ sudo aptitude update
[...]
W: GPG error: http://security.debian.org lenny/updates Release: The following signatures were invalid: BADSIG A70DAF536070D3A1 Debian Archive Automatic Signing Key (4.0/etch)
W: You may want to run apt-get update to correct these problems

I often have to remind myself to use Acquire::http::No-Cache=True when my machines are behind a SAIX proxy.

pants:~$ sudo aptitude -o Acquire::http::No-Cache=True update
[...]
it http://security.debian.org lenny/updates/non-free Sources
Fetched 14B in 12s (1B/s)
Reading package lists... Done

I should probably just put the below code in my apt.conf or in a file in apt.conf.d to safe me from future occurrences.

Acquire
{
  http
  {
    No-Cache "true";
  };
};
