Wheezy Invalid Key for Backports? [Solved]

[buntunub]

Code: Select all

A error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://http.debian.net wheezy-backports Release

Huh?

Code: Select all

Debian Archive Automatic Signing Key (6.0/squeeze) <ftpmaster@debian.org>

W: Failed to fetch http://http.debian.net/debian/dists/wheezy-backports/Release  

W: Some index files failed to download. They have been ignored, or old ones used instead.

Hmm. Seems that during the netinst, it automatically inserted an incorrect source for wheezy-backports.

Code: Select all

deb http://http.debian.net/debian/ wheezy-backports main

This is incorrect. The proper source can be found at http://backports.debian.org/

I simply updated it to the source listed on that site and the error went away. Prior to that I had not touched my sources.list after install.

if it still does not work for you,
this one works for me:

try running:

Code: Select all

sudo aptitude install debian-archive-keyring

first
you may also try to change your source-list to https.

for example, in

Code: Select all

/etc/apt/sources.list.d/wheezy-backports-main.list

,
instead of

Code: Select all

deb http://http.debian.net/debian wheezy-backports main

,
edit it, and replace with:

Code: Select all

deb https://deb.debian.org/debian wheezy-backports main
deb https://deb.debian.org/debian stable main
deb https://deb.debian.org/debian-security stable/updates main

run

Code: Select all

sudo apt-get update

, it should work now.

Apart from this being a 4 year old thread,

Code: Select all

deb https://deb.debian.org/debian wheezy-backports main
deb https://deb.debian.org/debian stable main
deb https://deb.debian.org/debian-security stable/updates main 

This is really bad advice, mixing Debian 7 (wheezy) with the
current stable Debian, is NOT a good idea.
