nginx repo key expired [debian]

[skurudo]

When we make "apt-get update" we can get error like this:

Code: Select all

W: A error occurred during the signature verification. 
The repository is not updated and the previous index files will be used. 
GPG error: http://nginx.org wheezy Release: The following signatures were invalid: KEYEXPIRED 1471427554

W: Failed to fetch http://nginx.org/packages/debian/dists/wheezy/Release
W: Some index files failed to download. They have been ignored, or old ones used instead.

Command to see what exactly expired:

Code: Select all

apt-key list | grep "expired:"

Output:

Code: Select all

pub   2048R/7BD9BF62 2011-08-19 [expired: 2016-08-17]

Update what's expired:

Code: Select all

apt-key adv --recv-keys --keyserver keys.gnupg.net 7BD9BF62

If you receive:

gpg: requesting key 7BD9BF62 from hkp server keys.gnupg.net
gpg: keyserver timed out
gpg: keyserver receive failed: keyserver error

Just disable CSF (csf -x) then try again, and re-enable CSF (csf -e)
