[solved] Debian 10 - every key expired, cannot update keys

#1 Post by dr_Fell »

SOLVED: There was problem with system time that went crazy and was set to 2099.

Hey.
I have logged into my debian box after few months and discovered I cannot apt-get update, getting info about expired keys:

Code: Select all

Get:1 http://security.debian.org/debian-security buster/updates InRelease [65.4 kB]
Get:2 http://deb.debian.org/debian buster InRelease [121 kB]
Err:1 http://security.debian.org/debian-security buster/updates InRelease
  The following signatures were invalid: EXPKEYSIG XXXXXXXXXXXXXXXX Debian Security Archive Automatic Signing Key (9/stretch) <ftpmaster@debian.org> EXPKEYSIG XXXXXXXXXXXXXXXX Debian Security Archive Automatic Signing Key (10/buster) <ftpmaster@debian.org>
Get:3 http://deb.debian.org/debian buster-updates InRelease [51.9 kB]
Err:2 http://deb.debian.org/debian buster InRelease
  The following signatures were invalid: EXPKEYSIG...
I tried to find some solution so I tried to update keys manually, using

Code: Select all

apt-key adv --keyserver keys.gnupg.net --recv-keys <key>
But for every key on the list (all expired) I am getting something like this:

Code: Select all

gpg: key XXXXXXXXXXXXXXXX: "Debian Security Archive Automatic Signing Key (10/buster) <ftpmaster@debian.org>" not changed
gpg: Total number processed: 1
gpg:              unchanged: 1
...and the key remain unchanged.
What is strange, expired keys have future expiration date - some in 2022, some in 2027 etc...
I am stuck, don't know what to do next, appreciate any suggestions.

Michael
