Ubuntu - expire gpg key

When we have a problem with expire gpg key

 #check key

apt-key list                         à example - expired: 2000-01-01

#download new key from repository server (check proxy server)

10.223.120.3:8000 - test

10.223.248.3:8000 - production

(proxy: /etc/apt/apt.conf)

wget -e use_proxy=yes -e http_proxy=http://10.10.10.31:3935 http://reposerver.com/pub/gpg.key

#add new key 

apt-key add gpg.key

#check key

apt-key list

# For error:

E: Repository 'http://landscape.oam-sa.mn.de.tmo/repository/standalone/ubuntu bionic InRelease' changed its 'Suite' value from '' to 'bionic'

N: This must be accepted explicitly before updates for this repository can be applied. See apt-secure(8) manpage for details.

# Fix and use new gpg key

apt-get update --allow-releaseinfo-change
