查詢過期的key
sudo apt-key list | grep "expired: "
再更新這個key ，2007B954是查詢出來的KEY
sudo apt-key adv --keyserver keys.gnupg.net --recv-keys 2007B954
key server可能不一定全部通用
例子
giantbranch@ubuntu:~$ sudo apt-key list | grep "expired: "
pub 4096R/2007B954 2012-12-06 [expired: 2019-09-02]
pub 4096R/473041FA 2010-08-27 [expired: 2018-03-05]
pub 4096R/B98321F9 2010-08-07 [expired: 2017-08-05]
pub 4096R/65FFB764 2012-05-08 [expired: 2019-05-07]
具體例子
giantbranch@ubuntu:~$ sudo apt-key adv --keyserver keys.gnupg.net --recv-keys 2007B954
Executing: /tmp/tmp.xtyH1a64lT/gpg.1.sh --keyserver
keys.gnupg.net
--recv-keys
2007B954
gpg: requesting key 2007B954 from hkp server keys.gnupg.net
gpg: key 2007B954: "Metasploit <[email protected]>" 9 new signatures
gpg: Total number processed: 1
gpg: new signatures: 9
或者一鍵ko
sudo apt-key list | grep "expired: " | sed -ne 's|pub .*/\([^ ]*\) .*|\1|gp' | xargs -n1 sudo apt-key adv --keyserver keys.gnupg.net --recv-keys
