Ubuntuaptupgrade出现error"NO_PUBKEY"的解决
Ubuntu apt upgrade出现错误:
W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://apt.postgresql.org/pub/repos/apt bionic-pgdg InRelease: The following signatures couldn"t be verified because the public key is not available: NO_PUBKEY 7FCC7D46ACCC4CF8W: Failed to fetch http://apt.postgresql.org/pub/repos/apt/dists/bionic-pgdg/InRelease The following signatures couldn"t be verified because the public key is not available: NO_PUBKEY 7FCC7D46ACCC4CF8
执行
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys <PUBKEY>
其中 <PUBKEY>
是缺失的 public key for repository。
我这里为:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 7FCC7D46ACCC4CF8
然后,再update:
sudo apt-get update
可选方法:
sudo gpg --keyserver pgpkeys.mit.edu --recv-key <PUBKEY>sudo gpg -a --export <PUBKEY> | sudo apt-key add -
sudo apt-get update
注意:当导入 key(如使用 apt-key
) 就意味着告诉系统你信任这个签名软件。除非确认,不要使用这个导入的方法。
