ubuntu 的apt update 時, NO_PUBKEY error

在 ubuntu 下 apt update 顯示 error message:

W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://repo.mysql.com/apt/ubuntu focal InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 467B942D3A79BD29
W: Failed to fetch http://repo.mysql.com/apt/ubuntu/dists/focal/InRelease  The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 467B942D3A79BD29
W: Some index files failed to download. They have been ignored, or old ones used instead.

這個問題,重開機還是會一直遇到,每次下 apt update 就會顯示。解法是服用下面的指令,還有每一台電腦顯示的 key 會不一樣,要修改為你的環境裡遇顯示的 key 值。

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 467B942D3A79BD29

GPG error: The following signatures couldn’t be verified
The error tells you that your system cannot identify a certain GPG public key (PUBKEY). What you need to do is to fetch this public key in the system.
