okass 在版块 Linux平台 中发起了话题 ubuntu apt-get 出现NO_PUBKEY的解决方案 3年, 1个月前
sudo apt-get update
报错如下：
The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY F42ED6FBAB17C654
Fetched 4,678 B in 2s (1,902 B/s)
Reading package lists… Done

apt-key adv –keyserver keyserver.ubuntu.com –recv-keys xxx %xxx替换成报错的F42ED6FBAB17C654
apt-key adv –[两短横]recv-keys –[两短横]keyserver keyserver.ubuntu.com xxx
再进行sudo apt-get update发现问题解决
