The following signatures couldn't be verified because the public key is not available 解决方法
今天试图把 deepin 的软件源加到我到 Ubuntu 16.04 中去。
在 deepin wiki 上看到一个教程。
在 /etc/apt/sources.list
中加上 deepin 的软件源之后,执行 sudo apt update
报错:
Err:3 http://packages.deepin.com/deepin unstable InRelease
The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 425956BB3E31DF51
搜索一番,发现一个办法
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 425956BB3E31DF51
再次执行 sudo apt update
就不会报错了。
