![公钥混乱吗?](https://linux22.com/image/974389/%E5%85%AC%E9%92%A5%E6%B7%B7%E4%B9%B1%E5%90%97%EF%BC%9F.png)
当我更新系统时出现此错误:
W: GPG error: http://ppa.launchpad.net trusty Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 241FE6973B765FAE
有没有什么办法可以解决这个问题?

使用以下命令导入公钥。然后更新:
sudo apt-key adv --recv-key --keyserver keyserver.ubuntu.com 241FE6973B765FAE
