我正在尝试从 Ubuntu 18.04.6 LTS 升级。运行
sudo apt update失败并显示消息The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 76F1A20FF987672F。问题是这个密钥做存在。sudo apt-key list返回
pub rsa3072 2018-12-10 [SC]
D43F 6401 4536 9C51 D786 DDEA 76F1 A20F F987 672F
uid [ unknown] WineHQ packages <[email protected]>
我甚至尝试删除并重新创建密钥。完整输出来自sudo apt update
