“由于公钥不可用，无法验证以下签名：NO_PUBKEY 23F3D4EA75716059”

Question

我尝试更新 Debian，但收到以下错误消息：

% sudo aptitude update

它似乎与我的以下行有关/etc/apt/sources.list.d/github-cli.list：

deb [arch=amd64 signed-by=/usr/share/keyrings/githubcli-archive-keyring.gpg] https://cli.github.com/packages stable main

那么，如何解决这个签名错误呢？

那么，如何解决这个签名错误呢？

公钥已于 2022 年 9 月 2 日过期。 这里提供了有关如何安装新证书的说明：

curl -fsSL https://cli.github.com/packages/githubcli-archive-keyring.gpg | sudo dd of=/usr/share/keyrings/githubcli-archive-keyring.gpg \
&& sudo chmod go+r /usr/share/keyrings/githubcli-archive-keyring.gpg \
&& echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/githubcli-archive-keyring.gpg] https://cli.github.com/packages stable main" | sudo tee /etc/apt/sources.list.d/github-cli.list > /dev/null \
&& sudo apt update \
&& sudo apt install gh -y
