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

我尝试更新 Debian 但收到以下错误消息：

% sudo aptitude update

这似乎与我的以下几行相关/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，如何修复此签名错误？

那么，如何修复此签名错误？

公钥将于2022年9月2日到期。 这提供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

我遇到了同样的错误，可以通过更新时钟来解决这个问题

sudo hwclock --hctosys

然后

sudo apt update

如果 PC 处于睡眠/休眠状态，则可能会导致硬件时钟不同步（我在 WSL2 上）。这导致 Linux 看到错误的时间，对于较新的存储库的更新来说太早了。
