如何修复 apt-key gpg: keyserver receive failed: No dirmngr
问题：
你想使用类似这样的命令通过 apt-key 添加仓库签名密钥
recv_key.sh
sudo apt-key adv --keyserver hkp://keys.gnupg.net --recv-key E0FF663E但你收到类似这样的错误消息：
gpg_error.txt
Executing: /tmp/apt-key-gpghome.qn3065We9J/gpg.1.sh --keyserver hkp://keys.gnupg.net --recv-key E0EE663E
gpg: failed to start the dirmngr '/usr/bin/dirmngr': No such file or directory
gpg: connecting dirmngr at '/tmp/apt-key-gpghome.qn3065We9J/S.dirmngr' failed: No such file or directory
gpg: keyserver receive failed: No dirmngr解决方案
install_dirmngr.sh
sudo apt install dirmngr然后重试 apt-key 命令
