ArchLinux-How to troubleshoot key issues

There are times when we add third-party libraries when using arch:

gpg: connecting dirmngr at ‘/root/.gnupg/S.dirmngr‘ failed: IPC connect call failed gpg: keyserver receive failed: No dirmngr ==> ERROR: Remote key not fetched correctly from keyserver.When trying to run pacman-key -r CC1D2606 && pacman-key --lsign-key CC1D2606Please do sudo -i dirmngr < /dev/null this will start up dirmngr properly and allow the remote key to be fetched.

This is from a snapshot of Baidu stripped down, I also do not understand this magic key configuration. (Looks like the input method problem-= inexplicable wonderful ...)

It would be nice to do this anyway.

sudo -i dirmngr < /dev/null

To be precise, the purpose of this command is to get the Dirmngr to start correctly.

How did I solve the problem?

export LANG=en_USThen search in English and finally get the answer.
