apt-get update error

[olijan71]

Hello,

I have a problem when running . /bashme.sh.

I’m on the Rpitcv3_1.12 release.

When ordering apt-get update I get the following error message:
W: GPG error: http://ftp.us.debian.org/debian sid Inrelease: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY 04EE7237B7D453EC NO_PUBKEY 648ACFD622F3D138

I tried the gpg command:
gpg --keyserver pgpkeys.mit.edu --recv-key 04EE7237B7D453EC

I have the following error message:
gpg: connecting dirmngr at '/run/user/0/gnupg/S.dirmngr' failed: IPC connect call failed
gpg: keyserver receive failed: No dirmngr

Thanks for your help.
