Docker build with - Can't check signature: No public Key

General questions
1

When hitting the below in my docker build:

gpg --batch --keyserver keyserver.ubuntu.com --recv-keys 814E346FA01A20DBB04B6807B5DBD5925590A237; \
gpg --batch --verify matomo.tar.gz.asc matomo.tar.gz; \

I’m getting:

gpg: Can't check signature: No public key

This worked the first time I build but now with an updated version it fails. Can anyone provide direction to the fix? I’m assuming it’s an updated key but where to get that.

Any idea on how, to find GPG signing Public Key ID ?

Now in 2026 I have the same problem :thinking:

Thanks for the update. Good to know that Matomo 5.1.2 resolves the compatibility issues with MariaDB 11.5.2. Hopefully this also helps address the Docker build signature key issue.
