Install yum Mono package

I’m trying to install the mono package on almalinux 9 but I can’t contact the GPG keyserver. Has anyone had this problem before? how can i fix it?

The keyserver may have been having issues. I just installed mono-core on a 9.1 install without any issues. I’d say try it again.


I tried again but still error. which keyserver and repository did you use? signature not supported. Hash algorithm SHA1 not available. and with can’t resolve the host

Make sure epel-release is installed, then install mono-core.

sudo dnf install mono-core
