This is the mxrepo.com package server for MX Linux.
A standard Debian .sources entry for the main
MX repository can be configured as:
Types: deb URIs: https://mxrepo.com/mx/repo Suites: trixie Components: main non-free
Save the repository configuration in
/etc/apt/sources.list.d/ with a
.sources extension, then update the package lists:
sudo apt update
MX Linux systems normally have the appropriate MX repository signing key and repository configuration installed already.
