Some m23 servers seem to be unable to install or update m23 from the package repository on the SourceForge mirrors currently. The error is shows as "Hash Sum mismatch" during apt-get update. A new repository was created to solve the problem.

Edit the /etc/apt/sources.list on your m23 server, if you get this error too. Delete all lines containing sourceforge.net. Add a new line with deb http://m23inst.goos-habermann.de ./ at the end of the file.
Update the package index via apt-get update. For an update use the command apt-get dist-upgrade. For installation of m23 use apt-get install m23.
