OTRS works as expected on a Mandrake system, at least when using release 9.1 or 9.2. As we do not provide a ready-to-use RPM right now, you will have to follow the documentational steps for a manual installation using the tarball.
Before considering installing OTRS on a Mandrake system, you are strongly encouraged to use Mandrake's software package management to update your system to the most recent available version. You may find a convenient GUI in Mandrake's Control Center, or issue these commands as the superuser via the command line:
shell:~ # urpmi.update --update --auto --auto-select shell:~ # urpmi --update --auto-select |
shell:~ # urpmi.addmedia update_source ftp://ftp.gwdg.de/pub/linux/mandrake/updates/<rel>/RPMS |
