After some issues on the latest Mixxx version like no hability to run properly... i share the only option out there.
the previous version in bin file format.
i pickup from portablelinuxapps on sorceforge.
in my linux lite i was able to run directly through a custom launcher on panel.
only you need to do is check on proprieties the option to run as executable
and launch through terminal or through a custom launcher
rename the file to Mixxx
run the command ./Mixxx
in the first run you have to pickup the songs directory and change skin theme according to your screen resolution on preferences/interface
