Rooting acer liquid mini with Ubuntu?
Super One Click is written in C#. You need Mono to run it under Linux and other Non-Windows platforms. You can check your Ubuntu Package Manager for Mono or download it from here.

The XDA-Forum-Link also has a link to a detailed description on how to make it work under Linux.

I have never personally used it on Linux, but once the program is up and running, it should be very self explanatory.
