I installed the 7.3 Demo on a newly installed and updated Linux Mint Debian at home this morning.
Linux Mint Debian is a rolling distribution. You are always current. The operator interface is close to Linux Mint.
I installed and updated the 64 bit version. Sun JRE 1.6 26 was already there. The kernel is Linux 3.0.
The 7.3 64 bit install went without a hitch.
Thought you’d like to know.
