Subsonic in DietPi

Subsonic appears to have been removed from the DietPi install menu. Previous screen shots show it as number 33 and 34 under optimized software, but now the menu jumps from 32 to 35 in Media Systems.

Would like to install Subsonic to run a music server on my Raspberry Pi.

When I try to install from the terminal, I get an error that subsonic-6.1.5.deb is not a Debian format archive.

(confirmed file downloaded)

sudo dpkg -i subsonic-6.1.5.deb

Recommendations on how to install?
