WSJT-X 2.0 requires a modified Hamlib, and some other libraries. There is a published version that is supposed to work with Debian Stretch and a Ubuntu 18.04 LTS version. I couldn't get the Stretch version to work, but the 18 LTS version did for me. The 18.04 version might work on Mint 18. The 2.0 version for Opensuse Leap 42.3 just came out a couple of days ago. ... sorry I can't speak directly to Mint.
