I ran into several issues trying to install on Mint, since switching to Ubuntu I have not had any more compatibility errors. Your best bet is going to be Ubuntu, Lubuntu or Debian

you need to install libgomp1, but you don’t have a C++ standard library that’s new enough: it needs at least gcc 4.9, and your version of Mint is using the standard library from gcc 4.8.

Does a newer version of Mint ship with gcc 4.9? if so, upgrading to that would let you install the binary deb of zcash. If not, does your release of mint have gcc 5.x or 6.x available for it? If so, you could build it from source yourself with a newer compiler.

@anon47418038 is correct that you need to install gcc/g++ 4.9 or later. Linux Mint may be sufficiently close to Ubuntu that the instructions for upgrading gcc on Ubuntu in the 1.0 User Guide will work. (Note to others: only try this for the Ubuntu-based distribution of Mint, not for LMDE.)

I’m running into the same issue in Ubuntu 20, was on 18, upgraded to 20 and I’m still getting zcash-fetch-params: command not found. I’m following the zcash guide.

If you ran sudo apt-get install zcash and it failed (like the OP), that is why zcash-fetch-params does not exist: the zcash package isn’t installed yet. You’d need to determine why the zcash package installation failed.
