Problems running discoSnp++ sample example

Question

[tsi.insilico]

Hello all, I downloaded discoSnp++ on ubuntu 22 -04 running on oracle vm.I downloaded and extracted the linux binaries from the releases tab on github and tried to run ./run_discoSnp++.sh -r fof.txt -T after following all the preceding steps. I have repeatedly had the following responses:

./run_discoSnp++.sh: line 69: python: command not found
cat: fof.txt: No such file  or directory
./run_discoSnp++.sh: line 503: /bin/read_file_names: No such file or directory

What could be the problem? Thank you,any help will be highly appreciated.
