libltr.so.0 ... not working on newer distros.. Ubuntu 20.10

[AndKe]

bin$ ./ltr_gui 
./ltr_gui: error while loading shared libraries: libltr.so.0: cannot open shared object file: No such file or directory

Could you please fix it?

I'm having the exact same problem

I finally solved it! You have to extract the universal package somewhere within /opt

@uglyDwarf - please update with the suggested fix

I have Linux Mint 19.3, which indeed is an Ubuntu 18 but I'm experiencing the same error. I uncompressed the 64 bit universal package into a folder under /opt.

In the screenshot you can see that even the suggested command 'ldd * | grep 'not found' | sort -u' notifies two linuxtrack's libraries as not found.
