I'm trying install processing but i get the error java: error while loading shared libraries: libjli.so: cannot open shared object file: No such file or directory. I already re-install java from many tutorial but i get the same, could someone help me?
This is a reported issue at https://github.com/processing/processing/issues/5111 try to download an earlier version while this is not fixed.
Processing 3.3.3 should work fine.
UPDATE: Processing 3.3.5 is out and it's working fine on Ubuntu.
