Error on Ubuntu

[rakkarage]

i tried this a few weeks ago and it worked.
tried new version and get an error:

/tmp/.mount_UnityHs6dwuG/unityhub: error while loading shared libraries: libgtk-x11-2.0.so.0: cannot open shared object file: No such file or directory

Please & thanks

i tried it from live usb and it installed fine
i have this lib on my system but am not sure why UnityHub cannot deal
