For this error:
" sudo: ./cube-server-installer : command not found"
This error will only occur if the sudo app failed to find the cube-server-installer.
Could you check if the cube-server-installer (exact filename) exists? You said also earlier that a file "cube-server-iinstaller" (double 'i' in installer word) has been extracted. I think this mispelled word is the cause of the error. Try to rename the file and do the command again.
