Because it is available via PPA, installing VeraCrypt on Ubuntu 15.04, Ubuntu 14.10, Ubuntu 14.04 and derivative systems is easy. All you have to do is add the ppa to your system, update the local repository index and install the veracrypt package. Like this:
$ sudo add-apt-repository ppa:unit193/encryption
$ sudo apt-get update
$ sudo apt-get install veracrypt
Optional, to remove veracrypt, do:
$ sudo apt-get remove veracrypt
