Can someone help me install Bitconnect Wallet (tar file) on Ubuntu 14.04?

I tried to install Bitconnect Wallet (tar file) on my Ubuntu 14.04, but it is not working. I followed some instructions on a YouTube video and I was still unable to install. Links are provided below. I would greatly appreciate your help, thanks!

Bitconnect Wallet (Bitconnect-Ubuntu14-64bit.tar): https://github.com/bitconnectcoin/bitconnectcoin/tree/master/setup/bitconnect-linux-wallet

YouTube video (Ultimate Guide : INSTALLING A PGM FROM .TAR FILES !!!): https://www.youtube.com/watch?v=W9JcK70kThI

Step by step:

1.Download your software to /tmp/Bitconnect-Ubuntu14-64bit.tar

wget https://github.com/bitconnectcoin/bitconnectcoin/blob/master/setup/bitconnect-linux-wallet/Bitconnect-Ubuntu14-64bit.tar?raw=true -O /tmp/Bitconnect-Ubuntu14-64bit.tar

2.Open terminal with CtrlAltT and enter commands

cd /tmp 
tar -xvf Bitconnect-Ubuntu14-64bit.tar

sudo ./install.sh
sudo apt-get install libqt5widgets5

here:

• cd /tmp changes directory to /tmp;


• tar -xvf extracts Bitconnect-Ubuntu14-64bit.tar file (-x - eXtract, -v - verbose, -f - filename);


• sudo ./install.sh launches installation script to install program system-wide;



• sudo apt-get install libqt5widgets5 installs necessary Qt5 system dependencies.

3.You can find installed application in Applications menu or launch it from terminal with bitconnect-qt.
