Whenever I try to install any software from ubuntu software centre, I receive a message saying "cannot do that"
click on the above link to see the image that I get
When I choose to download it from terminal it says:
E: Unable to parse package file /var/lib/apt/lists/ppa.launchpad.net_snwh_pulp_ubuntu_dists_xenial_InRelease (1)
E: The package lists or status file could not be parsed or opened.
What do I suppose to do and first of all please tell me why this error is occurring?

Run this command in terminal
sudo rm -r /var/lib/apt/lists/*
And Then
sudo apt update
I think your /var/lib/apt/lists/ files are corrupted So You Can delete them to regenerate them.
This error is usually caused by trying to install software that is packaged as a "classic snap" rather than a normal snap or a deb package. Classic snaps cannot be installed using the Ubuntu Software application due to the way they are packaged (why they even show up in Ubuntu Software is a mystery to me). You can install them using the snap command-line tool. First, search for the app (i.e. for slack):
snap search slack
The notes column will say classic for classic snaps. These are the kind that must be installed using the command line:
sudo snap install slack
this will warn you about the security risks of a classic snap and advise you to append --classic if you understand them:
sudo snap install slack --classic
