I found pencil on Ubuntu software store, which was a buggy nightly build. So, I went ahead to its official site and downloaded its latest stable version using this link. It was in the form of '.Appimage' . So, I checked this:What is an "AppImage"? How do I install it? forum, and did accordingly. Terminal shows the following Screen:
milkybar@Milkybar-Computer:~/Downloads$ chmod a+x pencil2d-linux-i386-0.6.2.AppImage

So, I installed GCC-7 from here Now, terminal shows:

What do I do Now?
I am a Pencil2D developer and am actually the one responsible for managing the 32-bit Linux AppImage. This issue is a result of our AppImage being built with a newer version of glibc than the version you have. From the AppImage documentation:
We will look into the suggested fixes for future releases, but in the mean time there are multiple other ways you can use Pencil2D. I would recommend Pencil2D's Flatpak from Flathub. It's about as easy to install and use as the AppImage and is currently less buggy. Pencil2D can also be installed on Ubuntu through apt, however the last version available for xenial is obsolete and it is strongly recommended that you do not use it. Finally, for the ambitous, the application can be built from source. We provided a detailed guide on how to do this here: https://github.com/pencil2d/pencil/wiki/Building-Pencil2D-on-Linux.
