How to install the libwebkitgtk package on Ubuntu 20.04 LTS?

Question

So I am trying to install Solar2D (formerly known as Corona SDK) to make a mobile game. After installing the dependencies, when I run Solar 2D I get the following error:

/home/user/CoronaSimulator/CoronaSimulator: error while loading shared libraries: libwebkitgtk-3.0.so.0: cannot open shared object file: No such file or directory

I tried installing libwebkitgtk using sudo apt-get install libwebkitgtk-1.0-0 but I get the following message in Terminal:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package libwebkitgtk-1.0-0 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'libwebkitgtk-1.0-0' has no installation candidate

Answer 1

Following the steps here fixed the issue for me

Open terminal and write this:

1. sudo nano /etc/apt/sources.list
2. Add this entry to the file and save:

deb http://cz.archive.ubuntu.com/ubuntu bionic main universe

3. sudo apt-get update

4. sudo apt-get install libwebkitgtk-1.0-0 -> if you are using Vega and jdk of 64 bits

   sudo apt-get install libwebkitgtk-1.0-0:i386 -> if you are using Vega and jdk of 32 bits

This is not a full answer, but I solved my similar problem by discovering that a prior older dependency was needed to be installed first before libwebkitgtk-3 would successfully install. Specifically, I needed libjavascriptcoregtk to be installed on the system before I could successfully attempt to install libwebkitgtk. I'm not sure if libjavascriptcoregtk was needed by libwebkitgtk or by the program I'm using, but either way, it was apparently required first.

So there may be some other dependencies you need to have satisfied first before your install can proceed.

KNIME has a similar dependency. In Debian, the new needed libraries are:

libwebkit2gtk-4.0-37

libwebkit2gtk-4.0-37-gtk2

(Using the standard repositories)

sudo apt-get install libwebkit2gtk-4.0-37

sudo apt-get install libwebkit2gtk-4.0-37-gtk2
