I tried many solutions listed in the forum, but none of them worked.
The commands I tried were:

They run without showing any error, but the segmentation fault is still there.

When an ordinary application (like apt) start segfaulting, and it seems like nothing has changed that might otherwise account for the problem, then try reinstalling the package.
sudo apt install --reinstall the_package_name
In this case, since apt is the problem, you can't do that. Instead, use dpkg to reinstall apt.
This is usually pretty easy:
- The original .deb package is sitting in your /var/cache/apt/archives
dpkgwill automatically overwrite the older package files with newer when simply told to --install (so you DON'T need to specify --reinstall to dpkg).
So poke around in your filesystem to find the .deb file and you get...
sudo dpkg --install /var/cache/apt/archives/exact_name_of_the_deb_file.deb
However, in this case, there's an additional problem: Sometimes folks delete the deb file from their /var/cache! They usually don't mean to - they just don't quite understand how apt works, and perhaps don't quite understand the magic shell incantations that they are inputting.
(Advice: DON'T input magic shell incantations. Take the time to understand what a command does before you run it. It might make things worse.)
You can overcome this problem by downloading the package using a web browser from http://packages.ubuntu.com. DON'T cleverly download the newest package from the newest release (that causes new problems). Just download the appropriate package for your release of Ubuntu.
Save the .deb package where you can find it. Then:
sudo dpkg --install /full/path/to/the/package.deb
If this didn't solve the segfault problem, then you have some other problem (like a wrong-release package) that simple reinstallation won't solve.
