How to Install This Atom-Community on Linux Mint (based on Ubuntu 20.04)? #484

Glad to see the project continuing post the sunset of original atom from github. I guess my question is quite common, yet could not find the answer.

I have the atom github set up already on my machine (Ubuntu 20.04) with many packages (for python/C++ development and linting). So what would be the easiest transition into this atom community edition, and will all the packages (along with the atom synchronisation package which works with a github gist) just work out of the box?

Can I update something inside the app to get regular updates from this build? Or do I have to purge the existing version, then install atom-community from scratch?
Here are the details of my present installation.

• Atom : 1.60.0
• Electron: 9.4.4
• Chrome : 83.0.4103.122
• Node : 12.14.1
