There are many discussions going on as there is a lack of a simple tutorial as to how to install Bitcoin Core (GUI) on Linux distributions, i.e Ubuntu 18.04.
Bitcoin.org offers the tar.gz file (i.e. available here: https://bitcoin.org/bin/bitcoin-core-0.20.0/bitcoin-0.20.0-x86_64-linux-gnu.tar.gz) which can be installed in Linux, i.e. Ubuntu Desktop 18.04 or 20.04.
It would be great if someone could provide such instruction to reach out to a broader user base. Not all users wish to use the Snapstore.
Is there anybody who could write up a tutorial or just post a video for a safe & quick installation of the tar.gz file which is downloaded from Bitcoin.org?
