Installation instrucion the for bitcoin core (tar.gz file from bitcoin.org in Linux/Ubuntu Desktop 18.04.) 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 &amp; quick installation of the tar.gz file which is downloaded from Bitcoin.org?
Not gonna write a 'tutorial', but here's a couple things that should be mentioned:

As you imply, ubuntu provides a standard 'snap' for bitcoin. easily installed via apt. Agree they are a PITA to use, so ...

if you use the tar.gz, just extract it somewhere, then (using the appropriate version number):


2a) check the signature on the hash file:
gpg --verify SHA256SUMS.asc
2b) and confirm the hash for the downloaded file matches the appropriate hash in the hash file:
sha256sum bitcoin-0.17.1-x86_64-linux-gnu.tar.gz
2c) Then the trick is to use this to get the files where they need to go (links included):
sudo cp -vR bitcoin-0.17.1/* /usr/
2d) Not sure what the 'right' way to start it is, but this works for me. I put it in the automatic startups:
bitcoin-qt&amp;
