Installation instrucion the for bitcoin core (tar.gz file from bitcoin.org in Linux/Ubuntu Desktop 18.04.)
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;
