Upgrade apt bitcoin-core package I originally set up my bitcoin-core node on Ubuntu 16.04 Xenial using apt.
The ppa:/bitcoin/bitcoin package repository that I used isn't maintained beyond version 0.15.0, so I need a different way to upgrade to the latest version.
Options seem to be to use either snap or compile from source.
Would appreciate any advise on options. I have full blockchain and I don't want to do anything stupid like deleting it.
Right now, everything is in /root/.bitcoin. Ideally, I'd prefer to switch to source compiling, so as not to run into this issue again.
If you have to update your Bitcoin core wallet you can just download the new version and open the new bitcoin-qt file.
