This guide assumes you’ve followed my other guide, where you compile Bitcoin Core from source. These steps will allow you to upgrade a running Bitcoin Core node to the latest version.

Stop current Bitcoin Core node

First, stop the running version of the Bitcoin Core daemon.

$ su - bitcoin
$ bitcoin-cli stop
Bitcoin server stopping

Check to make sure your node is stopped.

$ bitcoin-cli status
error: Could not connect to the server

Once that’s done, download & compile the new version.

Install the latest version of Bitcoin Core

To do so, you can follow all other steps to self-compile Bitcoin Core.

In those steps, there’s a part where you do a git checkout to a specific version. Change that to refer to the latest release. In this example, we’ll upgrade to 0.18.0.

$ git clone
$ cd bitcoin
$ git checkout v0.18.0

And compile Bitcoin Core using the same steps as before.

$ ./
$ ./configure
$ make -j $(nproc)

Once done, you have the latest version of Bitcoin Core.

Start the Bitcoin Core daemon

Start it again as normal;

$ bitcoind --version
Bitcoin Core Daemon version v0.18.0
$ bitcoind -daemon
Bitcoin server starting

Check the logs to make sure everything is OK.

$ tail -f ~/.bitcoin/debug.log
Bitcoin Core version v0.18.0 (release build)
