Now we are ready to start the installation (compilation) process.
This will take a while... if you are installing this on the VPS server, then you can go and grab coffee/beer/wine/water... as it will take a while.
cabal build all
as the last step in our installation process is to copy newly compiled bin (executive) files to an early created folder: .local/bin
if you had a previous version of Cardano node running, then before you copy the new binary files, make sure that you have stopped your current Cardano-node processes, otherwise, you will not be able to overwrite the new file.
