osm2pgsql-replication: command not found on Ubuntu 20.04

[leongal]

Hi Guys
I installed osm2pgsql on my Ubuntu 20.04.
And when I try to use osm2pgsql-replication, it says osm2pgsql-replication: command not found.
I can see my osm2pgsql version is 1.4.1 and osm2pgsql-replication is available at >=1.4.2.
How can I upgrade my osm2pgsql version?
Also if I am going to use https://raw.githubusercontent.com/openstreetmap/osm2pgsql/master/scripts/osm2pgsql-replication this script for osm2pgsql-replication, where should I copy it to use as a command?
Thanks in advance!

Not really a bug, but https://switch2osm.org/serving-tiles/updating-as-people-edit-osm2pgsql-replication/ , which links to https://osm2pgsql.org/doc/install.html and https://osm2pgsql.org/doc/manual.html#updating-an-existing-database , might help you. See also https://switch2osm.org/serving-tiles/updating-as-people-edit-pyosmium/ which is a slightly more flexible alternative.

As you can see on Image, I did sudo apt-get install osm2pgsql and it installed osm2pgsql of version 1.4.1.
Do you have any opinion about this?
To update from osm2pgsql 1.4.1 to osm2pgsql 1.4.2, how can I do?

You've installed the version that is packaged with your operating system. If you want to run a later version, you can either upgrade from 20.04 to 22.04 (here and here suggest August 4th) or use the link I provided earlier.
