ModuleNotFoundError: No module named 'osmium.replication'

[Ash-47]

I've been wanting to update my local nominatim DB (for entire planet) and I've been following the steps mentioned in this article.
https://www.linuxbabe.com/ubuntu/osm-nominatim-geocoding-server-ubuntu-20-04
Basically I've been following step #6 & onwards
In step #6 after installing the osmium python module, and making changes to the local.php to point to the pyosmium-get-changes script, when I install the command $/data1/nominatim/build/utils/update.php --init-updates, I get the ModuleNotFoundError for osmium.replication.

Ubuntu version I'm on 20.04
osmium installed verison 3.6.0
I installed osmium via pip
I sudo switch user as postgres as it has access to the nominatim database & then run this:
$/srv/nominatim/build/utils/update.php --init-updates

The complete error I get:

content of my /nominatim/build/settings/local.php:

PS: In the script above the replication url is that of great-britain, but I eventually want it to be pointing to the the entire planet diffs, I suppose using https://planet.openstreetmap.org/replication/daily should suffice (Please advice if this is fine)

Thank you!

Have you installed pyosmium as the user postgres? pip install will usually make the packages only available to the user that calls the command. So in theory you'd need to run sudo -u postgres pip install osmium but don't do that. postgres is a system user, you shouldn't run Nominatim stuff under that user. Create a separate one as described in the deployment docs.

Hey, I reinstalled osmium as postgres user as you had mentioned here, and post that the update command did work. I just wanted to know whether using https://planet.openstreetmap.org/replication/daily to run daily updates will be better or should I look for another source of data, but anyway, thank you for your inputs.

So you completely ignored the part where I said don't do that.
