First steps with Charmed OSM

Hello,
I have been trying to follow this tutorial steps (OSM Development Stack). When I run: osmclient.overlay, I get this error: osmclient.overlay: command not found. So, I’ve decided to follow the official docs installation for OSM charmed (https://osm.etsi.org/docs/user-guide/03-installing-osm.html#charmed-installation). When I run: ./install_osm.sh --charmed, I get this error that I can’t solve:permanently dropping privs did not work: File exists

I can’t find anything that works and I am in a dead end.
Can you please help me?

Thank you for your time
