snmp in 2024

[morphxyz]

Hi all.
I tried different instructions to get snmp to work ranging from 2012 to 2023:

https://wansec.ch/2023/12/03/configuring-snmp-on-proxmox/
https://svennd.be/how-to-install-snmp-service-on-proxmox/
https://github.com/in-famous-raccoon/proxmox-snmp
https://wiki.esia-sa.com/snmp/snmp_proxmox
https://gist.github.com/hunzo/5431f997ae4136196183a5d08db28952

I just can't get PRTG to display anything. did something change with snmp?
It's a fresh Proxmox 8.1.4 installation.
the local network is open.

I have then tried to install snmp-mibs-downloader but I fail to do so aswell. No matter what repository I add I get:

E: Package 'snmp-mibs-downloader' has no installation candidate

Is it really that hard getting snmp to work?

Kind regards.

I don't know about hard, but adding the non-free repo and installing the desired packages does not seems so hard to me.
