Fresh install of ZimaOS. SSH commands missing?

Hi there,
I just installed Zima OS 1.5.4 on my Beelink Me Pro and it was immediately accessible remotely on my own network. Problem is, some SSH commands don’t seem to be working, what am I missing?
curl and jq seem to be working properly, but docker-compose and openssl are not recognized. How do I implement them?
Same question for standard packages (apt-get, opkg, apk). I expected them to be natively available through ssh but they don’t seem to be there. What am I missing?

I was planning to have them available to install a couple things (like Netbird) on premise.

Sorry for these questions, I am new to SSH but willing to learn!

Thanks in advance.

@domito In Zima OS, you cannot use package managers from other Linux distributions (such as apt-get, opkg, or apk). If you want to install Netbird, it is recommended to deploy it using Docker. If the docker-compose command is not available, you can try using docker compose instead.
