Why are so many Linux shell commands unsupported in Proxmox?

[Ryan_Malone]

I'm trying to figure out what is using ports 80 and 443 in Proxmox and I tried to install netstat and it doesn't work. I tried basic commands like sudo apt update and the command isn't found. So 2 questions a) why is Proxmox so restrictive and b) what is actually available in Proxmox because everything works fine on all the VM's Proxmox is hosting? I stupidly assumed Ubuntu commands and tools would be available since the kernel is Ubuntu.

root@home:~# sudo ufw status
-bash: sudo: command not found
root@home:~# sudo apt install grep
-bash: sudo: command not found
root@home:~# sudo apt update
-bash: sudo: command not found

Hey, first things first, you don't need sudo as root user. Also, the errors you are getting are the same, telling you that you don't have sudo installed. You can manually download it with apt install sudo, but as I said, you don't need sudo if root is your only user. Could you try these commands without sudo and report back please?

Edit: Typo and clarification

A) You're already root, you don't need sudo unless you're in a non-root account

B) Are you sure ' sudo ' is installed? ' dpkg -l |grep sudo '

I'm a new Linux user and I got so used to using Sudo on the guest OS' I completely forgot I didn't need it as root.

Many people already replied correctly. To add a bit more color to this:

In Linux the very first thing you type is the command. Everything else is an argument/option to that command.
So, as was pointed out, you were simply running the same command over and over - "sudo". But you were supplying different arguments to that command.

By default "sudo" is not installed in PVE. The reason is that PVE primary management user is "root". And you should treat PVE as an appliance rather than a generic Linux box.

Good luck

1. Proxmox is an absolute well & robustly built TOTAL Linux HV OS - with all the necessary & commonly required packages - you usually need.
2. Sudo is not installed - you're anyway root.
3. The range of commands you have entered shows you no little to nothing about PVE or Linux.

The way you are going about it - YOU ARE GOING TO BREAK YOUR SYSTEM! - I'm sure.

I suggest, you first read up what there is (there is a lot out there) - get used to the PVE environment GUI first ONLY.

There is a learning curve - just go with it.

To get rid of the "Unauthorized IP" errors, disable the Enterprise repo in Nodes / [nodename] / Repositories (or buy a subscription)
Then Add the pve-no-subscription (and Test repo as well, if you're OK with it and have backups)

Then Reload and go to Updates / Refresh

I'm only on chapter 1 of 'The Linux Command Line'.

Well, it showed me what I was looking for so not sure what you mean. Breaking it instead of my production systems is exactly why I'm using this for my homelab.

Tried that. Assume I need a reboot.

In the GUI click on the node, go to Updates and then Repositories.
Select the enterprise entries and press the "Disable" button for each one.

You have already added the no-subscription repos, so there you don't need to do anything.

It seems you have enabled the pvetest repository. You should disable this one, too.
