Hello, I’m very new to proxmox and networking but enjoy learning about them. I tried last night to install proxmox v9 on a new mini pc. Booted off USB drive and installed following YouTube tutorial. Immediately ran into several issues. I will explain what I did and have done to try and resolve said issues.
Started by setting IP and DNS to the same as the YouTube video. That was mistake #1. After being unable to boot properly I figured out I needed a proper IP not in the DHCP range of my router and to match the gateway and DNS of my router.
So I reinstalled proxmox using IP 192.168.8.10 and matching DNS and Gateway to my router. My router is a Flint2 GLI MT-6000 and I know the router IP is 8.1. DHCP range is 8.100-8.249 according to google. I couldn’t find it in the actual router menu. After this, I could log into the KVM and I think I was able to SSH in using CMD on my other windows pc. I couldn’t run the post pve helper-script because it wouldn’t name resolve the GitHub site. So I thought maybe it was because my router has AdGuard Home enabled.
So I reinstalled proxmox again using IP 192.168.8.10 and then I changed DNS to 8.8.8.8 and matched the router gateway again. Then when I tried to ssh, I got a big warning about a host key having changed and possible malicious intent. I tried multiple code suggestion on the forum like deleting old keys, regenerating new keys etc but nothing worked to get rid of the warning and I couldn’t ssh in.
So once again I reinstalled proxmox using IP 192.168.8.11 to get a fresh key with no conflicting IP’s. DNS set to 8.8.8.8 and Adgaurd home disabled on the router. Matched gateway to the router. I was able to successfully ssh in and also log in to the KVM shell but when I tried to run the post-install helper-script I still got the error that it couldn’t name resolve the GitHub page. I was able to ping 8.8.8.8 and it never stopped receiving data from it. Could not ping google.com.
I tried running apt update but every update failed. Can’t remember what it said as I’m typing this on my phone at lunch break.
I tried numerous suggestion I found on numerous forums here such as /etc/resolv.config and many others like it. Each time I get a permission denied response even though I am the root user
It’s probably a simple solution but I couldn’t figure it out last night
Additional details:
This is my first and only proxmox install so there is only a single node
Installed on a brand new mini pc with 1TB NVMe, wifi and lan compatible. Have the lan cable hooked up to the mini pc and using wifi on my windows pc to ssh and use the web GUI
My goal is to first get pro mix functioning and then to run Jellyfin lxc,
Hal’s on VM. And then build on from there. Maybe add immich at some point.
If anyone can help me out with this, I would greatly appreciate it
Thanks
