What is the DNS of your Proxmox Host? Try to add 8.8.8.8

@MickLesk I have added 8.8.8.8 to my dns settings but the exact same error still occurs.
After the error it says fallback to 1.1.1.1 8.8.8.8 dns and i say yes but then it reverts to "user ended script" and does not work.

✖️ User exited script

Kind regards

On the Host?

Which country? DNS Blocks? Send Screenshots of your network config (Host) and DNS Settings (Host)

Try to Change your DNS 2 to DNS 1 and DNS 1 to 3

So:
DNS 1: 8.8.8.8
DNS2: 1.1.1.1
DNS 3: your special

If this works, your DNS doesnt respond at new Created LXC

I mean, its not up to us to solve this... Its not a script issue. Its your host/network thats having something wrongly configured.

What Happens If you remove all DNS expect DNS 1 with 8.8.8.8 and do an apt update && apt upgrade at Host?
