Thx for the welcome! I feel like I’m over my head as I am just starting out. I’ve tried several things and it looks like my root problem is this message: The package os-agent needs to be reinstalled, but I can’t find an archive for it." I’ve done several searches and can’t find an answer to that one!
It’s part of the installation instructions

I am really frustrated! I have restarted, retried and keep running into different roadblocks. I now have a stable dual boot system with Windows 11 and the latest Debian install GUI. I opened the Terminal and started following these instructions carefully. (Of course, using Terminal in the GUI, the very first command line is just “su” to get to the root rather than the longer “sudo -i”.
This time when I got to:
curl -fsSL get.docker.com | sh
I get:
curl: (6) Could not resolve host: get.docker.com
I’ve seen this question before and the answers were above my head. Can someone give me simple step-by-step commands to run in the terminal to get through this step/command??
This guide covers installing HA Supervised on a Debian 12 based system, no GUI and no dual booting.
If you are installing in some way that is outside of the scope of the guide, please don’t ask for support as you have not followed the guide.

Where can I get help. Certainly I’m not the only one hot using a Rasberry Pi.
As for installing Home Assistant Supervised on a Raspberry Pi using Debian 12 there is even a dedicated guide for doing so.
Nevertheless same with this guide: No GUI and no dual booting!
Is there any special reason why you want to install HA Supervised? I recommend you to stay away from HA Supervised since this kind of installation makes solid Linux knowledge mandatory.
Home Assistant Operating System (HA OS) might be more suitable for you and you dont need much Linux knowledge to install and run Home Assistant:
For an in-depth reading about the latter look HERE.
BTW, the Search-function of this forum works pretty well

You have a dns issue.

It will not make a difference if the computer is dual booted.
I’d suggest trying to dual boot Windows 11 and desktop Debian on a Pi while using the x86/64 guide will almost certainly make a difference.
Are you saying this because of the desktop on debian?
Because of this and previous comments. Perhaps I’m misunderstanding.
You’re both right. Op should probably use the other guide. But nevertheless this is a DNS issue. Fix that or nothing works
I’ve seen this before, and it turned out to be a IP6 dns issue, so maybe try again using IP4 only?
Thx all. A couple things. I appreciate the comment about dual booting not affecting anything since when booted to Debian, it can’t see the other partitions. I want to use supervised for several reasons. I’m trying to relearn skills I forgot in the 80s so I greatly appreciate this community!!
So, overnight I DID wipe my entire hard drive yet again and then used the latest Debian installer, selecting the non GUI version. I partitioned the drives successfully and got through the debian issue by using this command: sudo apt install docker.io. That doesn’t need DNS since it was already in the repository.
But several of you are correct that is was a DNS issue. Now the key command to Home Assistant · GitHub … failed with a similar message about unable to resolve host. I have been trying to find a link for fixing DNS issues in plain language. LOL! I’ll keep searching, but if someone can help, I would apprciate it!
apt does use dns because it downloads from a repository.
Actually, i had the same (even in this post 
)
Anyway, i found supervised too strickt, i couldn’t run some other stuff i needed (as the supervisor would uninstall it again)
Still decided to stick to Debian (with gui) and use VMWare workstation (as i was on W10 before)
However I did move some add-on’s to docker on the host ( and who knows, maybe some day i might abandon supervised )
Find your active interface:
sudo nmcli con show --active
The output shows something similar to:
NAME UUID TYPE DEVICE
Supervisor eno1 e874k675-44d4-31a4-8cf8-3b8cc5f3b7cb ethernet eno1
lo 1e5bf4e3-e5c6-40d4-a193-0ffaa1l4fd2b loopback lo
where
e874k675-44d4-31a4-8cf8-3b8cc5f3b7cb
is the active interface of my RPI4 used by Supervisor.
Now run the following command but use the UUID of your active interface:
sudo nmcli con mod "e874k675-44d4-31a4-8cf8-3b8cc5f3b7cb" ipv4.dns "8.8.8.8, 8.8.4.4"
With the above command you configure the RPI to resolve TLD’s using Google’s DNS servers (8.8.8.8 and 8.8.4.4). Of course you can change this to whatever valid DNS-servers of your choice.
Restart the NetworkManager service:
sudo systemctl restart NetworkManager

Hi everyone!
A clean supervised installation of HA on a new installed Debian 12 (bookworm) with LXDE. No other applications were installed. The installation was done accordingly to this guide.
First of all, the host with HA in unreachable.
The second issue:
journalctl -f shows that installation is stucked at “Get “https://ghcr.io/v2/””
Here is the log:

Please give me any suggestions on this error.
Thank you in advance
DNS issues also?
Thank you for your comment.
It’s kinda network issue, I think
root@debian-ha:~# ha resolution info
Error response from daemon: No such container: hassio_cli
I think because the HA is not fully installed
