Installing Home Assistant Supervised on a Raspberry Pi with Debian 11

I have gotten it to boot after reboot with the same adapter
You have to change the /boot/cmdline.txt part of root=LABEL=RASPIROOT
by root = PARTUUID = XXXXXXXX-02
which you get by typing when you first install “blkid”
To make the change, you can do it with the SSD disk placed in a PC

I have the same issue with a StarTech adapter. Any fix for this?

I just saw others are having issues with a resent debian update where after the update the pi 4 will not boot off the usb.

“So I run Debian on RPi 4 8GP from an m.2 connected to the usb 3 port of my Pi and ran an apt update upgrade today 4.4. that results in the dismount and failure to detect the usb device on boot. As I am not that familiar with linux I spent a few hours trying to figure out what the upgrade does, but to save others the trouble of figuring a quick and dirty workaround. The upgrade adds a new initrd.img-5.10.0-0.bpo4-arm64 in the firmware partition.”
This is what I was talking about when I questioned rpios vs Debian. I experienced this same issue trying to run supervisor on Debian. After the update it would not boot off of the usb.

hi… is there any fixed on Debian?

Not that I know of. Still holding back linux-image-arm64 here and all is good.

As I wrote before one has to wait for initramfs-tools version 0.140 to be released for buster (still version 0.133 as of now) before updating the kernel. It got already released for bullseye though.

Maybe we have to wait until it shows up here?

I tried this on a fresh install and you need to upgrade to install SUDO, Not sure how you do this with 2021-03-04-raspios-buster-arm64? apt install sudo -y doesn’t work.

Can’t run this command on a new install following the directions above. Need Sudo install first and this fails without the update. What needs to be done on a new install?

Where did you get 2021-03-04-raspios-buster-arm64 from? That seems to be the wrong image. For the Raspi 4 4GB you need the latest image from here which is:

The first thing you do after just having installed Debian is to go to the CLI and type:
apt install sudo -y

Only after that you initiate:
sudo apt-mark hold linux-image-arm64

After the two above steps you can run:
apt update && apt upgrade -y

Read the OP’s instructions carefully. This guide is not for RaspiOS but for HA Supervised on Debian 10 Buster.

I figured it out.

Looks like the install worked, the snapshot worked but I am having an issue trying to get Samba to work. Followed the linked samba directions and I get

 sudo service smbd restart

sudo: unable to resolve host rpi4-20210210: Name or service not known

Not sure where to fix this?

Hello, If I well understood, your instructions fix the issue of a RPi4 hanging after “random crng init done” message while booting from SSD (no microsd), for a new install.

But how to fix an already installed Rpi4/Debian/HA supervised on ssd and no more booting after Debian update without starting from scratch?


If you have already done the reboot after the kernel update to 5.5.10 and the RPI4 is stuck within the boot process now there is little that you can do left. Debian images are loading kernel and initramfs directly from RPI firmware without using a bootloader like i.e. Grub thus not providing any choice to boot from an older kernel.

I’m afraid you have to redo the whole OS installation from the start. Take care:
You must run

apt-mark hold linux-image-arm64

BEFORE running the first regular system update or else the installation is doomed again and the system will not start!

Nah that’s not needed @Tamsy

You can connect the USB drive to your computer and edit the boot.cfg file and change all 5.10 references to the 5.9 filenames (the 5.9 files should be in that directory as well)

Nice to know that :slightly_smiling_face:

But where to find the file boot.cfg? I know this file from VMWARE only. On other modern Linuxes you can set boot options through /boot/grub(2)/grub.cfg but Grub is not available for Debian on arm64.

Thanks. Really hoping to save my current installation. Where can I find that file?

Did you make a snapshot before the failed system uppgrade? If yes you should be able to connect the SSD to your PC, browse into /usr/share/hassio/backup and copy your snapshots to your PC for easy recovery after the base install of your rpi4.

The boot folder should be auto-mounted and visible (on a windows machine that is, otherwise /boot)
Just connect the USB drive to a computer and you will see

Or you can run from cli:

sudo ls -la /boot

which brings up (where kernel 5.5.10 is not installed:

drwxr-xr-x  3 root root     4096 Apr  2 12:12 .
drwxr-xr-x 18 root root     4096 Feb 14  2019 ..

-rw-r--r--  1 root root 22656880 Dec 31 15:19 vmlinuz-5.9.0-0.bpo.5-arm64

but unfortunately no boot.cfg

Running as root (su - for all permissions over the system):
locate boot.cfg

delivers an empty result.

Ok sorry so it’s not in the boot folder. Been a couple of weeks when it happened to me and had to apply this fix.

Anyway just connect the USB disk to a computer. On a Windows computer there will be only partition mounted and that is where all the files boot files are (you don’t even get to see the Linux drive what you are seeing now).

boot.cfg obviously only exists on machines running vmware.

Running as superuser

locate boot.cfg

delivers an empty result.

Which means there is no boot.cfg for Debian 10 on arm64 (as I pointed this out before).

Unfortunately no up-to-date snapshot just before the system upgrade.
I’m not so familiar with Linux/Debian, but can’t believe the recommended system upgrade can make my whole home automation unusable and there is no way to recover/rollback without full reinstall. :sob:
There is no way to change the firmware or overwrite the wrong files manually?
