i got the same problems when i try to use the 1.5.0 to isntall it,systemd-resolved stopped me

[Dengor1984]

i have the same error on Debian 11.7 and 12:

dpkg: dependency problems prevent configuration of homeassistant-supervised:
homeassistant-supervised depends on systemd-resolved; however:
Package systemd-resolved is not installed.

[Skrufen]

Getting the same error, unable to get Home Assistant back up and running after a failed upgrade attempt.
Doesn't look like systemd-resolved is available on Debian 12?

apt-get install systemd-resolved

[st00m]

The dependency in supervised-installer is wrong.
systemd-resolved is part of package: systemd
At least in my Package: systemd Version: 247.3-7+deb11u2
See: dpkg -L systemd | grep systemd-resolve

I have the same issue. I tried to install homeassistant-supervised on Debian 11 with apt install ./homeassistant-supervised.deb and this are my logs:

[oleksandr-belei]

You can bypass this error by using the command sudo dpkg -i --ignore-depends=systemd-resolved homeassistant-supervised.deb

Or you can create a fake systemd-resolved package using equivs which will satisfy the missing dependency.

• Install equivs
  sudo apt install equivs
• Generate a template control file
  equivs-control systemd-resolved.control
• Fix the package name
  sed -i 's/<package name; defaults to equivs-dummy>/systemd-resolved/g' systemd-resolved.control
• Build the package
  equivs-build systemd-resolved.control
• Install it
  sudo dpkg -i systemd-resolved_1.0_all.deb

That should satisfy the homeassistant-supervised package’s dependency.

[rb090]

Thanks a lot @oleksandr-beley 🤝. dpkg -i --ignore-depends=systemd-resolved homeassistant-supervised.deb worked for me, I was able to install homeassistant-supervised on Debian 11 👍. But this is just workaround until the dependency in supervised-installer will be fixed, correct?

[oleksandr-belei]

Yes, this is just a temporary workaround. I recommend using the second method because using "--ignore-depends" may generate warnings about missing dependencies on the system.

[ikifar2012]

The dependency in supervised-installer is wrong. systemd-resolved is part of package: systemd At least in my Package: systemd Version: 247.3-7+deb11u2 See: dpkg -L systemd | grep systemd-resolve

It appears that has changed with Debian 12, I had to install it as a separate dependency on my system. That being said my focus right now is on supporting Debian 12 as the ADR states "When a new major version of Debian is released, the previous major version is dropped, with a deprecation time of 4 months."

I could not find easy way to change the dependency's on a per OS basis without generating multiple packages and considering there is only 4 months until deprecation, I think it makes sense to just stick with the workaround for now as any new installs really should be done on Debian 12 at this point. That being said I am always open to suggestions as long as they comply with the ADR

To add on this, here is a part of Bookworm's changelog:

systemd-resolved has been split into a separate package.
This new systemd-resolved package will not be installed automatically

I was able to simply do apt install systemd-resolved and everything worked again.

[tripunto]

Doesn't seem like systemd-resolved is available in Debian 12?

It seems that version 1.5.0 is only compatible with debian 12, where "YES" you can install systemd-resolved
I tried to install it several times on my raspberry and it didn't work and the one I had only works on localhost... it's impossible to access from another device on my network

I have debian 12 installed on another sd and yes I can install systemd-resolved, but before installing it I want to make a backup... I already downloaded kde plasma 4 times

EDIT: I will have to install version 1.4.3

As soon as I install the systemd-resolves, the DNS stops working and does not resolve any host
​
ping: checkonline.home-assistant.io: Temporary failure in name resolution [info] Waiting for checkonline.home-assistant.io - network interface might be down... ^Xping: checkonline.home-assistant.io: Temporary failure in name resolution [info] Waiting for checkonline.home-assistant.io - network interface might be down... ^Cdpkg: error processing package homeassistant-supervised (--install): thread installed package homeassistant-supervised script post-installation was interrupted Errors encountered while processing: homeassistant-supervised

EDIT2: after uninstalling systemd-resolved from debian 12, the DNS works again, but it is required and without it it cannot be installed...
so 1.5.0 doesn't work at all

[Skynetnexus]

Following the Home Assistant Supervised installation page, I kicked off a new Debian 12 installation last night and the internet worked until I started installing the dependencies ( one by one ) , as soon as I installed systemd-resolved the DNS broke. The only way I could continue the installation was by running "sudo systemctl stop systemd-resolved".

For me the issue is systemd-resolved is not playing nicely the Debian 12 or one of the other dependencies ( listed below ).

apt install
apparmor
jq
wget
curl
udisks2
libglib2.0-bin
network-manager
dbus
lsb-release
systemd-journal-remote
systemd-resolved -y

[snakuzzo]

If it can help someone...
As @Skynetnexus said, when you install systemd-resolved, it doesn't work fine using stub listener (default option). If you disable stub listener, using another DNS server, it works fine.

So...to bypass the issue...

sudo apt install systemd-resolved

At this time, this breaks name resolution...

sudo nano /etc/systemd/resolved.conf

Uncomment this lines with no stub listener and your DNS server (eg. your router address):

DNS=192.168.1.1
DNSStubListener=no

Save and restart systemd-resolved

sudo systemctl restart systemd-resolved

Now check name resolution and go on with installation

[Skynetnexus]

@snakuzzo Thank you so much! Your solution has enabled me to complete the installation of home assistant and I now have a working installation after trying many other solutions.

Unfortunately my internet died again before I could apply my save Home Assistant backup. I am not sure if this was the root cause but I have previously been advised to disable ipv6 inside home assistant ( settings/system/network ) which I did and then to entered the commands below to get the internet going again. The internet is now working, even after multiple reboots.

sudo systemctl stop systemd-resolved
sudo systemctl disable systemd-resolved
sudo systemctl enable systemd-resolved.service
sudo systemctl start systemd-resolved.service

Is there a planned fix for this? ... Khadas VIM4 only have a Debian11 avaliable at this point in time.

Thanks, I did follow the guide :D .. it fails on the first step. systemd-resolved fails completely ... its trying to install version 252 but the system is actually 247

[snakuzzo]

If you follow guidelines, You have to use last Debian stable release (12)

Impossible :D as many SBC boards dont have Debian12 .. only Debian11.

[snakuzzo]

Try this
Anyway, Debian 11 is officially supported just for 4 months from the latest Deban 12 stable release.

This failed... there was a 'Too many errors, failing' and then aptitude quits

I rolled back the supervised installer to 1.4.3 and continued.

I'm hella confused. I'm on Debian 11. And it shows no install candidate for systemd. Should I update to Debian 12 and run HA installer to fix this issue?

[snakuzzo]

HA Supervised is officially supported on latest stable release (Debian 12). So...you need to upgrade to Debian 12 (search on googole, there are a lot of guides) and follow official guidelines to install/upgrade HA Supervised installation. When you will installa systemd-resolved and you will got DNS resolution problem, all you have to do is follow these steps

[andygikling]

@snakuzzo

Your solution does work around the issue. However, it has shortcomings:

• It does not work for anyone using a subnet other than 192.168.1.1/24 - there might not be a DNS server at 192.168.1.1 for many people.
• One could also set FallbackDNS=8.8.8.8 in /etc/systemd/resolved.conf and then you'd get Google's DNS which should always work but might be slower for some people.
• According to this, supervised-installer should not be dependent on systemd-resolved in Debian 12 (as suggested previously in this thread) https://www.debian.org/releases/bookworm/amd64/release-notes/ch-information.en.html#systemd-resolved

A real fix is needed here. In Debian 12, DNS works correctly out of the box. Installing systemd-resolved is what's breaking things. We have two good options to move forward with:

• Make systemd-resolved install correctly on Debian 12.
• When Debian 11 falls out of support here soon, change supervised-installer to not require the systemd-resolved package (hopefully HA Core and other supervised components do not actually require systemd-resolved specifically).

[snakuzzo]

I agree...

But about 192.168.1.1, that was just an example ;)

[ffries]

I installed Debian 12.1 on a PC Engines APU2 board and I was stopped by this issue until I added DNS server to /etc/systemd/resolved.conf. This is quite a simple bug but it will stop all users if not documented in the main documentation.

[snakuzzo]

This Is wrong. resolv.conf should not be manually eidted. Read this and this

[imkermichel]

USE DEBIAN 12, 11 WILL NOT WORK
edit /etc/resolve.conf
set nameserver to 8.8.8.8
save file
systemd-resolved will pickup the change and dns will work again.
login to webinterface and create your account.
when finished reboot you system

[snakuzzo]

As I said before...edit resolv.conf is not a best practice
