core: 'Setup failed for dhcp' in 2023.4 and 2023.4.1

The problem

I have 3 errors (included below) relating to this in the log and cannot use integrations relying on the import (ESPHome and Broadlink, in this case)

After updating to 2023.4, everything was initially fine. A few hours later I restarted Home Assistant, that was when I first saw this issue. I didn’t log anything as I didn’t have time to investigate until now.

I just updated to 2023.4.1 and the issue was fixed. Then I restarted again, and the issue is back.

What version of Home Assistant Core has the issue?

2023.4.1

What was the last working version of Home Assistant Core?

2023.3.6

What type of installation are you running?

Home Assistant Supervised

Upgrade dnspython to 2.3.0

Thank you, this seems to have resolved it for now.

For anyone else with the same issue:

user@host:~$ docker exec -it homeassistant bash
bash-5.1# pip3 install --upgrade dnspython==2.3.0

I believe I’ve tracked down the issue that was affecting me. It was a custom integration - minecraft server status (but not yours @jdeath, but thanks for the pointer). A long time ago I must have manually added the integration (there is now one in core) and it was using an old mcstatus dependency.

A useful debug tool to track down dependencies might be to install pipdeptree inside the homeassistant container:

# get inside the container
docker exec -it homeassistant bash
# install pipdeptree and run it
pip install pipdeptree
pipdeptree

That will output all packages and dependencies, and you can look for what is using dnspython3. In my case I saw:

mcstatus==5.1.1
├── asyncio-dgram [required: >=1.2.0, installed: 2.1.2]
├── click [required: >=7.1.1, installed: 8.1.6]
├── dnspython3 [required: >=1.15.0, installed: 1.15.0]
│   └── dnspython [required: ==1.15.0, installed: 2.3.0]
└── six [required: >=1.14.0, installed: 1.16.0]

It might then be useful to search for references to that package, something like:

find / -xdev -type f -print0 | xargs -0 grep -H "mcstatus"

But thanks to @jdeath I already suspected something minecrafty and found the old custom component (this wasn’t installed via HACS so I wasn’t spotting it previously and had to delete it manually).

@energywave The latest update I pushed a few days ago should fix the problem. It now uses the same mcstatus version as built-in integration. No reason to update past the one used by home assistant as that could cause other issues. The issue should be gone after upgrading and restarting homeassistant a couple times.

jdeath on Apr 17, 2023

This is still an issue for 2023.4.2 , although it did not show up again until a few restarts. Weird! Opps. I didn’t see this could be a custom component issue. Anyone with this issue happen to use my minecraft custom_component that adds bedrock support? After some digging, it has a pinned mcstatus, which requires dnspython3, which requires dnspython. I’ll try update that to be in line with current versions.

@JBP77 Install the “SSH & Web Terminal” addon. turn off protection mode, ssh in and type (it is in a few posts higher):

user@host:~$ docker exec -it homeassistant bash
bash-5.1# pip3 install --upgrade dnspython==2.3.0

Upgrade dnspython to 2.3.0
