Brother Printer - No module named 'pysnmp.hlapi.varbinds'

The problem

After upgrading from 2024.8.3 to 2024.9.0, the Brother Printer integration is failing.

Here is the complete traceback:

I'm not able to reproduce this. Do you use any custom integration using the SNMP? Could you check the version of the pysnmp package? (pip show pysnmp when HA venv is active)

[psfales]

(homeassistant3.12) $ pip show pysnmp
Name: pysnmp
Version: 6.2.5
Summary: A Python library for SNMP
Home-page: https://github.com/lextudio/pysnmp
Author: Ilya Etingof
Author-email: [email protected]
License: BSD-2-Clause
Location: /srv/homeassistant3.12/lib/python3.12/site-packages
Requires: pyasn1, pysmi, pysnmpcrypto
Required-by: brother

[psfales]

I experimented with different versions of pysnmp, both earlier and later than 6.2.5, but it didn't seem to make any difference. What version should I be using?

[jasonshugart]

I am getting the same error. I just upgraded from 2024.6. I have the same pysnmp version.

[psfales]

Ah, I got it working by going all the way back to pysnmp 6.1.3. I don't know when/how the newer version got installed or if it's going to cause other problems with HA, but it seems to be working OK right now!

[psfales]

For the record, my workaround for now:

pip install --upgrade pysnmp==6.1.3

As I say, I don't know what the downsides might be with doing that, but everything seeems to be OK for now.

[bieniu]

What version should I be using?

6.2.5 is the correct version but I checked and there is not even a pysnmp/hlapi/asyncio/sync/init.py file in version 6.2.5 so your package looks strange.

Please reinstall the package:

pip uninstall pysnmp pyasn1 pysmi pysnmpcrypto pysnmp-lextudio pysmi-lextudio
pip install pysnmp==6.2.5

[jasonshugart]

That worked for me. I guess some old junk was left hanging around.

[psfales]

Worked for me too. Not sure how it got into that state, but thanks for the help!

[bieniu]

HA 2024.9 migrates pysnm-lextudio package to original pysnmp (pysnmp has not been developed for some time because its creator died). As you can see for core installation migration did not proceed correctly.

[psfales]

Thanks for the insight. As a side note, I was confused about when the problem occurred because reverting to 2024.8.3 did not fix it. I didn't think I had seen it prior to 2024.9.0, but I was starting to wonder. It looks like whatever the migration did in 9.0 to break things persisted after reverting back to 8.3!

Hi, I have same problem. I run home assistant core on an LXC container in Proxmox. If I try this code:

pip uninstall pysnmp pyasn1 pysmi pysnmpcrypto pysnmp-lextudio pysmi-lextudio
pip install pysnmp==6.2.5

from LXC console I obtain: -bash: pip: command not found

Please help me!

6.2.5 is the correct version but I checked and there is not even a pysnmp/hlapi/asyncio/sync/init.py file in version 6.2.5 so your package looks strange.

Please reinstall the package:

pip uninstall pysnmp pyasn1 pysmi pysnmpcrypto pysnmp-lextudio pysmi-lextudio
pip install pysnmp==6.2.5

After doing this I get the error:

Logger: homeassistant.config_entries
Source: config_entries.py:2894
First occurred: 15:26:48 (1 occurrences)
Last logged: 15:26:48

Error occurred loading flow for integration brother: No module named 'pyasn1.compat.octets'

[sshaikh]

Okay looks like we need pysnmp 6.2.6 that fixes a recent change in pyasn1. How do we force this version? Each time HA starts it downgrades it.

[bieniu]

After doing this I get the error:

You need:

pip install --upgrade pyasn1==0.6.0

Look here https://github.com/home-assistant/core/pull/125712

[Tux92]

Hi, I have same problem. I run home assistant core on an LXC container in Proxmox. If I try this code:

pip uninstall pysnmp pyasn1 pysmi pysnmpcrypto pysnmp-lextudio pysmi-lextudio

Please help me!

Anyone can help me please.

[bieniu]

Anyone can help me please.

I guess you have to activate the python virtual environment first source <VENV_FOLDER>/bin/activate. You just need to know where the venv folder is in the container.

[Tux92]

Ok, but is this the only way to restore function of brother plugin or in next home assistant update all goes well?

Upgrading to 2024.10.0 started showing this for me too...

worked for me.

[reedy]

Yeah, but users shouldn't be needing to run commands manually ;)

It looks like https://github.com/home-assistant/core/pull/126488 is supposed to be in 2024.10.0, but hasn't fixed it?

[bieniu]

#126488 was not intended to fix this problem. I have tried to reproduce the problem on HA OS and HA Core multiple times and have failed, so I suspect some custom integration or sharing of venv with another python app/script is to blame. For some reason the pysnmp package is not being updated properly or is being overwritten.

Please check if any custom integration uses pysnmp package (this information is in the manifast.json file in the integration folder). If so, disable this integration and restart HA.

[swamplynx]

doing this:

pip uninstall pysnmp pyasn1 pysmi pysnmpcrypto pysnmp-lextudio pysmi-lextudio
pip install pysnmp

worked for me.

Can you just run this straight from the HA CLI (e.g. via the SSH & Web Terminal Add-On) or do you need to hop into a python venv first? I'm running HA OS. I ran it from the CLI which is already in the HA container. No dice. Is there a python venv I need to drop into?

In my case, i did have an old integration that was using pysnmp-lextudio. I proceeded to update that integration to pysnmp since it was custom, but that wasn't enough, i still needed to run the commands manually to purge the old packages before things would work properly.

I've just checked and only integration which using pysnmp according to manifest.json is brother integration - nothing else. And problem still exists :(

The release for https://github.com/jaroschek/home-assistant-eaton-ups/issues/32 seems to have fixed both instances that were showing for me

There hasn't been any activity on this issue recently. Due to the high number of incoming GitHub notifications, we have to clean some of the old issues, as many of them have already been resolved with the latest updates. Please make sure to update to the latest Home Assistant version and check if that solves the issue. Let us know if that works for you by adding a comment 👍 This issue has now been marked as stale and will be closed if no further activity occurs. Thank you for your contributions.

[sshaikh]

Fwiw I ended up disabling the integration (2024.9.1)

[przemoc86]

For me still not working - @bieniu maybe it's caused as I was testing Your version few months ago that You've provided on FB forum?
