great news. Whenever you an, please post the steps 
Related question: with this upgrade, if you have the light turned on and you switch it off with the wall switch, does it turn off in Home Assistant?
cool excellent, Daigo if you could post the instructions (in a idiot guide for me ) that would be great, as I followed the posted instructions and still didnt work.
having the same issues here i am on hassbian stretch just updated to 0.55 the post https://github.com/home-assistant/home-assistant/issues/9752#issuecomment-334993733 seems to be a mix of different installs
yep. It seems on hassbian stretch they already merged the script that fixes it.
im all new to linux and stuff… how do you install that script…
it is installed via
sudo hassbian-config install tradfri
i have just done this and get the below error, is anyone able to help me out. I am on a fresh install of hassbian 0.55

I have also sudo hassbian-config upgrade hassbian-script to update the scripts …

Hi could you please share your steps ? Thanks
Here also. Hassbian 1.3 on Stretch. I tried some of the above scripts. None of them worked. Then afterwards I updated the Hassbian scripts and installed the Tradfri script. The following errors still occurring.

Same error here !
I did like @morberg said in his post. So basically you need to install tinydtls and aiocoap. In order to do so you first need to install cython. So stop HA, activative your virtual environment (if you’ve installed HA in one) and execute the following command:
pip3 install cython
This may take a while - even though it looks nothing happens, just wait for it to finish.
Afterwards enter the following commands (taken from here: https://github.com/ggravlingen/pytradfri/blob/4d4a682f2f646d41d2a6e4a65858e376f56e24ed/script/install-aiocoap.sh)
git clone --depth 1 https://git.fslab.de/jkonra2m/tinydtls.git
cd tinydtls
autoreconf
./configure --with-ecc --without-debug
cd cython
python3 setup.py install
cd ../..
git clone https://github.com/chrysn/aiocoap
cd aiocoap
git reset --hard 3286f48f0b949901c8b5c04c0719dc54ab63d431
python3 -m pip install --upgrade pip setuptools
python3 -m pip install .
Afterwards I restarted HA and TRADFRI was back. I hope these steps will help you!

Ah, sorry, forgot to mention that!
I’m on Stretch after updating yesterday (instruction from here). So my version of python is 3.5.3.
@Dean_James Seems like you are in a directory you don’t have access to?
If I try this, might this mess up later Home Assistant updates when it is actually fixed in a newer release?
Or is it safe enough to run this manual commands and installations?
Sorry, maybe I’m the wrong person to be asked about this. I can’t imagine this would cause any harm, because you’re just installing some packages, but on the other hand maybe I’m wrong about this…
This worked for me, thanks a lot
with the latest hassbian image?
