TRADRFI - Could not install all requirements

Configuration
1

Hey guys,
I am having some problems with the tradfri component.
My log shows me:

Could not install all requirements

Component Wiki told me:

The Python version 3.4.4 or greater is required for this component. The component will not initialize without this and will report a Could not install all requirements error in the logs.

My terminal tells me:

/homeassistant$ python3 -V
Python 3.5.2

However - i tried to set up the newest version, but I am getting some errors and don’t know from here:

sudo apt-get install python 3.6.3

E: Unable to correct problems, you have held broken packages.

Has anyone encountered similar problems or can tell me how I can fix this?
I am running my instance on Ubuntu 16.04.3, homeassistant in Python virtual environment.

Thank you!

I followed this guide to install python 3.6 on ubuntu 16.04.
After that, set up a new venv like stated here.
Tradfri needed manual install of cython in the venv.
pip3 install Cython

Thank you very much VDRainer and martijnm,

I tried both of your solutions - I managed to install python 3.6.3 but it could not solve my issue unfortunately - still same errors… :frowning:
I guess I have to get rid of those “broken packages” or fix them somehow.

E: Unable to correct problems, you have held broken packages.

My Google excourses give me possible solutions:

apt-mark showhold
sudo apt-mark unhold

but showhold gives me no output.

Second solution:
using aptitude

sudo aptitude install myNewPackage

also no help.
I have no clue.

I will try to setup a new VM an fresh install.
Maybe that helps…

I managed to fix my broken packages!
Thats good again for now!

But HA still cant install these dependencies…

Any Ideas here?

Unable to install package pytradfri[async]==4.1.0: Command “/home/smartassi/homeassistant/bin/python -u -c “import setuptools, tokenize;file=‘/tmp/pip-build-pkiij55e/DTLSSocket/setup.py’;f=getattr(tokenize, ‘open’, open)(file);code=f.read().replace(‘\r\n’, ‘\n’);f.close();exec(compile(code, file, ‘exec’))” install --record /tmp/pip-2n88wpfe-record/install-record.txt --single-version-externally-managed --compile --install-headers /home/smartassi/homeassistant/include/site/python3.6/DTLSSocket” failed with error code 1 in /tmp/pip-build-pkiij55e/DTLSSocket/

In case anyone encounters the same problem - I now managed to fix it!
There was a problem with the installed python version 3.6.3.
I had to recompile and install it.
For that I followed instructions from:

Thus running command:

apt-get install -y make build-essential libssl-dev zlib1g-dev libbz2-dev libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev xz-utils tk-dev

Thereafter I downloaded and untared python3.6.3 to my homefolder:

cd ~
wget https://www.python.org/ftp/python/3.6.3/Python-3.6.3.tar.xz
tar xf Python-3.6.3.tar.xz

Then compiled it with options:

./configure --enable-optimizations --enable-loadable-sqlite-extensions
make
sudo make install

Hope that this can help you!

Thanks for all other help I got.
Greetings Walter
