Python upgrade

Installation
81

I asked you in an earlier post to paste the contents of your service daemon. You should find it in /etc/systemd/system folder.

You need to locate your instance of Homeassistant and launch it manually.

Assuming you originally installed HA using these instructions https://www.home-assistant.io/docs/installation/raspberry-pi/

you should be able to launch HA manually.

Just to be clear. You did manually install HA on the Raspberry Pi and not install from a Hassbian image

82

Thank you very much for your help. You know, at the end I made a new installation of Hassbian (hassbian image) and after some hours of installation and configurationā€™s work, the Home Assistant works and has Python 3.7.3 installed on it! (Alleluya!). In truth, there is something that stopped working: the icons that I installed from ā€œmaterialdesignicons.comā€. Is there something Iā€™m missing to update?

83

Have you checked your logs.

84

I found an error in configuration.yaml. ā€œhomeassistantā€ appeared in 2 places. Now everything works perfectly. Thank you again!

85

Youā€™re welcome. Your logs are your best friend in HA.

Is anyone else having a problem with gstreamer after upgrading python? I did a pip3 install gi to get past the first issue of it not finding the gi module, but now I get:

I never said they shouldnā€™t. I was responding DIRECTLY to a comment you made regarding things NOT working in docker (they actually work, but you have to implement them differently).

Youā€™re arguing against my comments informing you of a DIFFERENT way to accomplish what you wanted. Itā€™s silly really.

88

Iā€™m stuck at step 17:

Error: Command ā€˜[ā€™/srv/homeassistant/bin/python3.7ā€™, ā€˜-Imā€™, ā€˜ensurepipā€™, ā€˜ā€“upgradeā€™, ā€˜ā€“default-pipā€™]ā€™ returned non-zero exit status 1.

89

Did you copy the line exactly as it was stated.

  1. /usr/local/bin/python3.7 -m venv .
90

You stated that they work, and I am sure they do in some way or another.

What was not explained is HOW do get them working in sufficient detail, under my new Docker configuration.

As I said, deprecating Python 3.5 left those who installed Home Assitant as a venv in the lurch. If this was done after Buster was released, then it would be an acceptable upgrade path. So far, Buster is not officially the ā€˜current stableā€™, and hence my comment on lack of choice, which others have voiced too.

91

Apparently that module is not yet compatible with Python 3.7. The print() command requires parentheses. I think they were optional previously.

92

I got this working. It looks like it installed gi 1.2 and it needs 1.0. How I fixed mine:

ln -s /usr/lib/python3/dist-packages/gi /srv/homeassistant/lib/python3.7/site-packages/gi
cd /srv/homeassistant/lib/python3.7/site-packages/gi
ln -s _gi.cpython-35m-arm-linux-gnueabihf.so _gi.cpython-37m-arm-linux-gnueabihf.so
cd overrides
ln -s _gi_gst.cpython-35m-arm-linux-gnueabihf.so _gi_gst.cpython-37m-arm-linux-gnueabihf.so
93

I added sudo, because when I donā€™t I get:
/usr/local/bin/python3.7 -m venv .
Error: [Errno 13] Permission denied: ā€˜/srv/homeassistant/includeā€™

I succeeded when i first switch to the homeassistant user first as mentioned here:

94

When I first wrote those instructions the first thing I said was it was all run as the homeassistant user.

95

Use pip install gi==1.0
Note the double equals sign.

Iā€™ve figured out how to update python without affecting the OS python installation, using pyenv.

Note: this will take a few hours of your time, between installing and building python and home-assistant.

Iā€™m using a virtualenv install of HA, running on a Pi 2. Building python took almost 30 minutes, + you will have to reinstall homeassistant (another 30 minutes). Donā€™t worry about your configuration files (backup just in case), this will install a new virtualenv, so after you test to make sure everything works, you can delete the /srv/homeassistant.

Second note: Iā€™m running Raspbian Stretch, and I understand Raspbian Buster is coming out in a few days, but I feel this will be a more maintainable installation of Hass. If this has happened once, it will happen again. Else, you donā€™t have to upgrade to Buster if you donā€™t want to. :man_shrugging:

Run 1-6 as your homeassistant user
sudo -u homeassistant -H -s

  1. Install pyenv, I did the Github version, so follow 1-5. (You can replace .bash_profile with .bashrc or .bash_aliases)
  2. (Step 6 from above^) Choose your python version and start installing. I used 3.7.3 and it took ~30minutes.
    pyenv install 3.7.3
  3. Install pyenv virtualenv
  4. Create a new virtualenv with your new python
    pyenv virtualenv 3.7.3 home-assistant
  5. Jump into this virtualenv
    pyenv activate home-assistant
  6. And install home-assistant again (~30 minutes)
    python3 -m pip install wheel homeassistant
  7. While that is installing, you can update your systemd, or other, config for Hass with a user with sudo powers. You can backup this file, to be safe.
    sudo nano /etc/systemd/system/[email protected]
    Change the ExecStart= line to ExecStart=/home/homeassistant/.pyenv/versions/home-assistant/bin/hass -c "/home/homeassistant/.homeassistant"
    Run sudo systemctl daemon-reload to make sure this change is registered with systemd.
  8. I had Hass stopped while I was doing this, but this should work once Hass is re-installed
    sudo systemctl restart [email protected]

If, like me, you are/were using venv, and was concerned with the upcoming Python 3.5 deprecation, despair no more: you can have a working solution using venv on Buster.

Raspian Buster was released on the 24th of June.

I was able to upgrade my RPi to it, and HA works.

To do this, here are the commands:

sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade

Then manually edit the following files, and change all occurrences of ā€˜stretchā€™ to ā€˜busterā€™

/etc/apt/sources.list and /etc/apt/sources.list.d/raspi.list

Then continue with the same commands as above :

sudo apt-get update && sudo apt-get upgrade && sudo apt-get dist-upgrade

Then reboot, and you have Buster.

Then you have to create a new venv, using Python 3.7 of course. Use the same method that you used to create the initial one.

One issue I found:

The logbook, recorder and history components do not work. Home Assistant says that they are missing dependencies.

I had them as MySQL under Stretch, but now Buster installs MariaDB.

Per the instructions under the recorder component, I need to install the pip mysqlclient. That fails because it cannot find the mysql_config command, which used to be part of libmysqlclient-dev. But the equivalent libmariadbclient-dev is missing this command.

The solution to the above is to do:

python3 -m pip install PyMySQL

Then in your configuration.yaml, change the db_url to:

db_url: 'mysql+pymysql://localhost/DBNAME?charset=utf8'

All works now.

It might be worth installing Raspbian Buster at this stage.

Personally Iā€™d just do a fresh install of Raspbian and Home Assistant and copy over config. It takes a little longer but will be worth it long term.

Thankā€™you very much!! Working very well. :v::v:
