Upgrade Python 3.9 for Home Assistant Core

In my Home Assistant Core, a notification informs me that from version 2022.1 it will be necessary to update python to 3.9.
I try to do this, but after three days of work I haven’t succeeded yet.

I used this:

wget https://www.python.org/ftp/python/3.9.7/Python-3.9.7.tgz
tar xzvf Python-3.9.7.tgz
cd Python-3.9.7/
./configure --enable-optimizations

The output error:

myreadline.c:(.text.exit+0x0): undefined reference to `__gcov_exit'
collect2: error: ld returned 1 exit status
make: *** [Makefile:602: python] Error 1


What is your Linux distribution + version?

I’m sorry! I was so focused that I forgot it: Raspberry Pi4 4gb with raspberry OS buster

I see some pointer that removing “–enable-optimizations” might workaround the issue.

Tried the first day, but it doesn’t work.
I have already tried all the solutions found on google. I cannot understand the error.

this is my make output when I use “./configure” without --enable-optimizations:

I have worked on my All In One installation trying to upgrade Python with the same lack of success for 3 days also. I tried to move my system to Docker several times with no success either. I know I did a upgrade before moving from Phthon 3.7 to 3.8 but I can’t find that procedure. Any help would be appreciated.

To install 3.9:

Python 3.9 is not available by default in Ubuntu repos so:

#Add repo

sudo apt install software-properties-common
sudo add-apt-repository ppa:deadsnakes/ppa

sudo apt-get update

#Check 3.9 available
sudo apt list | grep python3.9

#Install 3.9
sudo apt-get install python3.9

#Add 3.9 to the versions of Python available. Ubuntu will try to use 3.6/7 by default 
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.7 1
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.9 2

#Now configure system to use 3.9 as default.
sudo update-alternatives --config python3

Choose 2

To confirm 3.9 being used:

python3 -V

Here are the steps I used for the upgrade to 3.7 many moons ago. Not tried it yet and will try to update to 3.9 later next week, but feel free to give it a go. I have amended it for 3.9

systemctl stop [email protected]

apt update

apt install python3.9

apt install python3.9-dev

apt install python3.9-venv

cd /srv

mv homeassistant homeassistant_old

mkdir homeassistant

chown homeassistant:homeassistant homeassistant

sudo -u homeassistant -H -s

cd /srv/homeassistant

python3.9 -m venv .

source bin/activate

pip install --upgrade pip

python3.9 -m pip install mysqlclient

python3.9 -m pip install homeassistant

pip install home-assistant-frontend


systemctl start [email protected]

journalctl -f -u [email protected]

Running in Ubuntu 18.04 LTS and I use an external MySQL database.

As I say none of this is tested yet, but I can’t see why it won’t work.



EDIT: just saw you are using RPI OS - this should work on that too - I will check on one of my PIs later.

EDIT2: Just ran all the above against my Ubuntu Core install and all is good. The only issue I had was that in my service file I had pointed to a different path (when I upgraded from python3.6 → 3.7) rather than /srv/homeassistant - once I corrected that all was good in the hood :slight_smile:


Just bumping this with the upcoming deprecation of 3.9. This should still work for 3.10 for those using core.

For Python 3.10.9 on Raspberry PI OS ( Debian based) I had to manually download and compile Python, nothing available via apt…

  • Download TGZ
  • ./configure --enable-optimizations
  • make altinstall

Instead of renaming the current folder for homeassistant on major updates I usually create a new folder , make homeassistant-user the new owner, sudo to user homeassistant and then follow instructions for a new core install, after pip finishes the install, I shutdown the existing Homeassistant, alter folder in systemd-file (don’t forget daemon-reload!) and start the new Homeassistant. Takes quite a while do download all the dependencies, better plan for up to 1 hour downtime.
Not a big difference compared to your instructions, only that I do make any modifications to the old Homeassistant installation.
I case something goes wrong, point the systemd-file back to the old installation and restart while trying to figure out what’s wrong…

Yep I haven’t tested, but should work on Ubuntu.

I tried doing this and got the following error “modulenotfounderror no module named ‘encodings’”

Any suggestions?

you got this error when you compiled and installed python 3.10 or after that when starting the python environment?
What hardware and OS are you using?


During compile. Raspberry Pi 4 with Raspberry Pi OS Kernel version: 5.15 Debian version: 11 (bullseye). Thanks.

Can you show output from the compile process, perhaps the last 15-20 lines prior to the error?
You did:

  • download tgz from python.org
  • extracted into new folder, for example into user “pi” home folder
  • ./configure --enable-optimizations
  • sudo make altinstall

Some instructions to compile Python on the Raspberry say you have also to install some Development dependencies prior to the compile process, I didn’t have to for 3.10, but might have done that already when compiling Python 3.8 or 3.9 on the same Raspberry

Just ran this on a spare pi 4 (lol really I have a SPARE pi4 in the current climate) and it worked fine.

Also referenced this link to do the same as @armin-gh

I now run HA in docker so can’t confirm that this works with the new release, but it will update your python to 3.10.x


What locale does Your system have?
Best, JR
TBH stumbled on ‘no encodigs’ with non en-US locale, under en-US Pyton 3.10 built OK but I had HA UTF-8 problems afterward- despite switcing locales :frowning:

Is necessary to destroy and recreate the virtual envs when running ha on venv?

And it is so for every minor version, like 3.13, 3.14?

I create a new VENV with every minor Python release ( minor like in 3.9, 3.10, 3.11 ) and keep the old venv -Folder as backup. Into the new VENV I install a new home assistant. I tried to update a VENV once ( If I recall correctly it was from 3.8 to 3.9), but that failed somewhere in the dependencies and I decided it is not worth my time to find out what could be possibly wrong with the update.

Compile new Python, create a new VENV, install HA, this can be done while your HA is still running. Then stop HA, change the systemd-file to point to the new VENV, systemd daemonreload and finally restart HA . Remaining dependencies are pulled, plan with 20-60 minutes downtime depending on your hardware and internet connection.

You won’t have new Python releases that often, I’ll update next time when 3.11 becomes mandatory.

I have not yet updated a VENV for Python Point releases



I think this has been answered perfectly above by @armin-gh !

I do exactly as he mentioned above!

As expected, things are never that easy:
