For Debian use this command: apt-get install -y build-essential zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libsqlite3-dev libreadline-dev libffi-dev curl libbz2-dev libmysqlclient-dev libjpeg-dev libtiff5 libopenjp2-7 All commands are meant to be executed as a regular user except those executed with sudo.įirst we will install some required packages. The idea is install our new python version using altinstall, so we maintain our main python version to not broke any dependencies on our system. You could upgrade to python 3.9 as well only changing the sources to download. This procedure has been tested with both. Those distributions provide python 3.7.3 at a maxim. This procedure is for those that use Home Assistant core installed in a virtual environment and do not have python >= 3.8 provided by their distribution, Raspberry PI OS and Debian Buster included. With the announce of the 0.116 version we have seen that python 3.7 will be deprecated, probably in version 0.118. Anyway I have tried to do the upgrade in the least possible intrusive way, so we can rollback to our last state if something goes wrong. I encourage to take a full backup of your Home Assistant, configuration and database before starting. This is my own experience, with some minor problems that I will explain later, yours could be different.

Here is how to upgrade a Home Assistant instance to python 3.8.6 using python virtual environments.
