I am running HA 2021.11.5 Core in a Ubuntu 20.04 container on a Proxmox 7 server. Since last upgrade i got a notification on HA: i need to upgrade python to version 3.9 to be able to upgrade to the next HA version in 2022.
Since then i attempted several times to upgrade to python 3.9 in several ways i found on google and here on the board. None of which worked without one or more problems.
I figured i bypass the python problem and setup a new HA system with the latest Ubuntu 21.10.
I would like to know how to backup and restore the current HA setup i want to keep on using.
Is it enough to backup /home/homeassistant/.homeassistant and install HA core in the new system and just copy that folder into the new system?
Backup the configuration folder and put it back on a new clean Ubuntu system, like @tom_l said, didnβt work either. I will try your suggestion soon and let you know if it worked.
What a pain to upgrade python and keep your current HA configuration.
