Moving HA-Core from old to new PC

[mega-hz (Wolfram)]

Hello.

I have HA-Core 2023.1.7 running on my “old-PC”.
Now i want to move HA to a new PC.
For that i installed Debian11 and HA-Core, HACS, Cockpit and updated Python to 3.10.12.
HA is running now on the new System.

First question: Why does HA says, There is Python 3.9.2 even i just updated it to 3.10.12 ?

How can i fix this?

Second Question: Can i copy all the files like configruation.yaml, the folders and so on from old system to new system? Do i have take care of something special?

or

Third Question: are in the ha-backup also all integrations,frontends,automations included? Or do i have to reinstall them by hand?

Fourth Question: in HACS i can install Frontends, Automations but NOT Integrations!
When trying any Integration, the circle keeps on turning forever!

How can i fix this?

Thank you for helping…
Wolfram.

For that i installed Debian11

Why install Debian old-stable, and not the current stable version - Debian Bookworm, which has already Python 11 ?

Yes, make sure you copy the hidden files/folders as well

Some more people have seen this recently.

Well, first i installed Debian 12 but HA didnt install right, some errors.
So i took Debian 11. Later i can dist-upgrade…

But why does HA do not see Python 3.10 and shows 3.9.x?

[mega-hz (Wolfram)]

and one more thing i find strange:
Even i upgraded HA it shows me: Home Assistant 2023.1.7 Frontend 20230110.0 - latest

Shouldnt be there a higher Version of HA?

But why does HA do not see Python 3.10 and shows 3.9.x?

Because the venv was built with that version. You need to re-create the venv with the new version.

Also, you need Python 3.11(.5) now

@mega-hz

Second Question: Can i copy all the files like configruation.yaml, the folders and so on from old system to new system? Do i have take care of something special?

Yes, or restore the backups you’re hopefully taking.

@mega-hz

Third Question: are in the ha-backup also all integrations,frontends,automations included? Or do i have to reinstall them by hand?

Yes, they are.

Check your log file.

OK, i just upgraded to Debian12. It also update Python3 to 3.11.2.
You need to re-create the venv with the new version.
what is venv and how do i recreate this?

When i try to start HA it shows me a error:

I checked the path of HA with wheris hass and put it into /etc/systemd/system/[email protected]:

I also tried with

This is what Cockpit shows me about failure of HA:

What now?

@mega-hz

re-create the venv

ok, i got it running again following this threat:

Moving away from venv

@AaronCake I found that one as well. Using that page and a few other sites I made myself a procedure that works. Here are the steps that worked for me: Upgrading Python for VENV installs This was for Python 3.9 Install new version of Python sudo apt update sudo apt install software-properties-common sudo add-apt-repository ppa:deadsnakes/ppa sudo apt install python3.9 sudo apt install python3.9-dev sudo apt install python3.9-venv Backup HA and install new VENV mv /srv/homeassistant /srv/ho…

Now i also have the newest Version: Home Assistant 2023.8.4

So far so good…

Trying HACS Integration…
…still only turning circle

So 3 of 4 Problems are solved.
Where do i find the logfile of HACS?

EDIT: found it.

there is something:

2023-08-30 14:41:05.844 ERROR (MainThread) [custom_components.hacs] <Integration custom-components/ble_monitor> Download was not completed [[Errno 13] Permission denied: '/home/homeassistant/.homeassistant/custom_components/ble_monitor']

so i typed chmod -R 777 /home and now HACS Integrations Downloads working!

Next step is to restore the backup…

[mega-hz (Wolfram)]

said for HA not to have a Restore-Function for backups except before boarding…

[Tinkerer (aka DubhAd on GitHub)]

Only HAOS has a restore option, and you’re not using it.

@mega-hz

ok, i got it running again following this threat:

That’s not a good thread to follow. Using a venv is the only recommended way when you use pip.

By skipping the venv you’re at risk of breaking your HA install if you install any other Python program.

[mega-hz (Wolfram)]

HAOS is no option for me (not yet) because some other Software is running on that PC like Motion-Eye, Cockpit and some small tools.

BTW: the “Using a venv” describes exactly the way i did, so everything should be fine now.
After some Integrations-Update with HACS the new System is running well!
Everything is back there. Time to make a Disk-Backup…

I thank all for the help!

[Tinkerer (aka DubhAd on GitHub)]

Do keep in mind that when Python 3.12 is released you’ll need to install that and rebuild the venv with 3.12. Then again for 3.13, 3.14, etc.

Alternatively, use Docker and those problems go away.
