The service does not load

Configuration

I sent HA to reboot, after it did not start, how to find out where the problem is?

You’ll need the full log, which journalctl gives you.

It’s possible that your problem is a corrupted SD card, which is most likely caused by a low quality power supply.

Often there are such errors

It’s possible that the system itself works, but because of poor power supply, some services do not work?

It could be a faulty SD card, but it could also be that the power supply doesn’t sustain 5V, but drops below, or that it can’t sustain the amps required.

At this point, it’s time to back up and restore to a fresh card. While that fresh card is in use you can check to see if the SD card is ok, and if it is then the problem is with your power supply.

Thank you very much I will try.
Can I copy the whole memory card, except for HA there a lot of useful installed?

You could, but you’ve got an unknown amount of corruption there. I’d highly recommend you do a fresh install and copy across the configuration files only.

I’d also suggest you invest in, and test, a backup process. It could be anything as simple as running rsnapshot to a locally attached USB drive, to (more sensibly) backing up to either a remote host or an online service.
