Ha os update not working for downgrading

[F1am]

After updating to HA OS 6.0 I wanted to revert to a previous version (found serious bugs), but the command
ha os update --version 5.xx

gives me the following error for any version:
Error raised from OTA webserver: 404

How can I solve this?

ha host update --version 5.13

EDIT: This is wrong.

It’s ha os update --version 5.13

Thanks for the very quick answer,
ha os update --version 5.13
works

Interesting. That must be a legacy command left in for backward compatibility. The currently documented command is definitely ha host update See: https://www.home-assistant.io/common-tasks/os#host

Yeah I was a bit confused, I will stick with ha host update for now on.

“host update” is an alias to “host reload”, see host update --help

[tom_l]

Well crap. That was bad advice. Sorry.

Ok, so I want to revert to 5.4 (the only stable version for me). The command

ha host update --version 5.4

Gives me an error, since flag --version does not exist
ha os update (the one I used in the past) only works for 5.13

[tom_l]

Yeah I was wrong. The command is ha os update

You can still downgrade with USB https://github.com/home-assistant/operating-system/blob/44cca729f0d3e91614965deb87429a123c4050b8/Documentation/configuration.md#automatic
