Installation

sorry for the bad English...

my problem is that since OS version 13.1 I can't update to 13.2; 13.3 etc.
now it started to say:
Unsupported system - operating system version

when I update it always says that it is installing then it restarts but it still says that it is version 13.1

Home Assistant OS installation method
Core 2026.6.2
Supervisor 2026.06.1
Operating System 13.1
Frontend 20260527.5

HA runs in KVM virtual machine

PS: when I had problems installing 13.1 on 13.2 I definitely wrote somewhere but no answer....

worst comes to worse, take a full backup (make sure you have the encryption key, or disable encryption), re-install latest haos, and restore backup :wink:

In my opinion, this is not a solution because I personally think, and probably when I finally have time, I will confirm that the OS upgrade will not work again…

If an OS install ends with the old OS then it means it tried to install, had problems booting the OS and switched back to the partition that did work. The logs should be able to give you a clue what went wrong booting the newer release.

When you do a fresh install and restore a backup it is a very different process than an upgrade. So it will probably not fail the same way the upgrade does.
