It doesn’t work
Should i type it on terminal addon in HA ?
this is covered in the original post.
The guides are in the 1st post of that thread, there is also useful information in that thread from people who have had to work out how to do what you’re trying to do. Everything you need to know is there.
I’am stucked
Can’t install the addon
Will try this evening with a keyboard and monitor, i hope it will work 
It mentions that in the post too.
So your only option is a direct attached keyboard and monitor.
I have to scratch… Even my backups are corrupt 
You can still do the manual update via an attached keyboard and monitor.
Then you need to work out why your backups aren’t working.
Yep and without any adapter mini hdmi, i have to do it in blind mode
enter → prompt → login → enter → pass → enter → command line → enter and wait 10 min to be sure before restart
is this correct ?
There’s no restart required really. Can if you want to but the watchdog brings supervisor back online with the working image after the command completes.
But if you have no way to see the screen at all you might want to try setting up host ssh. Or if you have a way to connect via uart that works too.
