I am trying to load HA on to a RPi4-B with a new scsi ssd 232G. I down loaded (RPi Imager Picker) HAOS 18.0 and it doesn't seem to include Advanced Options like Supervisor, Add-ons and/or Terminal.
This should be straight forward.... not sure what I'm doing wrong.
Any advice and/or ideas would be appreciated.
Just for the heck of it, I just tried using a 64G SD card and that failed to load Advance Options too. It’s supposed to be an option under your profile to turn on/off, but it’s not there.
Just for info add-on’s are now called Apps available from settings > Apps. Just in case you are looking in wrong place.
It was removed a while ago. That is no longer an option. Nothing is hidden.
What documentation did you follow? I hope it wasn't outdated AI slop.
There may be issues with the current 18.0 release for your scenario. I strongly recommend you dig a little further before stumbling, as these have been carefully documented in other threads here on these forums as well as GitHub and are actively being solved.
Sounds like you are using an old guide.
Supervisor is not in the menu anymore, AFAIK.
Addons is renamed to Apps.
Advanced user have been removed.
In general guides older than 6 months should be regarded as outdated with HA, due to the speed this project is moving at.
The forum is the best place for updated information, other than the documentation of course.
Even asking for an up-to-date guide is better answered in the forum. 
Wow - I spent so much time trying to find this. Thank you!
