It’s a water level indicator, made for hydroculture setups.
I use LECA (expanded clay pebbles), which are constantly standing a few centimeters high in nutrient water and are moist all the time.
I only have to water every few weeks because of that, and the indicator tells me when to water again.
Here’s a post I made about that setup if you’re interested, including a schematic. Sadly only in German.

You did everything right. Boot into the image that works, and then apply
rpm-ostree rollback
. This reverses the broken image and the working one, so you’ll boot into this one the next time you boot up until you change something in the order, e.g. by updating.In the meantime, wait a day or so and then update again.
On what channel are you on?
