Problem updating from 14.2 to 15.x

Hello,

Unfortunately, I don’t know which topic is right, I didn’t find anything suitable when searching.

I would like to update from 14.2 to the current 15.2. Unfortunately, the update does not work, I have already tried it with 15.0 and 15.1.

I click on install and HA installed and restarts- no change- I’m still at version 14.2

Everything currently runs on a mini PC with Intel processor.

How do I get the update installed?

Same issue here. On RPi4.
