Happened to me the same. Started downloading the update, asked to restart but when i restarted the phone went to the recovery mode. After restarting from this point nothing changed, everything stayed the same on Android 7.1.2. Just noticed that the "Other" folder was 1.8GB instead of almost empty. Had to format the sd card as internal storage to return that folder to normal. After this no more notification for an update to android 8. (Portugal here as well)
