The libraries/joomla/cache folder doesn't exist in Joomla 3.8. You will need to rename your current libraries folder and copy a fresh one from a Joomla 3.8 zip file. See here for a similar error.

The problem that you're having is very common when the update is done manually by overwriting the Joomla files and then "repairing" the database.
