That’s quite a long upgrade chain; 159 was released August 18, 2021.
You might suffer from a too small /boot partition due to the kernel growing regardless of the exact error you are seeing. In these cases, a backup and reinstall is usually needed. I personally have a couple of 162 systems that will need complete reinstalls due to this. Remember to also back up package settings, if you have any. A reinstall will likely be much faster than trying to fix the error.
