So it's been a while since I updated my Pi-hole. So today when I tried several times to update I was able to update Pi-hole and the web interface, but not FTL. I tried all the tricks, but I keep getting the same error and notes.

I assume this could be due to the resent 5.9.0 release, is that the case?
And if so, how do I get around the 5.8.1 error to the new release?
