I tried

brew cleanup && brew update

but not worked

Answer 1

I had the same problem with MongoDb. I was able to fix it first I changed the permission to admin.

Then I ran

brew cleanup && brew update

After that I ran

brew install mongodb 

and it worked like a charm

Answer 2

I also tried brew cleanup and brew update but still got the same issue so i did this

brew edit <application>

and replaced sha256 value with actual value shown in error msg.

and this worked out for me, hope it helps you too.
