Question: I'm struggling to brew install minikube. I don't have any version, but need an older version. I'm trying the familiar way, but get an error:

```
~ brew install minikube@1.18.1
==> Searching for similarly named formulae...
Error: No similarly named formulae found.
Error: No available formula or cask with the name "minikube@1.18.1".
==> Searching for a previously deleted formula (in the last month)...
Error: No previously deleted formula found.
==> Searching taps on GitHub...
Error: No formulae found in taps.

```

I've tried to do a bit of homework, but still errors:

```
~ brew install https://github.com/Homebrew/homebrew-core/blob/8d37c361ee69503961a3010e7896f6ecf8d3a059/Formula/minikube.rb
Updating Homebrew...
==> Auto-updated Homebrew!
Updated 1 tap (homebrew/core).
==> Updated Formulae
Updated 16 formulae.

Traceback (most recent call last):
`brew extract` or `brew create` and `brew tap-new` to create a formula file in a tap on GitHub instead.: Invalid usage: Non-checksummed download of minikube formula file from an arbitrary URL is unsupported!  (UsageError)
`brew extract` or `brew create` and `brew tap-new` to create a formula file in a tap on GitHub instead.: Invalid usage: Non-checksummed download of minikube formula file from an arbitrary URL is unsupported!  (UsageError)

```

This must be elementary, but I can't seem to figure this out :(

Answer: 
`$brew update-reset`

This helped me with the error.
I think first you can try to run 'brew install minikube' only, see if you can successfully install it or not. If no error then it's probably your version issue. If still has Error then that might be your local home-brew issues, then you can Try to run 'brew doctor', based on the warning and Error info search in stackoverflow you probably will find out the answer.
