You must always follow the reporting bugs guide. When you opened this issue, the template in place urged you to do so and gave you the relevant links.

Closing, since this issue doesn’t even contain any information.

[palindrom615]

I'm so sorry about that. I pressed enter mistakenly.

[vitorgalvao]

What’s the output of ls -la "${HOME}/Library/Caches/Homebrew"?

[palindrom615]

This is some part of output of ls -la "${HOME}/Library/Caches/Homebrew". Maybe no need to paste all of them...

There's your problem. Why is this directory owned by root? For that matter, why are several of your Homebrew bottles owned by root?

Just sudo chown -R "${USER}:staff" "${HOME}/Library/Caches/Homebrew" and try again.

[palindrom615]

I sometimes used brew as su and maybe that's why. It solved! Thanks very much!

Yup, that's why. Don't do that! :wink:
