How to Solve Error Permission denied when running brew cleanup

Error Permission denied when running brew cleanup

When I try to run `brew cleanup` I get:

Warning: Skipping atk: most recent version 2.34.1 not installed

Error: Permission denied @ apply2files – /Users/iuliaulialiaia/Library/Caches/Homebrew/.cleaned

I can neither run other commands that uses `brew cleanup`, like `brew upgrade`:

P.S.: I cannot run homebrew as root:

Error: Running Homebrew as root is extremely dangerous and no longer supported.

As Homebrew does not drop privileges on installation you would be giving all

build scripts full access to your system.

At some point, I believe homebrew was suggesting one change the ownership and group of /usr/local to $(whoami):admin — which is what I have set (in Mojave) and homebrew just works for update, upgrade, and cleanup. A bit more of a PITA on Catalina though.

 

Guessing you are running Catalina then! It’s changed the permissions model which has broken lots of stuff 🙁

This should work:

sudo chown -R $(whoami):admin /usr/local/* && sudo chomd -R g+rwx /usr/local/*

Then try brew cleanup

 

The second command has a typo, it should be chmod instead of chomd

sudo chown -R $(whoami):admin /usr/local/* && sudo chmod -R g+rwx /usr/local/*
