brew installation failure on macOS Monterey 12.3.1

[gshults]

How do I recover from the following installation failure?

I'm on a 16" 2019 MacBook Pro. I did a copy/paste of the following command:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

The installation finished with the following error:

Updating files: 100% (6359/6359), done. HEAD is now at ff34638b32f gloox: update 1.0.24 bottle. Error: Failed to link all completions, docs and manpages: Permission denied @ rb_file_s_symlink - (../../../Homebrew/completions/zsh/_brew, /usr/local/share/zsh/site-functions/_brew) Failed during: /usr/local/bin/brew update --force --quiet

I've attached the complete install log as a .txt file.

What's the output of ls -laR /usr/local/share/zsh?

There's your problem: the zsh directory and everything under it is owned by root. If the Mullvad VPN installer asked you for your password, that's the likely culprit that created all that as root.

sudo chown -R gerrie: /usr/local/share/zsh, then run the installer again just to be sure.

Success!
Thank you very much!
