When doing

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

I get

==> Downloading and installing Homebrew...
/bin/bash: line 604: cd: /opt/homebrew: Permission denied
/bin/bash: line 604: return: can only `return' from a function or sourced script
/usr/.git: Operation not permitted

This is on M1 Mac mostly fresh install expect for zinit and command line tools.

What does ls -al /opt/homebrew or ls -al /opt/* show you?

[OKNoah]

What's the output of ls -ld@eO /opt/homebrew?

naru@Narus-Pro ~ % ls -ld@eO /opt/homebrew
ls: /opt/homebrew: Permission denied

[gromgit]

Huh. How about ls -ld@eO /opt?

That's not right at all. Did you happen to do a chmod -R 644 /opt or something similar at some point?

Anyway, to fix this, do the following:

find /opt -type d -exec chmod a+x {} +

then run /opt/homebrew/bin/brew config and /opt/homebrew/bin/brew doctor to see if you now have a working Homebrew setup.

find /opt -type d -exec chmod a+x {} +
find: /opt: Permission denied

[gromgit]

That error says find can't even read /opt. What's the output of /bin/ls -lde@ /opt?
