uninstall script not running on M1 migrated from Intel

[quickdry]

I migrated my old intel Mac onto an M1 (migration assistant, not timemachine). It brought over the intel homebrew installation and I'm trying to remove that and do a new fresh install.

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

Gives the error:

/bin/bash: line 236: /opt/homebrew/bin/brew: No such file or directory
Failed to locate Homebrew!

which is what i'd expect as this has never had an M1 version of brew installed. I can uninstall all the packages and casks, but that still leaves brew. How do I remove that final piece of the puzzle properly so I can start fresh? (is ther a flag to force it to think it is only on an intel and not fail with the /opt/homebrew check?) The documentation I could find all seems to start from the POV of having no brew installation, or that the uninstall script just works.

Try the following:

PATH=/usr/local/bin:$PATH arch -x86_64 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/uninstall.sh)"

This "fakes out" the uninstaller in two ways:

1. Ensures that the Intel Homebrew path takes precedence, for when the uninstaller asks "which brew would normally be run?"
2. Ensures that the uninstaller is run in an Intel context

In that case you don't have a rosetta brew install so there is nothing to uninstall.

I kept getting

/bin/bash: line 242: /usr/local/bin/brew: No such file or directory
Failed to locate Homebrew!

After much research I was finally able to figure out that my Homebrew was indeed not located there...
this is the line that worked for me
/bin/bash uninstall.sh --path=/usr/local/Homebrew
