May be I missed something ?

What's the output of

ls -la /opt/homebrew
ls -la/opt/homebrew/bin

?

It looks like you might have a partial Homebrew installation. What's the output of /opt/homebrew/bin/brew config and /opt/homebrew/bin/brew doctor?

[namlegief]

I deleted all from /opt and issued the installer again . It looks good now . Thanks a lot

[Sudhanshujha10]

how did you deleted all

[maestroh1git]

Im having a sort of similar issue; except it involves git

this is it

You probably have an insteadOf setting that's rewriting GitHub https: URLs to git: or ssh: form, git config -l | grep -i insteadof should show you what it is. Remove that config setting, then run the installer again.

[maestroh1git]

How do I remove the config setting?

amaku@Davids-MacBook-Pro ~ % git config -l | grep -i insteadof
url.git://github.com/.insteadof=https://github.com/
url.git://.insteadof=https://
url.https://.insteadof=ssh://
url.https://github.com/.insteadof=git@github.com:
url.https://github.com.insteadof=git@github.com:
url.https://github.com/.insteadof=git://github.com/
url.https://github.com/.insteadof=git://github.com/
url.git@github.com:.insteadof=git://github.com/

[gromgit]

The most likely file to edit would be ~/.gitconfig, though I'd encourage you to read the FILES section of the git-config(1) man page (man git-config), which documents all the possible locations where your insteadOf directives could be.

I'd also strongly recommend first removing all the insteadOf directives you find, then think carefully about what really needs to be rewritten. To be blunt, that's a mess you have there.

[carlocab]

You can try

git config --list --show-origin | grep -i insteadof
