How To fix Can't update or upgrade Homebrew

Question

I can no longer run either brew upgrade or brew update: both abort with

Error: homebrew-core is a shallow clone. To `brew update` first run:
  git -C "/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core" fetch --unshallow
and if I follow this suggestion and run git ... --unshallow

and if I follow this suggestion and run git ... --unshallow and then try brew update or brew upgrade I still get the same error message.

If I then try the command again (maybe I didn't do it right the first time?) I get

fatal: --unshallow on a complete repository does not make sens`e

How do I get past this error message to run brew upgrade or brew update without errors?

Please Help me i was tired Thanks!

you mean, you run `git -C "/usr/local/Homebrew/Library/Taps/homebrew/homebrew-core" fetch --unshallow`, and you still have the issue? — chenrui, Jan 02 '21 at 22:29

Basically if you see the following error then run what is suggesting you, but could take some time maybe between 5 and 10 minutes depending on how fast is your system:

Error:
  homebrew-core is a shallow clone.
  homebrew-cask is a shallow clone.
To `brew update`, first run:
  git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core fetch --unshallow
  git -C /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask fetch --unshallow

I hope that answered your question to you or someone else, good luck.
