Please do not use this gist nor the above-linked blog post. We have seen users having issues when following similar instructions. There is no write permission in /opt/ directory. Please use the home directory or any other directory where write permission is there.

Also, Postman now supports auto-updates, and people should be using that instead of manually updating the app

More details:
The problem with using the command sudo tar -xzf postman.tar.gz -C /opt is that it does not remove the old files, just put the new files over the old. Doing this might make the Postman end up in an inconsistent state leading issues which are very difficult to debug and fix
