⚠️ ⚠️ ⚠️
@pierremonico Can you update your gist to

1. Use some other directory than /opt/, since we have seen people having permission issues in this location. Because there is no write permission, auto-updates does not work when installed in this directory. Here's the link to the issue that people are facing because of this postmanlabs/postman-app-support#5039
2. Include the information that 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

Also, the gist from where this was forked has been updated accordingly https://gist.github.com/aviskase/e642248c35e400b56e2489430952369f

the path for the icon is now:

/opt/Postman/app/resources/app/assets/icon.png
