Maybe we should have a backup mirror to get those tools case they disappear from original link!

[xiaoxiang781216]

Yes, it's important to achieve the essential ci tools to the reliable place.

[pkarashchenko]

Possible solutions in either https://github.com/apache/nuttx/pull/9669 or https://github.com/apache/nuttx/pull/9672 @btashton which do you think is better to pick? I would suggest to pick both.

The issue here does not have to do with upstream disappearing.

[btashton]

The issue is triggering this is that we cache the homebrew install to make the install faster, but since not everything is pinned we run into issues if versions change. In this case is openssl. The patches @pkarashchenko proposed may be help, but in the end we may just have to not cache brew.
