Honestly, when reading some of your messages on #2481, I was concerned you were going to think you could do this (lol ;P). The files in the Android SDK are managed by a package manager, and the side-by-side NDK is not exactly the same managed object as the NDK package.

As far as I'm concerned, the correct strategy to is to just not install ndk-bundle and instead just install the intended side-by-side NDK for the LTS. Like, I'm pretty sure the NDK package--the one that goes in ndk-bundle--is literally marked as "Obsolete": do we really need it? ;P

This is causing warnings during install of side-by-side packages, but might also (I'm not sure: I was going to finish investigating this today and then type up a better bug report, but I accidentally hit enter on the title field and that apparently caused the issue to submit) be causing errors installing side-by-side NDKs?

Since I'm getting this SSL error also, I'm not sure (and now my mac builds are all just being queued and aren't going through so I can't even test this this morning to try to better isolate what is happening, but I've been getting this install error over the course of three days now).
