Answer 1

Running xcode-select --install attempts an install, but fails with the following error: Can't install the software because it is not currently available from the Software Update server. Here's what worked for me.

OS: Catalina 10.15.6
Xcode-select version: 2373

NOTE: Before running all this, I already had xcode-select version 2373 installed. But removing and reinstalling fixed the issue.

1. uninstall xcode-select

sudo rm -rf $(xcode-select -print-path)

2. Go to the app store, and download XCode.

3. Open XCode. On initial load, it will update/install stuff. let this happen.

4. From Apple Developers, manually download Command Line Tools for Xcode 12

5. Install the CLT for Xcode 12 package.

You should now be good to go.
