Homebrew installer hangs while installing CommandLineTools on macOS Catalina

Question

I'm trying to install Homebrew onto an Intel MacBookPro (macOS Catalina), but while running /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" in Terminal, it seems to hang while installing CommandLineTools (the specific line it hangs on is ==> /usr/bin/sudo /usr/bin/touch /tmp/.com.apple.dt.CommandLineTools.installondemand.in-progress).

I already have a full install of Xcode 11 on this machine (which from what I have heard installs Xcode CommandLineTools).

After navigating to /tmp, I found that it did successfully run touch and create the file described in the command it ran, but never wrote anything to it.

I waited for about an hour with no avail. Here is the log:

Answer 1

I'd reinstall Xcode command line tools:

1. sudo rm -rf /Library/Developer/CommandLineTools
2. xcode-select --install
