Trying to use the Mozilla bootloader to install Fennoc Opensource, but get an error

Question

I am trying to download a source for Fennoc, a Mozilla andriod client, as a fun project to learn something about the development of Andriod.

I use this Curl command from mozilla to start the bootloader:

curl -O https://hg.mozilla.org/mozilla-central/raw-file/default/python/mozboot/bin/bootstrap.py && python bootstrap.py

However, I keep getting this error:

We tried to install the following Android packages:
tools
But it looks like we couldn't install:
tools
Install these Android packages manually and run this bootstrapper again.

I tried downloading Android Studio to manually download all the SDK items, as Bootstrapper recommends, but continue with this error. A full trace below any help is appreciated!

EDIT: This is believed to be the relevant part of the python script:
