I think this is a problem in Google Colab. Please run the following line in a fresh Colab:

!sudo add-apt-repository ppa:ubuntu-mozilla-daily/ppa

It should give you the same error:

Traceback (most recent call last):
  File "/usr/bin/add-apt-repository", line 363, in <module>
    addaptrepo = AddAptRepository()
  File "/usr/bin/add-apt-repository", line 41, in __init__

I have encountered the same problem. I think this is because Colab just upgraded their default runtime to Ubuntu 22.04 LTS. One can access the old 20.04 LTS runtime (available until early August) from the Command Palette via the “Use fallback runtime version” command and it works.
