I have the similar issue while adding repository for ubuntu:

$ sudo add-apt-repository https://klen.github.io/python-mode/deb main
Error: need a single repository as argument

and if I remove the main then:

$ sudo add-apt-repository https://klen.github.io/python-mode/deb
$ sudo apt-get update
Ign:6 https://klen.github.io/python-mode/deb bionic InRelease

  404  Not Found [IP: 185.199.109.153 443]

@python-mode is not under klen github anymore for a long time. You won't be able to use such way to install python-mode. Please, refer to our README to check possible ways to install python-mode (there is not apt alternative!).
