My comment was referring to Arch Linux ARM, where packages related to python 2 fall under ‘pip2’. Since you have written ‘pip install pillow moviepy’ already I suppose that ‘requests’ should also go there: ‘pip install pillow moviepy requests’.
I’m not familiar with the package managment and naming in Ubuntu, however, but this is probably the case (since Seafile uses python 2, regardless of distro naming).
Glad to hear that it’s working for everyone. Likewise, thanks.
