Can anyone please help here

Answer 1

I have faced that same issue, and one way around it is to install directly from the GitHub release.

For robotframework, it appears that version 4.1.2 is the last release that supports [J/P]ython 2.7, so you would install it by running the following command:

jython -m pip install https://github.com/robotframework/robotframework/archive/refs/tags/v4.1.2.zip

And that should do it.
