Investigate and fix that. ensure mn-wifi install on ubuntu 24.04 LTS. I'll work on this.

Maybe replace by python3-pep8 https://packages.ubuntu.com/search?keywords=python3-pep8

I ran into the same issue recently. Here's the solution that worked for me:

  1. Open the terminal (Ctrl + Alt + T).
  2. If your mininet-wifi is in the home directory then copy-paste this command --> cd mininet-wifi/util (OR) Navigate to mininet-wifi directory in your machine via terminal and then change directory to util.
  3. Type --> gedit install.sh
  4. Click on the hamburger icon (three horizontal lines) next to the save option.
  5. Select 'Find and Replace'.
  6. In the 'Find' field, type --> pep8. In the 'Replace' field, type --> pycodestyle.
  7. Click 'Replace All' and save the file.
  8. Navigate back to the mininet-wifi directory by typing --> cd ..
  9. Everything is all set now. Ensure you are in the mininet-wifi directory and verify if the command works --> sudo util/install.sh -Wlnfv

Explanation of the Issue and Resolution:

The pep8 package was previously used to check Python code against the style conventions in PEP 8. It has since been replaced by pycodestyle, which is why pep8 is no longer available as an installation candidate in Ubuntu 23 and higher.

We resolved this by replacing all instances of pep8 in the install.sh file with pycodestyle. This ensures that any functionality related to pep8 required by mininet-wifi is now directed to pycodestyle.
