    Latitude 5411 no drivers for wifi or sound

    I have Installed Kubuntu 20.04 LTS on Dell Latitude 5411 laptop (https://certification.ubuntu.com/hardware/202002-27717) but unfortunately there are no sound and wifi card drivers installed. Weirdly wifi was working for sure during the installation process. Looks like something wasn't installed properly. How can I fix it?

    Post the output from 'lspci' command here so that people can make suggestions to fix your issue - it is possible that your laptop may actually contain different hardware?

    Seeing as how it's very new hardware (Comet Lake), you should try the newer HWE kernel before anything else:
    Code:
    sudo apt-get install linux-generic-hwe-20.04
