    Ubuntu 20.04: WIFI shows up, but will not connect to internet

    I updated to Ubuntu 20.04 from 18.04. I have the WIFI light on the desk top with 4 bars, but I cannot connect to the Internet.

    How about sharing the wireless-info.tar.gz as an attachment to your reply so that we may examine it?

    Re: Ubuntu 20.04: WIFI shows up, but will not connect to internet

    You have many errors.

    http://ppa.launchpad.net/cairo-dock-team/ppa/ubuntu/dists/


    PPA's are 3rd party sources, so all security checks are your responsibility. You should check they are trustworthy, still maintained and good for your system. I see errors for that PPA which does not support releases after 15.04, thus provides no support for focal/20.04 & should not have been added. It should be removed.

    W: Target Packages (partner/binary-i386/Packages) is configured multiple times in /etc/apt/sources.list:45 and /etc/apt/sources.list.d/xenial-partner.list:4

    You have duplicate entries, the error message tells you the file & lines where the entries can be deleted. The directory `/etc/apt/sources.list.d/` is empty for a new system, so entries there were added by someone post-install with `sudo` rights. Removing the duplicate entries will remove these warning messages.

    Open the file browser and click 'Name' to sort the files in your Home directory alphabetically. In the W's you will find wireless-info.tar.gz.



    Attach it to your reply, please.
