    ubuntu 16.04 update error: source list outdated

    Hello all,
    Greetings.
    I have not managed to update internet for sometimes.

    Code:
    Step 1: sudo apt-get update. below is part of output.

    W: Some index files failed to download. They have been ignored, or old ones used instead.
    E: The package lists or status file could not be parsed or opened.
    Can I delete the source files and create a new one? any help much appreciated?
    In /etc/apt/sources.list, there are two files:
    1. source.list
    2. source.list.d
    which one to work on?

    If you want to hand-edit your distro-specific repo source list the correct file is /etc/apt/sources.list

    The sources.list.d folder should contain individual user-added repos that may also need to be updated.

    source.list is a file with standard software sources. source.list.d is a directory with additional source lists.

    Ubuntu 16.04 reaches end of life this week. Your software sources will no longer work (some PPAs have already stopped working). I suggest you plan an upgrade. A fresh install of 20.04 may be cleanest.
