sudo rm -rf /var/lib/apt/lists/*
sudo apt-get update
sudo apt-get upgrade

and then again trying to upgrade from software upgrade GUI It again fails with the same issue mentioned above How can I fix this issue?

    It means the file contents isn't what it should be. Double-check that your internet connection is good, and, given a hash mismatch, do this on a private/trusted network do decrease the risk of this being an MITM attack. See if it still happens on a private, trusted, and reliable network. – cocomac Jan 09 '22 at 05:36
  • @cocomac my internet is working fine, i did try it multiple times, mine is a private local internet provider, not sure what exactly is the issue – Rajat Rao Jan 09 '22 at 05:38

    Maybe change where it downloads from on the Download from: in the Software & Updates. Maybe try the Main Server. – Terrance Jan 09 '22 at 06:16
