I have tried doing following

sudo apt-get clean
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 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

Maybe change where it downloads from on the `Download from:` in the Software & Updates. Maybe try the Main Server.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
