E: Some index files failed to download. They have been ignored, or old ones used instead.

E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.

A quick help will highly be appreciated.

Thanks

You have a file that has invalid permissions that can be removed:

sudo rm /var/lib/apt/lists/partial/ppa.launchpad.net_webupd8team_java_ubuntu_dists_xenial_main_i18n_Translation-en.xz

You can also run this command to clear the apt cache:

sudo apt clean

After that your apt update command should work as expected.
