After receiving numerous reports from multiple users, we decided to investigate the issue and devised a set of solutions to fix it completely. Also, we looked into the reasons due to which it is triggered and listed them as follows.

    cd /var/lib/dpkg/info/
  2. Delete the following files manually.
