Duplicate files, in Layman’s term, are the files which are exactly a copy of one another. For example, if we have two files biz A and B; A would be a duplicate of B if it has the same content as file B. Duplicates are generally unavoidable. No matter what you do, you would always end up getting a few of them. Going through the whole file system and finding them one by one is a tedious job.

So, the easiest solution for me was to delete files that are not owned by pacman and blocking the upgrade process.
