How to solve "duplicated database entries" with pacman

pacman-fix-tip.md

• Ensure that no .pacnew files exists in the system
• Get the list of duplicated package entries, store it in a file named duplicateNames.txt
• Execute this script as root

extraEntries="`\
	for name in $( cat duplicateNames.txt ) ; do
		ls $localDb | grep $name | sort | sed 1d
	done
`"

cd /var/lib/pacman/local
rm -rf $extraEntries

• Perform a full system upgrade, expect some errors
• Deal with eventual .pacnew and .pacsave files
• Perform another full system upgrade to ensure everything is fine
