Dear users,
The hardinfo project has not be maintained in a long time. We are going to retire it soon.
A fork of the project is listed on the now-decomissioned hardinfo GitHub project page - hardinfo2. @SoulHarsh007 has already built and added hardinfo2 to our repository.
Please consider replacing hardinfo with hardinfo2. You may do it like this:
sudo pacman -Syu hardinfo2
and accept the new replacement for the conflicting package.
