Conflicting files - Does anyone know how to fix this?

[olympus1112]

conflicting files: -plasma-desktop: /usr/bin/knetattach already exists in filesystem (owned by knetattach)

plasma-desktop: /usr/share/applications/org.kde.knetattach.desktop already exists in filesystem

pamac normally fixes those automatically …

There’s a same problem recently:

Error while updating system

When I try to run sudo pacman -Syu I receive the message: error: failed to commit transaction (conflicting files) plasma-desktop: /usr/bin/knetattach exists in filesystem (owned by knetattach) plasma-desktop: /usr/share/applications/org.kde.knetattach.desktop exists in filesystem (owned by knetattach) Errors occurred, no packages were upgraded. This is probably an normal problem, but I couldn’t solve it with the solutions that I found online I’m new to manjaro
