Updates go wrong

updates go wrong
I got Manjaro mate installed on an imac i71, but updating for the first time goes wrong.
Here the error message,
Commit transaction failed.
conflicting files:
-plasma-desktop:/usr/bin/knetattach allready exists in filesystem(ownedby knetattach)
-plasma-desktop:/usr/share/applications/org.kde.knetattach.desktop allready exists in filesystem.
Who please help me.

That no longer exists. Remove it, then update.

What ISO did you use? Sounds like your base install is very out of date to begin with. Since you’ve barely begun, I recommend installing via the latest ISO via our official download page.
