Community.db failed to download - How do I resolve this?

[Phemisters]

The solution is discussed in several places; you need to comment out or remove the community lines from /etc/pacman.conf and then run sudo pacman-mirrors -f

See this post for instance: Tried to to update my system and I get this error - #9 by jeanmarc

and here

Error 404: Failed to prepare transaction

change this: [community] SigLevel = PackageRequired Include = /etc/pacman.d/mirrorlist to this: #[community] #SigLevel = PackageRequired #Include = /etc/pacman.d/mirrorlist or just delete those three lines then run: sudo pacman-mirrors -f to refresh the list of mirrors
