It has been brought to our attention that the latest version of the
metasploit package on the
community repository fails to upgrade due to an unresolvable dependency issue.
We recommend our users to run:
pacman -Syyu --ignore metasploit
to be able to keep their systems up to date.
We are not maintaining metasploit anymore as it was announced here, so please contact the upstream maintainer of the package about the issue
UPDATE (10/02/17): This issue has been resolved and users can update normally now.
