Hello, I am having problems replying to the forum, not sure why. However, I found the solution. I will post it…
OK the *sig files in /var/lib/pacman/sync/ were damaged by my stupid Netgear WIFI extender! I could see the Netgear “mywifiext” URL in there.
I just deleted *sig and now Pacman works fine.
Seems to be SOLVED. Thanks.
