When I tried to update, I get this errors: Update/upgrade fails though because of ca-certificates (64bit):
Try this from a terminal:
sudo pacman -Syu ca-certificates --force
If that doesn’t work then open dolphin as root and delete all ca-certificate dir’s under /var/lib/pacman/local/ and then run command above…
It works after deleting those files and reboot
/usr/share/ca-certificates/mozilla/Entrust.net_Secure_Server_CA.crt
/usr/share/ca-certificates/mozilla/GTE_CyberTrust_Global_Root.crt
/usr/share/ca-certificates/mozilla/RSA_Root_Certificate_1.crt
