Arch whole system upgrade problem

[Souranil21 chakraborty]

so i ran the whole system upgrade command after installation of some apps and arch install inside a virtual machine and this problem occured. i ran the command after restating the system a few times but it kept throwing this error.

Try regenerate archlinux-keyring

try reinstall archlinux-keyring or run 
 

pacman-key --populate archlinux
pacman-key --refresh-keys

Chances are you can simply update the keyring through pacman, the keyring itself is not protected by a pgp key otherwise any key update would prevent everybody from upgrading.

 

sudo pacman -S arch-keyring

 

Generally if there is a keyring update pacman will grab it first automatically before it does what you asked it to.

it's usually just included with your normal packages, it doesn't go out of it's way to always make sure its up to date before continuing. If you update regularly then you will probably just end up updating it before the old one expires. Once it expires however you need to explicitly install it.

Also, the package is subject to the same requirements as any other package. If it falls to far out of date, you can just manually repopulate it or skip the verification process.
