PGP Could not be imported

[megavolt]

That scenario happens when the Manjaro packages are much older than on the mirror.

Unterstand that:

• You have pgp keys preinstalled on the iso.
• Manjaro is rolling and keys will change.
• Normally the pkgs archlinux-keyring and manjaro-keyring are signed with the previous keys.
• But in your situation: it just skips to the new pkgs, but it cannot be verified with your current key.

So generally:

1. Key is there.
2. It retrieves archlinux-keyring and manjaro-keyring, which contain the new keys, which are normally signed with the previous key.
3. After installing those, you can run a normal installation.

Now your situation:

1. Key is there.
2. It retrieves archlinux-keyring and manjaro-keyring, which contain the new keys, which are normally signed with the previous key, BUT you don’t have the previous key of that package.
3. Error…

Solution: Use the most current ISO or do a workaround like that:

# update mirrors
sudo pacman-mirrors -c Germany # or any other Country
sudo pacman-mirrors -f 5
# remove gnupg and re-init it
sudo rm -rv /etc/pacman.d/gnupg
sudo pacman-key --init
# remove pacman cache
sudo rm -Rf /var/cache/pacman/pkg/*
# download the newest packages which contains the gpg keys
sudo mkdir -pv $HOME/.cache/pkg/ 
# !!! Don't import keys here... so type "n" if asking. !!!
sudo pacman -Syw archlinux-keyring manjaro-keyring --cachedir $HOME/.cache/pkg/
# remove the signatures
sudo rm -f $HOME/.cache/pkg/*.sig
# Install the packages
sudo pacman -U $HOME/.cache/pkg/*.tar.zst
# clear the cache
sudo pacman -Sc
# Remove the downloaded packages again
sudo rm -Rf $HOME/.cache/pkg/
