Sure, one by one.
The third command generated many lines starting with ‘Error’
and this:
sudo pacman -Syvv
sudo pacman -Syyu
yes the command gives errors, but they should be ignored…

Any more tricks up your sleeve?
try this:
go to /etc/pacman.conf, and locate the following section:
SigLevel = Required DatabaseOptional
and change the SigLevel to:
SigLevel = Required DatabaseNever
and then run again these:
sudo rm -rf /etc/pacman.d/gnupg
sudo rm -R /root/.gnupg/
sudo rm -f /var/lib/pacman/sync/*
sudo pacman-key --init
sudo pacman-key --populate archlinux manjaro
sudo pacman -Sy gnupg archlinux-keyring manjaro-keyring
sudo pacman-key --refresh-keys
sudo pacman -Syyu
This took more time, pity, the result is the same.
I could paste the output, but it doesn’t give any new information.
Are we getting near a new installation?
