Not sure why that would be different, but I just tried it and got the same (essentially) error:

No, itās a different error. Similar, but different. As such, the problem lies with Arch ā as was the case already, but if even downgrading the keyring doesnāt work, then they had better get to work on getting their signatures sorted.
The problem is apparently caused by one or several Arch maintainers stepping down, and their signatures being revoked as a result.
Worth noting, for this to work, one has to have installed the ārightā arch keyring, which currently is the January version, and not the latest from February. So a downgrade with sudo pacman -Syuu might be needed.
Apparently the signature issue has been resolved in archlinux-keyring 20260131-1, itās just that the latest stable release of Manjaro provides an older version.

I guess we still have to wait for the next Manjaro stable update in the coming weeks for this to be resolved. I still think this should be mentioned in the notes above, as it is currently preventing an upgrade unless one is willing to downgrade the keyring or reduce the trust level.
Several recommended fixes have been presented, and are approved by the Manjaro Team. Therefore, the problem is fixable and there are no negative side-effects.
What recommended fix? You gave me one suggestion that didnāt work, told me the problem is on the Arch side, which means I canāt upgrade until the upgraded key-ring package filters into Manjaro Stable.
Something else - not recommended for regular use - is to use --overwrite or --noconfirm, but itās really better to wait a bit until the issue resolves itself.
