Pamac update cannot be updated from pacman

  1. sudo pacman -Syyu does not update
  2. pamac update or from GUI says that updated successfully but the versions does not change and the upgrade sign still exists.

I changed a mirror and updated successfully by sudo pacman -Syyu and pamac update sign has disappeared. Do the 2 apps get updates from different sources?

As far as I am aware, this isn’t the case. My guess is that somehow between one and another command issued, your mirrors received some updates. Other than that, a temporary lack of synchronisation in the database.

Why not? There should have been an error message clearly detailing the reason for the failure.

Because I need to display the pamac GUI
