Je suis assez nouveau sous Arch et j'ai deux trois petits soucis, je vais donc créer des topics différents mais n'hésitez pas à me répondre partout

J'utilise actuellement yaourt et pacman (en fait principalement yaourt mais depuis quelques temps en faisant un yaourt -Syu je n'avais plus de mise à jour. Ce qui me semblait étrange). J'ai essayé de faire la mise à jour du système via pacman et voila l'output :
Code : Tout sélectionner
$ sudo pacman -Syu
