Ta carte wifi:

Il faudrait essayer de désactiver ton secure boot.

Notre documentation : desactiver_secure_boot

comme dans le fil de ludo77 : https://forum.ubuntu-fr.org/viewtopic.p … #p21556943, en version 14.04 et avec une carte wifi BCM43142.

Merci pour ton retour.

Peux tu modifier ton titre en :
