Wifi não está funcionando no Ubuntu 16.04

1

Eu tenho problemas com wifi no Ubuntu 16:04 64bit. Os problemas começaram após a atualização de 15.10 para 16.04. Eu tentei reinstalar os drivers de Wi-Fi, mas houve um erro:

sudo apt-get install --reinstall bcmwl-kernel-source :

Why why there is an error "DKMS: install completed. modprobe: ERROR: could not insert 'wl': Required key not available update-initramfs: deferring update (trigger activated) Processing triggers for initramfs-tools (0.122ubuntu8) ... update-initramfs: Generating /boot/initrd.img-4.4.0-22-generic"?

O que devo fazer para que meu wifi funcione novamente?
