Você tem um kernel errado para o Ubuntu 15.04. Você precisa instalar o kernel correto primeiro.

Faça o download desses arquivos e copie-os para sua pasta pessoal.

linux- imagem

linux-image-extra

linux-firmware

linux- cabeçalhos

Em seguida, execute no terminal

sudo dpkg -i linux*.deb

Reinicie.

Se a sua conexão de rede for restaurada, execute

sudo apt-get install linux-generic

para instalar o meta-pacote. Isso ativará as atualizações do kernel.

Você tenta isso:

 sudo apt-get install linux-amd64-efi_ linux-efi
 sudo apt-get update
 sudo apt-get upgrade
 sudo apt-get install -f
 sudo apt-get install linux-efi*

e pode funcionar bem assim.
