Comment 0 for bug 1523125

Recently, after upgrading a machine from 12.04 to 14.04 I noticed that neither keyboard nor network would work, making it rather hard to resolve the situation.

Upon further investigation, it turned out that this was because the linux-image-extra package was missing, and that 14.04 has some rather critical kernel modules, such as usbhid (keyboard and mouse) and r8169 (my network card).

Please make sure in the future that the basic necessities to interact with a system are in linux-image-generic, rather than extra.

root@hitchhiker:~# lsb_release -rd
Description: Ubuntu 14.04.3 LTS
Release: 14.04
root@hitchhiker:~# apt-cache policy linux-image-generic
linux-image-generic:
  Installed: 3.13.0.71.77
  Candidate: 3.13.0.71.77
  Version table:

What I expected to happen:
- After an upgrade, I expect the computer to react when I enter keys, move the mouse, or attempt to connect to it over the network

What happened instead
- the system was completely unreactive, and needed a boot from a live CD to revive it again
