Ubuntu 18.04 with deprecated Hardware Enablement Stacks

  • 772

I have upgraded to 18.04 couple of weeks ago and today found out my currently installed HWE is deprecated.

hwe-support-status --show-all-unsupported output is:

linux-image-3.19.0-59-generic libwayland-egl1-mesa-lts-vivid 
linux-generic-lts-vivid xserver-xorg-video-all-lts-vivid 
linux-image-extra-3.19.0-58-generic xserver-xorg-input-all-lts-vivid 
xserver-xorg-lts-vivid linux-image-extra-3.19.0-59-generic 
linux-image-3.19.0-58-generic xserver-xorg-core-lts-vivid

and hwe-support-status --show-replacements output is:

linux-generic-lts-xenial libwayland-egl1-mesa-lts-xenial xserver-xorg-lts-xenial

But when I try to install these packages, I get:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package linux-generic-lts-xenial
E: Unable to locate package libwayland-egl1-mesa-lts-xenial

    It looks like you've got an HWE (hardware enablement) stack left over from 14.04, which has been deprecated for a long time now. It's common for upgrades to leave old packages installed. I would recommend uninstalling them:

    sudo apt remove linux-image-3.19.0-59-generic libwayland-egl1-mesa-lts-vivid linux-generic-lts-vivid xserver-xorg-video-all-lts-vivid linux-image-extra-3.19.0-58-generic xserver-xorg-input-all-lts-vivid xserver-xorg-lts-vivid linux-image-extra-3.19.0-59-generic linux-image-3.19.0-58-generic xserver-xorg-core-lts-vivid

    I'd also run these commands just to make sure you don't have any other 14.04 HWE packages installed:

    dpkg --get-selections | egrep "utopic|vivid|wily|xenial"
dpkg --get-selections | egrep "linux-.+-(3\.16|3\.19|4\.2|4\.4)"

    If you do, you can uninstall them with these commands:

    sudo apt purge `dpkg --get-selections | egrep "utopic|vivid|wily|xenial" | awk '{print $1}' | tr '\n' ' '`
sudo apt purge `dpkg --get-selections | egrep "linux-.+-(3\.16|3\.19|4\.2|4\.4)" | awk '{print $1}' | tr '\n' ' '`
