Comment 42 for bug 1498059

One additional issue I missed before... I'm running this Xubuntu 14.04 in VirtualBox and have the guest packages installed. I use the recently added -lts-wily packages that are built against the Wily stack.

So, they're shown in the unsupported list:

$ hwe-support-status --show-all-unsupported | grep virtualbox
xserver-xorg-video-vesa-lts-wily virtualbox-guest-utils-lts-wily
virtualbox-guest-x11-lts-wily libwayland-egl1-mesa-lts-wily
xserver-xorg-video-savage-lts-wily virtualbox-guest-dkms-lts-wily

However, 'hwe-support-status --show-replacements' doesn't show -lts-xenial replacements for them.

You can check these packages in trusty-updates repo:
