Bug description:
[Impact]
* If a system is using canonical livepatch, has it enabled, and
patches are applied, it could be confusing for a user to receive a
"system restart required" messages in the MOTD when logging in.
* Livepatch is available on LTS releases. Thus, the users can be
confused following a kernel update on 20.04.
* The upload prevents update-notifier and unattended-ugprades hooks from
adding "system restart"-related messages to motd when Livepatch is enabled.
Livepatch, when enabled, already contributes to the motd message so there is
no need to have duplicate (and sometimes contradictory) information.
[Test Plan]
* how to reproduce the bug:
1. Install and boot a 20.04 server VM
2. Make sure it runs a generic kernel (or another flavour that supports
Livepatch)
3. Enable Livepatch using the following command:
$ ua attach <token> # replace <token> by an actual contract token
4. Upgrade the kernel (if you are already running the latest available
kernel update, you can install a different flavour)
5. Upon logging in again, the motd will show ***System restart required***.
* other testing appropriate to perform before landing this update:
* Making sure that the patch has no impact when livepatch is not enabled.
* The motd should show ***System restart required*** after upgrading the
kernel if livepatch is not enabled.
[Where problems could occur]
* The change updates a hook script in /etc/kernel/postinst.d/.
Scripts in this directory are executing when upgrading / installing a
kernel. If somehow the script is broken, it can prevent dpkg for
succeeding when upgrading / installing the kernel.
* If the implementation is wrong, we might end up "losing" the
***System restart required*** message when livepatch is disabled
[Original bug description]
If a system is using canonical livepatch, has it enabled, and patches
are applied, it could be confusing for a user to receive a "system
restart required" messages in the MOTD when logging in.
That message, when present, is printed by 98-reboot-required which
essentially just cats /var/run/reboot-required to stdout. That file is
placed by packages that require a reboot so that they are properly
used in their updated versions. Examples that come to mind are libc
and the kernel.
There is a secondary file that can be created which says which
packages requested the reboot. That would be /var/run/reboot-
required.pkgs
Ideally that script should not print out the reboot required message
if a) livepatch is installed and enabled; b) the only trigger for the
reboot is a kernel update.
For (a), one can use the command "ubuntu-advantage is-livepatch-
enabled" and check $?. That is in the ubuntu-advantage-tools package.
