Bug description:
This bug has some history that may be confusing from the comments.
Basically it started out as a Feature Freeze Exception, that's why we
had build logs, git logs and unit test runs attached.
Also, the "rename" that is mentioned elsewhere did not happen with
this package: the ubuntu-advantage name was kept, no new aliases were
added. This will happen in a later SRU, with a later version of the
package.

[IMPACT]
Most recent version of ubuntu-advantage-tool on github includes fips and livepatch enablement. The fips enablement will allow customers to easily install and configure Canonical's FIPS certified modules on xenial, whereas livepatch allows xenial and trusty customers to patch the running kernel without a reboot.
This SRU will cover both new features.
In addition to the new features themselves, a new "status" command was
added that will give a short summary about the available modules and
their status, at a glance.
Note: FIPS certified modules are only available for xenial. Livepatch
is supported on xenial and trusty. The tool will refuse to enable
either service on an unsupported ubuntu release.
Without this updated package, customers of those services have to
enable them manually by following a series of steps.
[FIPS DESCRIPTION]
When "ubuntu-advantage enable-fips <token>" is issued from commandline,
- configure the private PPA where the FIPS modules are located
- install the FIPS modules from this PPA to the local machine from where the script is run
- configure the bootloader to enable fips
Upon successful completion of these steps, the customer then gets a message stating to reboot
the machine to complete the fips enablement process.
Without the script, customers must perform the steps manually.
[LIVEPATCH DESCRIPTION]
Livepatch allows customers to apply kernel patches to a running system without rebooting it.
The current instructions live in http://ubuntu.com/livepatch and boil down to:
- install snapd if it's not installed already. On trusty this means a new kernel as well.
- install the canonical-livepatch snap
- obtain a livepatch token from Canonical
- run the enable command with the given token
The ubuntu-advantage-tools package simplifies this process by just
requesting the token and performing all the other steps on behalf of
the user. It also conveniently checks the running kernel and instructs
the user to reboot into a newer kernel if needed to finish the
installation (this is the case when running trusty).
[FIX]
Add fips and livepatch support to the ubuntu-adadvantage-tools
package. See debdiff below.
[LIVEPATCH TESTCASES]
TRUSTY
0. Install the new ubuntu-advantage-tools package to add livepatch support.
1. Collect status before enabling livepatch
type on commandline:
ubuntu-advantage status
expect:
livepatch: disabled
esm: disabled (not available)
fips: disabled (not available)
2. Enable livepatch
visit https://ubuntu.com/livepatch and obtain a token
type on commandline,
sudo ubuntu-advantage enable-livepatch <yourtoken>
You may be required to install a newer kernel. In that case, expect the
following output:
Installing missing dependency snapd... OK
Installing the canonical-livepatch snap.
This may take a few minutes depending on your bandwidth.
canonical-livepatch 7.24 from 'canonical' installed
Your currently running kernel (3.13.0-133-generic) is too old to
support snaps. Version 4.4.0 or higher is needed.
Please reboot your system into a supported kernel version
and run the following command one more time to complete the
installation:
sudo ubuntu-advantage enable-livepatch <yourtoken>
Once you reboot and re-run the specified command, expect:
Enabling Livepatch with the given token, stand by...
Successfully enabled device. Using machine-token: <sometoken>
Use "canonical-livepatch status" to verify current patch status.
3. Verify livepatch status
type on commandline,
ubuntu-advantage status
expect an output like the following,
livepatch: enabled

sudo ubuntu-advantage enable-livepatch foobar
expect,
Sorry, but Canonical Livepatch is not supported on zesty
[FIPS TESTCASES]

type on commandline,
sudo ubuntu-advantage enable-fips user:secret
expect,
Sorry, but Canonical FIPS 140-2 Modules is not supported on trusty

[REGRESSION POTENTIAL]
The current ubuntu-advantage-tools package in trusty, xenial and zesty is basically a NOOP because the only service it supports is ESM, which is only available for precise.
This update adds two new features to the package: FIPS (xenial only) and Livepatch (trusty and xenial), essentially making the package useful in trusty and xenial. For zesty there is no change, as none of these products are available for non-LTS releases.
In case of broken core functionality or specific broken features, note
that there is a manual instructions workaround if needed.
[OTHER INFO]
The way this package was made available in all the ubuntu releases where it is now was via a "pocket copy". That's why it has the exact same version in trusty, xenial and zesty. Currently artful has version 10 (a version 12 just missed the feature freeze), so in order for upgrades between releases to work, we adopted the backports versioning scheme, by appending the ubuntu release code with a tilda ("~") to the version.
Another point is that even though ubuntu-advantage-tools is "just" a shell script, it is unit tested with python3, and these tests (and lint runs) gate merges in the upstream github repository at github.com/CanonicalLtd/ubuntu-advantage-script/. The tests do not necessarily run on each ubuntu release because of the version of python that is available in each. A clean run without any changes can be obtained in xenial and higher. Trusty needs a newer python3 (3.5 at a minimum).
