When running in strict snap confinement snap client binary is not
accessible. Additionally output format of snap client binary is
not guaranteed not to change. snapd REST API should be used instead.

It is possible that the platform integration glue may have already prepared a
summary of host key fingerprints at the state directory. If so, use it
otherwise, try to build the summary directly.

In strict snap confinement, sshd config or host keys are not accessible.
If strict confinement is detected, instead allow reuse of
the host keys fingerprints already prepared by invoking process.
Prepared fingerprints are stored in: /run/console-conf/host-fingerprints.txt

Since we set a project name centrally, it implies a specific path to the state
directory. Instead of hardcoding the same value directly again in the controller
code, use the application level state directory.

Make sure that console-conf related apps use the same value for project, which
results in using the same shared state directory.

'project' value is used to construct /run/<project> path
Other parts are already using 'console-conf', prefer this syntax.
In the future we might consider using SNAP_NAME, and this '_' are
not permitted as part of the snap name.

In preparation for running console-conf as a strictly confined snaps, review of
the existing code has shown that user's key fingerprints are not being used or
displayed anywhere. Since we would not be able to read those public keys anyway,
we may as well drop the code which attempts to device the key fingerprints.

Add version checks for cloud-init to know if we can read status in JSON
format or not. If so, use that for a superior answer to the legacy
format. Handle legacy code paths also.
Autoinstall related failures are more likely than not going to be
user caused, so we shouldn't immediately generate a crash report
for these types of failures. This should hopefully allow the user
to debug their autoinstall data much faster and reduce the number
of autoinstall-related bugs reported.
When setting up the logging in a strictly confined snap, use the 'root' group,
rather than 'adm'. This will not interfere with the sandbox's policy but also
does not result in providing wider access to the logs.

Adds a base exception type for Autoinstall related failures and a
specific implementation for autoinstall validation failures.
When a user passes incorrect autoinstall data, the installer will crash
with an AutoinstallValidationError exception. Failure messages are
currently in the form of:
"Malformed autoinstall in '<autoinstall_key>' section"
where <autoinstall_key> is the name of the top-level key a particular
controller is responsible (e.g., 'apt' and MirrorController).
The section reporting is a little crude in the validation
of the base schema done by SubiquityServer, which can't discern
between the 'interative-sessions' and 'version' keys, but for now
the scope is pretty limited and can be fixed up at a later time.
SubiquityServer is responsible for checking and loading the
interactive-sessions, so it should be responsible for validating
this section as well. Additionally add this to the autoinstall
schema in the docs.
_AsyncValidatedMixin has been merged into the parent UsernameEditor,
reluctantly. I like the concept of _AsyncValidatedMixin, but what's
happening here is that UsernameEditor has inherited from 3 classes, the
first of which is in urwid, and when the constructor /
super().__init__() status changed in urwid,
_AsyncValidatedMixin.__init__() stopped being called.
OK cool, so maybe we'll just manually run initializers in the case where
it matters. That's semi-better, but with old urwid we end up calling
_AsyncValidatedMixin.__init__() twice (once directly, once by the urwid
__init__ using super()).
Further workarounds could be employed but at the moment there is one
user of _AsyncValidatedMixin, so just merge it into UsernameEditor.
Instead of manually changing the autoinstall-schema reference,
use literalinclude to insert the autoinstall-schema.json file
from the root of the repository.
Provided autoinstall data is already validated against a specific
schema by the relevant controller, but these schemas themselves
are never validated against a meta schema to guarantee they are
valid JSON schemas. This patch adds unit tests for each controller,
as well as SubiquityServer, to validate their autoinstall schema
against the latest JSON meta schema draft (that is supported in
jsonschema). A particular draft validator can be used instead by
specifying meta schema in the schema definition.
The SSHModel contained a ssh_import_id member variable. According to the
comment, it was originally meant to store meta-data about a SSH key ;
and was supposed to allow showing some sort of info back in the SSH view
if the user decides to go back.
I suspect that this variable has been unused for a long time.
Furthermore, it can only hold information about a single SSH key and we
support multiple keys..
Let's get rid of it.

The /etc/lsb-release file currently on noble shows:
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=24.04
DISTRIB_CODENAME=noble
DISTRIB_DESCRIPTION="Ubuntu Noble Numbat (development branch)"
Therefore, the Ubuntu Pro pages get skipped. This makes testing on noble
difficult, so make an exception for noble now and we'll drop it once
it's marked LTS.
