Title:
--no-oem option is broken
Status in ubuntu-drivers-common package in Ubuntu:
Confirmed
Bug description:
[Impact]
* ubuntu-drivers supports the --no-oem option, which is meant to filter-out
the OEM metapackages when running on certified hardware.
* When ubuntu-drivers is invoked with --no-oem as a global option (i.e.,
`ubuntu-drivers --no-oem list` or `ubuntu-drivers --no-oem install`, the script
crashes with the following exception:
NameError: name 'install_oem_meta' is not defined
* When ubuntu-drivers is invoked with --no-oem as a sub-option of
"install" (i.e., `ubuntu-drivers install --no-oem`), the script does
not crash but the option is silently ignored - resulting in an OEM
metapackage to be installed if we are running on certified hardware.
This defeats the purpose of the option.
* Today, the --no-oem option can be passed to ubuntu-drivers by ubiquity as a
suboption of `ubuntu-drivers install`. By default, the option is not passed to
ubuntu-drivers but the users can opt-in using preseeds. If they do, their
decision is essentially ignored since the OEM metapackage will still be
installed:
https://git.launchpad.net/ubiquity/tree/scripts/simple-plugins#n20
* As part of the 23.10 cycle, subiquity will start replacing the
functionality from ubiquity for OEM installs. At the moment, subiquity
relies on the version of ubuntu-drivers-common from the system being
installed. But going forward, we might have to ship ubuntu-drivers-
common in the subiquity snap. This means we will fetch the deb from
jammy-updates since subiquity is a core22-based snap.
[Test plan]
1. We will compare the result of the following commands with and without the
patch (both on certified and on un-certified hardware):
* ubuntu-drivers --no-oem list
-> crashes without the patch. Should not crash with the patch. The list
returned should not include the OEM metapackage.
* ubuntu-drivers --no-oem install
-> crashes without the patch. Should not crash with the patch. The list
of packages installed should not include the OEM metapackage.
* ubuntu-drivers install --no-oem
-> without the patch, the OEM metapackage gets installed on certified
hardware. With the patch, it should not.
2. We will ensure ubiquity stills manages to install ubuntu on
certified hardware. We will also ensure that the OEM metapackage does
not get installed when it should not.
[Where problems could occur]
* When used as a global option, --no-oem currently makes the script crash
unconditionally. Therefore, the change should be very low risk in that regard.
* When used as a suboption of "install", the --no-oem option currently gets
ignored silently. If people have been automating ubuntu deployment in one way
or another and have used --no-oem, they might be surprised to notice that fewer
packages get installed on their target system, after the option is fixed. This
is theoretically a good thing, but might require some adjustments on their end.
