This bug was fixed in the package nvidia-graphics-drivers-450 -
450.80.02-0ubuntu0.20.04.2
---------------
nvidia-graphics-drivers-450 (450.80.02-0ubuntu0.20.04.2) focal; urgency=medium
* debian/templates/control.in:
- Add missing comma to fix FTBS.
nvidia-graphics-drivers-450 (450.80.02-0ubuntu0.20.04.1) focal;
urgency=medium
* New upstream release (LP: #1897910):
- Improvements:
o Added a new system-level interface using nvidia-capabilities
via /dev for Multi-Instance GPU (MIG) on NVIDIA A100.
For more information on these new device node capabilities,
refer to the MIG user guide.
o Added support for CUDA compatibility for CUDA 11.1, where CUDA
11.1 applications will work on supported GPUs when used with
drivers >= 450.80.00 on Linux. Refer to CUDA Compatibility for
more information.
- Fixed Issues:
o Various security issues were addressed. For additional details
on the med-high severity issues, review the NVIDIA Security
Bulletin 5075.
o Fixed an issue where, when NVLink training encounters a fatal
error, link training is still considered successful resulting
in broken nodes assigned to clients. An escape case in the
NVLink link state reporting caused the driver to report the
links as "Active" and functional even though the link had
received a fatal error. This fatal error does not allow
traffic to be sent over the link, and thus would cause P2P
apps to fail. This is a reporting issue, but not a
functionality issue. The lacking reporting case was
addressed, so the failing link state is properly reported.
o Fixed a software race condition that caused link training
failure (CUDA_ERROR_LAUNCH_FAILED). A race condition within
the driver polling code caused a false failure in some of
the link training steps. This causes the driver to not
continue link training even though training actually was
successful up to that point. The fix corrects these
sequences so that these false failures no longer happen.
* debian/templates/control:
- Provide cuda 11.0-1 and 11.0-1.

Bug description:
[Impact]
These releases provide both bug fixes and new features, and we would like to
make sure all of our users have access to these improvements.
See the changelog entry below for a full list of changes and bugs.
[Test Case]
The following development and SRU process was followed:
https://wiki.ubuntu.com/NVidiaUpdates
Certification test suite must pass on a range of hardware:
https://git.launchpad.net/plainbox-provider-sru/tree/units/sru.pxu
The QA team that executed the tests will be in charge of attaching the
artifacts and console output of the appropriate run to the bug. nVidia
maintainers team members will not mark ‘verification-done’ until this
has happened.
[Regression Potential]
In order to mitigate the regression potential, the results of the
aforementioned system level tests are attached to this bug.
