[Bug 2068030] [NEW] No drivers detected for TU104GL [T4G] card

[Joao Andre Simioni]

Public bug reported:

ubuntu-drivers is not returning any driver for g5g instances in AWS,
which use Tesla T4G cards:

# lspci -tv
-[:00]-+-00.0  Amazon.com, Inc. Device 0200
   +-01.0  Amazon.com, Inc. Device 8250

   +-05.0  Amazon.com, Inc. Elastic Network Adapter (ENA)
   \-1f.0  NVIDIA Corporation TU104GL [T4G]

I tried Noble and Jammy and both have the same behavior.

Manually installing the drivers works as expected (below is the output
in Jammy, as Noble is hitting
https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-
drivers-550-server/+bug/2062380 and freezes on module loading)

$ sudo nvidia-smi

[Bug 2061068] Re: debsums check failed

[Joao Andre Simioni]

Weichen,

this was a bug on the snapd package until version 2.61.2:

https://bugs.launchpad.net/ubuntu/+source/snapd/+bug/2057491

snapd is now updated to 2.61.3 and the issue is fixed. It's unrelated to
the changes you made.

I also tried to reproduce it in my environment with a fresh installation
and the issue didn't manifest, so I can confirm it's fixed.
