Public bug reported: I noticed something odd when I went to do-release-upgrade my Plucky machine (ASUS ROG Zephyrus G15) to Questing.
Initially, it had the 570-open UDA drivers installed, but do-release- upgrade claimed it was going to remove them, and it did not list any nvidia-driver packages in the install list to replace them with. I realized this was suspicious and worked around it on that machine by running `sudo ubuntu-drivers install` first, which installed the 580 drivers, after which the `do-release-upgrade` worked normally. To identify whether this would have caused an issue had I not done that, I reproduced this behavior on a DGX B200. To start out, I freshly provisioned a headless Plucky install via MAAS. Then, I installed the 570 drivers initially on there via `sudo apt install nvidia- driver-570-open linux-modules-nvidia-570-open-generic-hwe-24.04`, `sudo apt update && sudo apt dist-upgrade`d, then rebooted. Then, I ran `sudo do-release-upgrade` to go from Plucky to questing normally. The remove/install lists showed the same as what I saw on my Zephyrus (570 marked for removal, no 580 drivers marked for install at that stage). However, I'm guessing that might have been expected, since this appeared to uninstall the 570 drivers, then began installing the 580 *dkms* drivers.[0] After reboot, most of questing is installed, but cloud-init-base seems to have failed and prevented some things from being fully configured. (ex: `sudo apt install cloud-init-base` yields this: Summary: Upgrading: 0, Installing: 0, Removing: 0, Not Upgrading: 0 2 not fully installed or removed.
