Hello Andrew, Regarding https://bugs.launchpad.net/ubuntu/+source/ubuntu-release- upgrader/+bug/2027592, I personally experienced two different root causes for black screens during kernel updates:
1) apt is holding back linux-modules-nvidia-*-generic. This happened to me at least three times. See https://www.reddit.com/r/Ubuntu/comments/12efuxu/nvidia_drivers_regularly_borked_by_phased_updates/. 2) linux-modules-nvidia-535-6.2.0-25-generic does not exist. This happened to me with the combination of linux-generic 6.2.0-25 and nvidia-driver-535. See the discussion in this ticket. I also experienced a black screen during the update from nvidia-driver-525 to nvidia-driver-535. This was without a kernel update. See https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-535/+bug/2025640. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-restricted-modules in Ubuntu. https://bugs.launchpad.net/bugs/2027914 Title: missing nvidia kernel module for generic kernel (linux-objects- nvidia-535-6.2.0-25-generic) Status in linux-restricted-modules package in Ubuntu: Confirmed Bug description: For latest generic kernel for Ubuntu 23.04 there in no package of kernel module.
