xorg-core package does not provide xorg-video-abi version 24 ( it is version 25) under ubuntu 22 and later, makes it impossible to install cuda 10.2 or older

[Abram Wiebe]

Description: Ubuntu 22.10
Release: 22.10

xserver-xorg-core:
  Installed: 2:21.1.4-2ubuntu1
  Candidate: 2:21.1.4-2ubuntu1
  Version table:
 *** 2:21.1.4-2ubuntu1 500

Under Ubuntu 22, I was trying to make NVIDIA CUDA work, but I can't because the only compatible mix of CUDA and drivers results in a virtual dependency problem.

apparently the problem is the lack the xorg-video-abi-24 in the xserver-xorg-core package

as the grep command shows, only the video-abi-25 is provided in ubuntu 22 , but in order to install cuda 10.2 (or older), the version 24 is needed.

$ apt-cache show xserver-xorg-core | grep -E '(Package|Version|Provides)'
Package: xserver-xorg-core
Version: 2:21.1.3-2ubuntu2.5
Provides: xorg-input-abi-24, xorg-video-abi-25, xserver-xorg-video-modesetting
Package: xserver-xorg-core
Version: 2:21.1.3-2ubuntu2
Provides: xorg-input-abi-24, xorg-video-abi-25, xserver-xorg-video-modesetting

installing cuda 10.2 or older will give you this error:

 xserver-xorg-video-nvidia-510 : Depends: xorg-video-abi-24 but it is not installable or
                                          xorg-video-abi-23 but it is not installable or
                                          xorg-video-abi-20 but it is not installable or
                                          xorg-video-abi-19 but it is not installable or
                                          xorg-video-abi-18 but it is not installable or
                                          xorg-video-abi-15 but it is not installable or
                                          xorg-video-abi-14 but it is not installable or
                                          xorg-video-abi-13 but it is not installable or
                                          xorg-video-abi-12 but it is not installable or
                                          xorg-video-abi-11 but it is not installable or
                                          xorg-video-abi-10 but it is not installable or
                                          xorg-video-abi-8 but it is not installable or
                                          xorg-video-abi-6.0 but it is not installable

According to my research this package is the provider in focal
https://packages.ubuntu.com/focal/xorg-video-abi-24

Thank you for your bug report. Where do you get 'cuda-drivers-510' from?

$ apt-cache show xserver-xorg-core | grep -E '(Package|Version|Provides)'
Package: xserver-xorg-core
Version: 2:21.1.4-2ubuntu1
Provides: xorg-input-abi-24, xorg-video-abi-25, xserver-xorg-video-modesetting

So it seems the provide is correctly set on the xserver deb?

i can confirm this bug exists on 22.04.1 too,

$ apt-cache show xserver-xorg-core | grep -E '(Package|Version|Provides)'
Package: xserver-xorg-core
Version: 2:21.1.3-2ubuntu2.5
Provides: xorg-input-abi-24, xorg-video-abi-25, xserver-xorg-video-modesetting
Package: xserver-xorg-core
Version: 2:21.1.3-2ubuntu2
Provides: xorg-input-abi-24, xorg-video-abi-25, xserver-xorg-video-modesetting

this shows that the abi-24 provider exists, but upon installing cuda 10.2 (the latest version which supports my gpu) the error below comes up.

The following packages have unmet dependencies:
 xserver-xorg-video-nvidia-440 : Depends: xorg-video-abi-24 but it is not installable or
                                          xorg-video-abi-23 but it is not installable or
                                          xorg-video-abi-20 but it is not installable or
                                          xorg-video-abi-19 but it is not installable or
                                          xorg-video-abi-18 but it is not installable or
                                          xorg-video-abi-15 but it is not installable or
                                          xorg-video-abi-14 but it is not installable or
                                          xorg-video-abi-13 but it is not installable or
                                          xorg-video-abi-12 but it is not installable or
                                          xorg-video-abi-11 but it is not installable or
                                          xorg-video-abi-10 but it is not installable or
                                          xorg-video-abi-8 but it is not installable or
                                          xorg-video-abi-6.0 but it is not installable
i'm downgrading to 20.04 for now.
