Ubuntu 22.04において、aptでインストールしていたCUDA 12.3がある状態で、最近出た12.4にアップグレードするためにapt -y update && apt -y upgradeしようとしたとき、以下のようなエラーが出た。
$ sudo apt -y install cuda-12-4 cuda-drivers
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
cuda-drivers is already the newest version (550.54.15-1).
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
cuda-12-4 : Depends: cuda-runtime-12-4 (>= 12.4.1) but it is not going to be installed
Depends: cuda-toolkit-12-4 (>= 12.4.1) but it is not going to be installed
Depends: cuda-demo-suite-12-4 (>= 12.4.127) but it is not going to be installed
cuda-drivers : Depends: cuda-drivers-550 (= 550.54.15-1) but it is not going to be installed
libnvidia-decode-545 : Depends: libnvidia-compute-545 (= 545.23.08-0ubuntu1) but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
ここでapt --fix-broken installを入力しても特に解決しなかった。
$ sudo apt --fix-broken install
The following packages were automatically installed and are no longer required:

これが悪さをしているらしい。
そんなとき、この一時ファイルに対してdpkg -i --force-overwriteコマンドを使うと事態が進展した。

この時点ではまだエラーが出ているが、この後もう一度apt --fix-broken installすると（なぜか）エラーが出なくなり色々修正が働いたようだ。
その後
$ nvidia-smi
Failed to initialize NVML: Driver/library version mismatch
NVML library version: 550.54
nvidiaドライバが更新されたみたいなのでnvidia-smiを使えるようにするために一度再起動した。その後apt -y update && apt -y upgradeをすることで無事最新のcuda-12-4がインストールされ、nvidia-smiも働いた。
