sks is already the newest version (1.1.6+git20210302.c3ba6d5a-4+b2).
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 sks : Depends: db-util but it is not going to be installed
       Depends: db5.3-util but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

頑張った

apt --fix-broken install

しかし、これは役に立ちません。 VirtualBoxで最新のDebian 12イメージを実行しています。
