Debian 12에 SKS를 설치할 때 발생하는 문제

Debian 12에 SKS를 설치해야 하는데 다음 문제가 있습니다.

root@SRV1:~# apt update

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).

나는 노력했다

apt --fix-broken install

그러나 이것은 도움이 되지 않습니다. VirtualBox에서 최신 Debian 12 이미지를 실행하고 있습니다.
