从 Debian 11 Bullseye 升级到 Debian 12 Bookworm 后，我遇到了同样的问题。
# apt upgrade

Calculating upgrade... Done
The following packages have been kept back: sysv-rc-conf
在这种情况下，我使用 Aptitude 命令，它可以建议多个包冲突的解决方案。
# aptitude dist-upgrade
The following packages will be upgraded:
sysv-rc-conf{b}
1 packages upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
Need to get 21,6 kB of archives. After unpacking 1 024 B will be freed.
The following packages have unmet dependencies:
sysv-rc-conf : Depends: sysvinit-core but it is not going to be installed
The following actions will resolve these dependencies:
Keep the following packages at their current version:
1) sysv-rc-conf [0.99-7.1 (now)]
我没有接受保留包裹的建议解决方案。

The following actions will resolve these dependencies:
Remove the following packages:
1) sysv-rc-conf [0.99-7.1 (now)]
由于 Aptitude 提出了删除软件包的新解决方案，我接受了它。

The following packages will be REMOVED:
libcurses-ui-perl{u} sysv-rc-conf{a}
0 packages upgraded, 0 newly installed, 2 to remove and 0 not upgraded.
