好的，我找到了。

Apt-cache policy <package name>将显示版本详细信息。

它还显示当前安装的版本以及可安装的版本。

例如，apt-cache策略hylafax+

apt policy <package>

在短

在通过apt-get或apt安装时使用-V选项。您可以创建别名apt="apt -V"，以避免每次都手动输入。

例子:

# apt -V install podman

此外，根据手册页:

apt-cache showpkg <package_name>

也可用于:

...display information about the packages listed on the command line. Remaining arguments are package names. The available versions and reverse dependencies of each package listed are listed, as well as forward dependencies for each version. Forward (normal) dependencies are those packages upon which the package in question depends; reverse dependencies are those packages that depend upon the package in question. Thus, forward dependencies must be satisfied for a package, but reverse dependencies need not be.
