Linux Mint, Debian 9, Ubuntu 16.04及更老版本:

短信息:

apt policy <package_name>

详细信息(与描述和视情况而定):

apt show <package_name>

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+

另外，apt-show-versions包(单独安装)解析关于已安装内容的dpkg信息，并告诉您包是否为最新的。

例子……

sudo apt-show-versions --regex chrome

输出:

google-chrome-stable/stable upgradeable from 32.0.1700.102-1 to 35.0.1916.114-1
xserver-xorg-video-openchrome/quantal-security uptodate 1:0.3.1-0ubuntu1.12.10.1

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.

例子:

apt-cache policy conky

conky:
  Installed: (none)
  Candidate: 1.10.3-1
  Version table:
     1.10.3-1 500

        500 http://us.archive.ubuntu.com/ubuntu yakkety/universe i386 Packages

在debian上:

apt list --upgradable

给出包含包、要升级的版本和包的实际版本的列表。

结果:
