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

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+

下面的方法可能效果不错:

aptitude versions ^hylafax+

多看天赋(8)

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

你也可以简单地做常规的apt-get更新，然后，按照手册，做:

apt-get -V升级

-V显示详细版本号

它将显示当前包与将以类似于下面的格式升级的包:

~# sudo apt-get -V upgrade

正如在其他地方发布的，这也是有效的:
