有没有办法通过命令行检查存储库中的程序是否可用？

Question

当我发现一个有趣的程序时，我想在 ubuntu 中测试并安装它，我首先检查它是否在存储库中可用。为此，我使用软件中心。

但是是否有可能通过命令行即 apt 或 aptitude 来检查它？类似 apt get install 命令？

Answer 1

您可以使用这些命令中的任何一个，

apt-cache search <package_name>

aptitude search <package_name>

apt-cache policy <package_name>

sudo apt-get install <package_name> -s

输出：

karthick@Ubuntu-desktop:~$ sudo apt-get install sun-java6-jdk -s

Package sun-java6-jdk is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package sun-java6-jdk has no installation candidate
