如何删除您不知道正确名称的包？

Question

我已经从http://download.opensuse.org/repositories/home:/Horst3180/xUbuntu_15.04/all/下载了 arc-theme-solid_1450051815.946cbf5_all.deb 文件并使用软件中心安装了它，但是当我决定卸载它没有出现在软件中心。我想通过终端删除它，但想不出要卸载的包的正确名称。这是与在软件中心外安装任何软件包相关的普遍问题。另外，要卸载的包的名称是否与 .deb 文件的名称相同？

Answer 1

您应该能够通过阅读 deb 文件来使用dpkg -I或dpkg-deb -I显示有关包的信息。从man dpkg

   dpkg-deb actions
          See  dpkg-deb(1)  for  more  information  about  the   following
          actions.
          .
          .
          .
          -I, --info archive [control-file...]
              Show information about a package.

例如

$ dpkg -I arc-theme-solid_1450051815.946cbf5_all.deb
 new debian package, version 2.0.
 size 286706 bytes: control archive=42665 bytes.
     421 bytes,    12 lines      control

所以在这种情况下，包名是 arc-theme-solid
