无法在 10.10 中安装 Adob​​e Flash 插件

我从软件中心安装了 Adob​​e Flash 插件。安装花了很长时间，从未完成。

重新启动后，软件包被标记为已安装，但 Firefox 仍然说它缺少这个插件。我尝试从软件中心卸载它，但它只是说永远“删除”。

我能做些什么？

更新

$ sudo apt-get install flashplugin-installer
E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?

我猜这是因为它仍然被“删除”（尽管软件中心窗口已关闭）。

重启后：

$ sudo apt-get install flashplugin-installer
E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.
