我很少使用 Ubuntu Software 应用程序，但是当我今天打开它时，我看到它有一个通知说我的指纹扫描仪固件可以更新。

软件中心更新

但是，apt upgradeandsnap refresh命令输出一切都是最新的。我是否缺少系统上的第三个软件包来源？

在检查手册时do-release-upgrade，我发现它有一个--frontend参数可以与一个值一起传递给命令。但是，联机帮助页没有解释参数的确切作用，或者它的可用值是什么。

       -f FRONTEND, --frontend=FRONTEND
              Run the specified frontend

我的假设是它允许我们通过软件更新程序或命令行等特定应用程序。我可以找到更好的描述和该参数的可能值列表吗？

跑步sudo do-release-upgrade时，我收到一条消息说：

Canonical 不再支持 16 个已安装的软件包。您仍然可以获得社区的支持。

我知道我可能不应该担心，但我如何才能在开始升级之前获得这些软件包的列表？

以下是do-release-upgrade选择continue之前的完整输出：http: //paste.ubuntu.com/12990830/

为了方便起见，这是其中最重要的部分：

Calculating the changes

Do you want to start the upgrade? 


16 installed packages are no longer supported by Canonical. You can 
still get support from the community. 

61 packages are going to be removed. 204 new packages are going to be 
installed. 1617 packages are going to be upgraded. 

You have to download a total of 1,220 M. This download will take 
about 55 minutes with your connection. 

Installing the upgrade can take several hours. Once the download has 
finished, the process cannot be canceled.
