当我尝试从deb文件安装 Cisco 数据包跟踪器时，它给出了以下错误：

Unpacking packettracer (7.3.0) ...
dpkg: dependency problems prevent configuration of packettracer:
 packettracer depends on libdouble-conversion1; however:
  Package libdouble-conversion1 is not installed.
 packettracer depends on qt-at-spi; however:
  Package qt-at-spi is not installed.

dpkg: error processing package packettracer (--install):
 dependency problems - leaving unconfigured
Processing triggers for gnome-menus (3.32.0-1ubuntu1) ...
Processing triggers for desktop-file-utils (0.24-1ubuntu1) ...
Processing triggers for mime-support (3.63ubuntu1) ...
Processing triggers for shared-mime-info (1.10-1) ...
Errors were encountered while processing:
 packettracer

然后我尝试libdouble-conversion1使用命令安装sudo apt-get install libdouble-conversion1。它给出了以下错误

Package libdouble-conversion1 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 'libdouble-conversion1' has no installation candidate
dpkg dependencies apt cisco packet-analyzer

我几乎对 Ubuntu 中的编码一无所知。我目前正在双启动 ubuntu 16.04 LTS 和 Windows 10。一切都很好。但是今天发生了一个错误说

“找不到文件系统”

然后grub救援开始。在搜索了一段时间后，我发现了可以执行以下操作的解决方案：

ls
set prefix=(hd0,msdos5)/boot/grub
insmod normal
normal

我知道这ls是列出硬盘分区（如果我错了，请告诉我）。然后（在set prefix）我需要选择一个分区。选择 msdos5 时出现错误。经过一番尝试，我选择了 msdos6。然后它跑了。但问题是，从另一个解决这个问题的方法我写了这段代码：

set boot=(hd0,msdos6)

我想我搞砸了。可能，它涉及硬盘的哪个分区将要启动。现在，我的笔记本电脑在编写此代码后正在运行，每次打开笔记本电脑时，启动卡在开始时都会显示相同的错误，我需要每次编写代码我需要运行笔记本电脑的时间。我该如何解决这个问题？我可能还需要知道正在引导的分区 (msdos*) 并且我不知道如何找到它。
