无法在 Ubuntu-19.10 上安装 libdouble-conversion1

  • 772

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

    1. 首先下载这些包：

      1. libdouble-conversion1 ( http://ftp.br.debian.org/debian/pool/main/d/double-conversion/libdouble-conversion1_3.1.0-3_amd64.deb )
      2. qt-at-spi ( http://ftp.br.debian.org/debian/pool/main/q/qt-at-spi/qt-at-spi_0.4.0-9_amd64.deb )
      3. libjpeg-turbo8（http://archive.ubuntu.com/ubuntu/pool/main/libj/libjpeg-turbo/libjpeg-turbo8_2.0.3-0ubuntu1_amd64.deb）
      4. libjpeg8（http://archive.ubuntu.com/ubuntu/pool/main/libj/libjpeg8-empty/libjpeg8_8c-2ubuntu8_amd64.deb）
      5. 数据包跟踪器 7.3

    2. 打开终端并将目录更改为下载（下载的包所在的位置）

    3. 使所有下载的包可执行（chmod +x packagename）

    4. 复制/home/username/.config/mimeapps.list到/root/.config/

    5. 安装 libdouble-conversion1 和 qt-at-spi 包 ( sudo dpkg -i packagename)

    6. 安装 libjpeg-turbo8 包。在这里，您可能会发现库冲突错误。如果是这样，请删除旧的 ( sudo apt purge packagename)。会有一些警告。只需键入此命令 ( sudo apt --fix-broken install)。然后，再次删除。现在，您可以再次安装 libjpeg-turbo8 软件包。

    7. 安装 libjpeg8 包。

    8. 最后，您可以安装 Packet Tracer 7.3 软件包。\

    祝你好运

  2. 您可以使用其他版本的软件包：

    wget http://mirrors.kernel.org/ubuntu/pool/main/d/double-conversion/libdouble-conversion1_2.0.1-4ubuntu1_amd64.deb
sudo apt install ./libdouble-conversion1_2.0.1-4ubuntu1_amd64.deb
wget http://mirrors.kernel.org/ubuntu/pool/main/q/qt-at-spi/qt-at-spi_0.4.0-3_amd64.deb
sudo apt install ./qt-at-spi_0.4.0-3_amd64.deb

    然后，从终端安装 Packet Tracer：

    sudo apt-get install <absolute/path/to/your/package>

  3. 下载数据包跟踪器后，我尝试安装它sudo dpkg -i PacketTracer_730_amd64.deb并得到了这个：

    dpkg: dependency problems prevent configuration of packettracer:
 packettracer depends on qt-at-spi; however:
  Package qt-at-spi is not installed.

    当我尝试安装时，qt-at-spi我收到了这条消息

    Reading package lists... Done
Building dependency tree       
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 qt-at-spi : Depends: libqt4-dbus (>= 4:4.8.0) but it is not going to be installed
             Depends: libqtcore4 (>= 4:4.8~) but it is not going to be installed
             Depends: libqtgui4 (>= 4:4.8~) but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

    运行sudo apt --fix-broken install解决了我的所有问题，安装了数据包跟踪器。
