无法在 Ubuntu-19.10 上安装 libdouble-conversion1

当我尝试从deb文件安装 Cisco 数据包跟踪器时出现以下错误：

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 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使用命令进行安装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

  1. 首先下载这些软件包：

    1. libdouble-转换1 (http://ftp.br.debian.org/debian/pool/main/d/double-conversion/libdouble-conversion1_3.1.0-3_amd64.deb）
    2. qt-在-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. 数据包追踪器 7.3

  2. 打开终端并将目录更改为下载（下载的软件包所在的位置）

  3. 使所有下载的软件包均可执行（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。只需输入此命令（sudo apt --fix-broken install）。然后再次删除。现在，您可以再次安装 libjpeg-turbo8 包。

  7. 安装 libjpeg8 包。

  8. 最后，您可以安装 Packet Tracer 7.3 包。\

祝你好运

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>

答案3

下载数据包跟踪器后，我尝试安装它sudo dpkg -i PacketTracer_730_amd64.deb并得到以下结果：

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收到此消息

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，数据包跟踪器已安装。
