Can't install libdouble-conversion1 on Ubuntu-19.10

  • 772

When I tried to install Cisco packet tracer from deb file it gave the following error: 

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

Then I tried installing libdouble-conversion1 using command sudo apt-get install libdouble-conversion1 . It gives the following error

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. Download these packages first:

      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. packet tracer 7.3

    2. Open terminal and change directory to Downloads (where the downloaded packages exist)

    3. Make all the downloaded packages executable (chmod +x packagename)

    4. Copy /home/username/.config/mimeapps.list to /root/.config/

    5. Install libdouble-conversion1 and qt-at-spi packages (sudo dpkg -i packagename)

    6. Install libjpeg-turbo8 package. Here, you may find library conflict error. If so, remove the old one (sudo apt purge packagename). There will be some warning.Just type this command (sudo apt --fix-broken install). And then, remove again. Now, you can install libjpeg-turbo8 package again.

    7. Install libjpeg8 package.

    8. Finally, you can install Packet Tracer 7.3 package.\

    Good luck

  2. You can use packages from other versions:

    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

    And then, install Packet Tracer from terminal:

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

  3. After downloading packet tracer,I tried installing it with sudo dpkg -i PacketTracer_730_amd64.deb and got this:

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

    When i tried to install qt-at-spi I got this message

    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).

    Running sudo apt --fix-broken install fixed all my issues,packet tracer was installed.
