Can't install Cisco Packet Tracer 8.2.2

  • 772

I am trying to install Cisco Packet Tracer on my computer, but no matter what it won't work. When trying to install the .deb file provided by Cisco it says that

Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Note, selecting 'packettracer' instead of './CiscoPacketTracer822_amd64_signed.deb'
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 packettracer : Depends: libgl1-mesa-glx but it is not installable
E: Unable to correct problems, you have held broken packages.

Trying to install libglq-mesa-glx gives the error

Package libgl1-mesa-glx 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 'libgl1-mesa-glx' has no installation candidate

Does anyone know what I need to do or where I can get the libglg-mesa-glx installer? also, what even is an installation candidate? Is there a way that I can install the windows version, if the linux one is broken? Sorry if this is a stupid question: I just installed linux two days ago, so I'm still getting used to it.

Versions:

Ubuntu: 24.04.1

GNOME: 46

kernel: Linux 6.8.0-45-generic

Packet tracer installer: 8.2.2

apt

    The error message in your question says packettracer : Depends: libgl1-mesa-glx but it is not installable in Ubuntu 24.04, but you can manually download the libgl1-mesa-glx package from Ubuntu 22.04 and install it in Ubuntu 24.04. Change directories using cd to the directory containing the CiscoPacketTracer822_amd64_signed.deb file that you downloaded and run the following commands.

    sudo apt update  
wget http://mirrors.kernel.org/ubuntu/pool/universe/m/mesa/libgl1-mesa-glx_22.0.1-1ubuntu2_amd64.deb 
sudo apt install ./libgl1-mesa-glx_22.0.1-1ubuntu2_amd64.deb ./CiscoPacketTracer822_amd64_signed.deb
