Hello everyone,
I just did a fresh install of Ubuntu 23.10 on my laptop, I was able to reinstall every single software excepted Cisco Packet Tracer. The error message by installing it from the official .deb package is the following one:
The following packages have unmet dependencies:
packettracer: depends: libgl1-mesa-glx but it is not installable
Of course I tried to install libgl1-mesa-glx from an old repository, but it didn't work. Has anyone managed to install it?
Thanks
Solved! Go to Solution.

Having the same issue. I attempted to apt-get install libgl1-mesa-glx, but I guess it isn't in the Ubuntu repository anymore.

This worked, thank you very much!
I'll also add that you should make sure to use gdebi when installing. For me, I was unable to accept the license agreement from the terminal, causing the download to freeze. You can install gdebi from Ubuntu repos in the terminal with the command "sudo apt-get install gdebi"

Thank you very much for your work! Solved the problem for me.
I just noticed the gdebi command can only install packages one by one, so I had to perform it again to install the second one.

I tried that way but didn't get any result. Someone can tell me how else can we do it?

If when installing a version of Packet Tracer, you see that it cannot be installed because it depends on the libgl1-mesa-glx package, which was a transitional package and is no longer available, you can install it manually.
Download the package manually, for example, from https://github.com/farhatizakaria/CiscoPacketTracer-Ubuntu_24.10/blob/main/libgl1-mesa-glx_23.0.4-0ubuntu1~22.04.1_amd64.deb
Then, in the terminal, install it manually with the command sudo dpkg -i, for example, sudo dpkg -i /home/(yourpcname)/Download/libgl1-mesa-glx_23.0.4-0ubuntu1~22.04.1_amd64.deb
Then, try installing the Packet Tracer version that was failing again. (If you see that you are missing more packages, simply continue installing those missing packages that are not on your computer)

1. Information at: https://github.com/farhatizakaria/CiscoPacketTracer-Ubuntu_24.10
3. Packet Tracer 9.0 does not require the libgl1-mesa-glx package; you can try installing it from https://www.netacad.com/resources/lab-downloads
