Hi everyone,

I'm trying to install Cisco Packet Tracer 8.2.2 on Linux Lite 7.0, which is based on Ubuntu 24.04. However, when I run the `.deb` installer, I get the following error:

packettracer depends on libgl1-mesa-glx; however: Package libgl1-mesa-glx is not installed.


I tried installing `mesa-utils` and other related packages, but it seems `libgl1-mesa-glx` is no longer available in the 24.04 repositories. I also searched for `.deb` packages online, but couldn't download them successfully from the Ubuntu mirrors.

Does anyone know a safe workaround for this? Maybe a replacement library or a PPA that brings this dependency back? I’d like to avoid downgrading my system or switching distros just for this.

Thanks in advance for any help!

Hi folks,

I have spent a couple of days fine tuning the Forums and I am really pleased with the results.

How do I know if my Windows PC has UEFI?

In Windows Search, type msinfo or msinfo32 and launch the desktop app named System Information. Look for the BIOS Mode item, and if the value for it is UEFI, then you have the UEFI firmware. If it says BIOS Mode Legacy, then that’s the firmware you’re running.

Secure Boot is supported, but unless you know exactly how to handle it, it is a P.I.T.A. at best so I am going to say...you must disable Secure Boot to enable stress free computing.

Some helpful snippets from the latest Help Manual:

I'm currently testing this on LL7.2 with the Xubuntu experimental PPA. Honestly all is quite promising. The link below displays some of my results.
