Just to let folks know, the existing A.I. Support page has been discontinued.

We are working on a new system that will have a paid business model. With ad blocking, it is becoming increasingly difficult to fund the project - we must look to other means. Around $5 - $15 per month for unlimited usage, including coding and scripting LLM's.

It will be cheaper than ChatGPT and will be extremely fast with between 40 - 100 tokens p/second.

Just an FYI for folks - https://gallery.linuxliteos.com/

Should be much much faster and easy to use. Just need to upload the 7.4 images.

How do I correct this?
Thanks in advance!

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.

Could you please have a click around randomly and let me know if it feels snappier.  Thank you
