Arc driver installation failed on Ubuntu 22.04.5 LTS

[ChrisMa]

Hello,

I followed the driver installation instructions (https://dgpu-docs.intel.com/driver/client/overview.html) to install Arc770 driver on Ubuntu 22.04.5 LTS, but throw below error and thus I am not able to successfully execute apt update due to invalid release file.

wget -qO - https://repositories.intel.com/gpu/intel-graphics.key | \
sudo gpg --dearmor --output /usr/share/keyrings/intel-graphics.gpg

gpg: no valid OpenPGP data found.

Linux kernel is 5.15.0-119-generic, any workaround to tackle this issue?

Thanks and best,

Chris

Hello ChrisMa,

Thank you for posting in Intel community Forum.

I will do further research on this matter and post the response on this thread once it is available.

Thank you very much for your patience and understanding!

If you have questions, please let us know. Thank you.

Hi Michael,

Thanks for the reply. Recently I'm aware it could be the unsynchronized system time issue which leads to SSL check failure (see below screenshots). I'm asking for internal team to look into it. And I will let you know in case of any findings.

Best,

Chris

Hi ChrisMa,

Thank you for sharing the additional information regarding the issue. I've tried to simulate the issue that you've encountered by installing the latest available copy of Ubuntu 22.04.5. Based on my checks, the default version comes with kernel version: 6.8.0-49-generic pre-installed.

Following the instructions from https://dgpu-docs.intel.com/driver/client/overview.html

I was able to install the Arc Graphics driver for an Intel A770 graphics driver with no major issues. Since you're checking internally, I'll move our discussion internally as well.

Hi Ernesto,

Thanks for the updates.

Based on your findings I'm certain this issue is due to other reasons e.g. unsynchronized system time instead of driver issues.

So let me follow up the internally raised case and I think it's fine to close this ticket.

Much appreciated for looking into this.

Best,

Chris

Hi Ernesto,

Unfortunately I'm still facing this issue although the system time is synchronized. Most probably it's a PUBLIC KEY not signed issue.

So, could you help look into it again, thanks!
