I followed steps to intall pynq in kria based on : GitHub - Xilinx/Kria-PYNQ: PYNQ support and examples for Kria SOMs
Initially, I started installation with the command:
git clone GitHub - Xilinx/Kria-PYNQ: PYNQ support and examples for Kria SOMs
cd Kria-PYNQ/
sudo bash install.sh -b { KV260 | KR260 | KD240 }
The first try the installation stopped because the “unattended-upgrade”.
When I restarted the installation with: sudo bash install.sh -b KR260,
then I get the following error:
/home/ubuntu/Documents/Kria-PYNQ
Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)).

Hi @Santiago_sanchez_ace

What image are you using? 22.04 or 24.04?

Are you able to install any other packages (either through pip or apt)?

Hi,

I am using 22.04.
I have three kria KR260. In two of them where I try to install the pynq the system shows the apt-key deprecated. I have been playing with both of them adding modules and later I try to install the pynq.
on the first two board I have been installing sudo apt modules, before to installing pynq i run sudo apt update and upgrade.

I have a third one, where I installed 22.04 clean (non installations of any other module) and I did not install anything else than the new BOOT firmware with sudo xmutil.

I got the same issue with the apt-key.

The point is that I try to use ubuntu 22.04 as it is the one that has more tools developed for kria kr260.

I have not tested the 24.04 installation.

Should I try to go for ubuntu 24.04?
