Problem setting up RubikPi 3

Canonical Ubuntu Ubuntu OS issues
1

Hi. I’m following the setup guide (here). Everything works up to the point of installing the PPA packages. I get the following output:

image
image598×206 29.2 KB

Also, the following output from uname -a is different from the one in the guide:

Linux ubuntu 6.8.0-1054-qcom #54oem2-Ubuntu SMP PREEMPT_DYNAMIC Mon Sep  8 12:15:35 UTC 2025 aarch64 aarch64 aarch64 GNU/Linux

Any idea what I might be doing wrong?

I’m not sure why you’re having this issue.
is your internet working on rubik pi 3?

Anyway, I recommend you to flash the image by using the launcher:

After that you should have newer system, and I guess it’s easier to start from that.
Let me know how it goes.

Thanks for your reply. Ping to external sites works, so the board is connected to the internet. I’ll try reflashing.

Re-flashing my board fixed the problem. There were a couple of issues I had to navigate, though:

  1. The QualcommLauncher kept generating an error setting up WiFi. So I had to quit the launcher prematurely and manually set WiFi through the debug terminal.
  2. When I continued with the setup procedure and entered:
sudo apt upgrade -y

It generated a number of errors. I tried:

sudo apt update

Then re-tried the upgrade and everything worked. After that, the install_ppa_pkgs.sh script finally worked!

Checking the Linux version, I get:

uname -a
Linux ubuntu 6.8.0-1056-qcom #57-Ubuntu SMP PREEMPT_DYNAMIC Tue Oct 21 15:36:21 UTC 2025 aarch64 aarch64 aarch64 GNU/Linux

Now, on to the next step!

Okay, thank you for your response.
