Coral board : cannot resolve warning

newbie just started figuring out the coral board. I'm following the guide link

once I got to the Update point, sudo apt-get update

I get the following warnings

and when i try upgrading, sudo apt-get upgrade nothing gets upgraded

is it ok to ignore? I tried some test code, and it seemed like it's running just fine. I wonder if it did not skip, it might have upgraded some of the packages??

currently, package installed related to tensorflow from pip list,

tensorboard-data-server      0.6.1
tensorboard-plugin-wit       1.8.1
tensorflow-estimator         2.11.0
tensorflow-io-gcs-filesystem 0.29.0
tflite-runtime               2.5.0.post1

searching through google i have not found an answer to solve this warning.

when checking the sources.list from /etc/apt

multistrap-bsp.list>>
deb [arch=arm64] https://mendel-linux.org/apt/eagle-bsp-enterprise eagle main
deb-src https://mendel-linux.org/apt/eagle-bsp-enterprise eagle main

multistrap-edgetpu.list>>>
deb [arch=arm64] https://packages.cloud.google.com/apt coral-edgetpu-stable main
deb-src https://packages.cloud.google.com/apt 
coral-edgetpu-stable main

Solution

I recently solved it. for anyone with the same problem,

change directory to /etc/apt/sources.list.d
inside you have list files starting with multistrap.
comment out the second line which starts with deb-src

it allowed me to update and upgrade.
