what do i choose then?
Debian 9 or 10 package?

PureOS 9.0 (amber) is based on Debian 10 (buster). If you need to download non-free Debian packages, you can search for them and download them individually from here:

Or you can edit your /etc/apt/sources.list file and add this line:
deb buster non-free

Then update the package list:
sudo apt update

By the way, uname -a shows that buster and amber use the same kernel:
Linux XXXXX 4.19.0-5-amd64 #1 SMP Debian 4.19.37-5+deb10u1 (2019-07-19) x86_64 GNU/Linux

Hey there, you can look at

cat /etc/debian_version

Thanks all.
