During Debian (buster) installation, I got a message telling me that the files iwlwifi-5000[1-5].ucode were needed. I first finished installing without the files.
Then, after reading this related page:
https://packages.debian.org/buster/all/firmware-iwlwifi/download
I have added the following line to the file /etc/apt/sources.list
deb http://ftp.debian.org/debian buster main non-free
but when running the command:
aptitude search iwlwifi
I don't get any result.
Did I forget something or did anything the wrong way?
A stupid mistake for those often using aptitude or apt. I had forgotten to run:
aptitude update
after modifying the file /etc/apt/sources.list
Hoping this will be useful to someone.
