Re: Problem with installation Debian 9

[Josh Blagden <jfblagden@gmail.com>]

Joel is mostly right. I would just like to make the addendum that many wireless cards require non-free firmware blobs, not all of them. Some of them have free drivers. If you want an easy way to find wireless cards which work either with free drivers or without any drivers, check out the FSF's list of "Repects Your Freedom" hardware. For a more direct route, and possibly a more up-to-date list, check out Technoetic's wireless cards: https://tehnoetic.com/adapters

I personally don't mind non-free drivers, but I know some folks do, which is why Debian no longer ships with non-free drivers and it's also the raison d'etre for the FSF's "Repects Your Freedom" list.

The most common problem with wireless cards is that they require non-free firmware blobs. These used to be packaged with the kernel but Debian has packaged them separately for the past couple of releases.

The easiest thing you can do is perform the install using a wired network which is much less likely to require non-free firmware. Once the install is complete be sure to install the firmware-linux-nonfree package before trying to use your wireless network. As the name suggests, it is located in the non-free repository which you will need to add to your sources.

If installing from a wired network is not an option, try the unoffical installer which includes the non-free firmware. It can be found here: https://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/9.2.1+nonfree/amd64/iso-cd/

Good luck!

Hello,

I am trying to install Debian 9 (debian-9.2.1-amd64.netinst.iso) using USB booting method.

My laptop is  a Samsung RV420 - Core i5 - 4GB RAM - 640GB HDD

The installer detect my two network card (ethernet and wireless). I use the wireless card.

I complete the ESSID and password for the wireless network. But (after complete the password) the installer give the error:

What could be the problem?
