PureOS 9 Wifi issue not working

[saleem]

Installed latest ISO but wifi not detected firmware not found

Can I add debian repos ( and which ones to add ? Latest version of PureOS is debian testing ?? ) to get my wifi working?

There is a manual on Debian wiki here: https://wiki.debian.org/wl

[saleem]

Thanks I will check , but what version of debian PureOS 9 is based?

[mladen]

Current stable.

[Quarnero]

Just follow (as described within link above) what is written under # Debian 10 “Buster”.

[saleem]

Thanks I tried but I get error

apt-get install linux-image-$(uname -r|sed ‘s,[^-]-[^-]-,’) linux-headers-$(uname -r|sed ‘s,[^-]-[^-]-,’) broadcom-sta-dkms

Reading package lists… Done

E: Unable to locate package linux-image-lts
E: Unable to locate package linux-headers-lts

current kernel on PureOS is vmlinuz-4.19.0-5-amd64 which is lts so do I put this kernel name in this command?

[saleem]

A bit more probing gives me some more clue which kernel is needed here

apt-get install linux-image-$(uname -r)

Alternatively I tried another command and it seems to be getting packages required

apt-get install broadcom-sta-dkms

Do you want to continue? [Y/n]

[Quarnero]

I would change buster-backports main contrib non-free to buster main non-free as first and than try again with correct command:

$ sudo apt-get install linux-image-$(uname -r) linux-headers-$(uname -r) broadcom-sta-dkms

File you are mentioning is from boot directory but your kernel is linux-image-amd64.

[saleem]

How about I add buster repos i.e below to PureOS? Will that break PureOS? Or will the whole concept of PureOS?

deb http://deb.debian.org/debian buster main contrib non-free
deb http://deb.debian.org/debian buster-updates main contrib non-free
deb http://deb.debian.org/debian-security buster/updates main contrib non-free
deb http://deb.debian.org/debian buster-backports main contrib non-free

[Quarnero]

Right. Yes, partially, if you want to install this Wi-Fi driver. Mainly from buster you need non-free, just once (without buster, buster-updates, buster/updates) meaning PureOS repository continues to be in charge for everything else, important things.
EDIT: If you experience problems with the above driver, for BCM4313 I think (not being in need to test this) that the key word here is brcmsmac (link to another option, Debian based, of recommended Kernel driver mainline version for old chipsets).
Anyway; “Please note: at least BCM4313 is not fully supported. Some models appears to work (users reported success), but some don’t, and there’s no indication that this is going to change.”

Thanks , I am following these instructions.

How to add PureOS gpg key? it has stopped working for me. I tried with

$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 2B4A53F2B41CE072
Executing: /tmp/apt-key-gpghome.St8wq8G26d/gpg.1.sh --keyserver keyserver.ubuntu.com --recv-keys 2B4A53F2B41CE072
gpg: keyserver receive failed: Server indicated a failure

but does not work

[Quarnero]

Many years ago there were times that people wanted Firefox on Debian, so do I. This was (maybe) good reason to add Ubuntu repo to SourcesList but I don’t think that mixing Debian/PureOS and Ubuntu repos (or vice versa) is adequate approach nowadays (as big number of the .deb packages have different names, although they might look like they are the same, but they are not, etc.). Thinking broad is fine, but relying on one distro might make things consequent and consistent.

Updating Coreboot when running another distro?

But to answer your question, Purism does have this keyring posted on the Github Repo. Not sure how far it will get you or whether it is up to date.

purism/pureos-archive-keyring

pureos-archive-keyring - The PureOS archive signing key package

[saleem]

No no I was not trying to add Ubuntu repos I was trying to add PureOS gpg key back with that command

Thanks I will try adding back the missing key you mentioned.
