@Ralf, after above error solved, just like to remind on few most important steps:
sudo apt update
sudo apt upgrade
wget http://ftp.us.debian.org/debian/pool/main/d/debian-archive-keyring/debian-archive-keyring_2021.1.1_all.deb
sudo dpkg -i debian-archive-keyring_2021.1.1_all.deb
wget http://ftp.us.debian.org/debian/pool/main/i/isenkram/isenkram-cli_0.48_all.deb
sudo dpkg -i isenkram-cli_0.48_all.deb
sudo isenkram-autoinstall-firmware
Your sources.list is messed up. Debian does not carry byzantium suite, so this is an invalid entry:
deb http://deb.debian.org/debian bullseye non-free
And it causes all the problems, notably 404 not found. No wonder, Debian does not have byzantium, only PureOS does.
Next, if you mix Debian bullseye with PureOS byzantium, you will run into problems related same packages in the two distribution being slightly different versions. This might not bite you, if you only install a single package from Debian, but then again, it depends on a particular package and its dependencies.
Last, doing apt-get upgrade will install the highest version of every package, picked indiscriminately from both Debian and PureOS, and that is sure to either give problems, or it will effectively discard PureOS and switch you over to Debian. (PureOS lags behind Debian a little bit, and thus uses older versions of packages.)
Dwaff,
All I need to do is, get the broadcom driver installed to run my wireless communication.
I have two systems running with PureOS 9 and that driver.
This time I was recommended to go with PureOS 10.
If you have a better way of getting this driver installed, please let me know.
For that, I would add debian bullseye non-free to the sources.list, do apt-get update, apt-get install , and then remove debian bullseye from the sources.list altogether.
Edit: And, importantly, I would never run apt-get upgrade in this short period of time, when sources.list contain debian bullsye entries. Only update, to get package list. Never upgrade.
What is the difference between:
‘sudo apt update’ and ‘sudo apt-get update’ ?
There’s no difference. Both are doing the same thing. Slightly different frontend is engaged, that’s all.
Will those two commands then get me the broadcom driver installed (after I get the bullseye path set right) ??
I’m reluctant to post an untested procedure, but nevertheless, here it is:
sudo su
/etc/apt/sources.list: deb http://deb.debian.org/debian bullseye non-free
apt-get update
apt-get install isenkram-cli
isenkram-autoinstall-firmware
/etc/apt/sources.list
isenkram-cli is part of main and therefore your proposal to use: apt-get install isenkram-cli might work well only if main, Debian 11 related one, added within sources.list, temporarily of course (certainly without executing apt-get upgrade, as you already noted, as not allowed under PureOS).
There is only one command that will do the magic, in particular. It is this one:
isenkram-autoinstall-firmware
For the purpose of “easy way” clarification, here below is attached partial output of:
sudo man isenkram-autoinstall-firmware
As there is no related feedback to your post, I rewrote your kind proposal up to my preferable liking (not because of I’m awaiting any relevant feedback either or thinking that what you already posted or I’m (re)posting here is everything needed, but might indeed do, at least in general under PureOS):
sudo su
/etc/apt/sources.list : deb https://ftp.debian.org/debian/ bullseye main non-free
apt-get update
apt-get install debian-archive-keyring
apt-get update
apt-get install firmware-linux-free
apt-get install firmware-misc-nonfree
apt-get install isenkram-cli
isenkram-autoinstall-firmware
/etc/apt/sources.list or mark it to something like this: ##deb https:// …, save/exit.Thanks, @Dwaff!
No worries yet, Quarnero. I just haven’t got around to it yet. I will surely let you all know how it turns out.
It looks like it was not able to find the driver it was looking for:

firmware-b43-installer package is in contrib repository (I wasn’t aware of this, sorry) so please add contrib to your sources.list, beside bullseye main and non-free.
Now you should proceed with (while rest is looking like very good job of yours):
sudo su
/etc/apt/sources.list : deb https://ftp.debian.org/debian/ bullseye main contrib non-free
apt-get update
apt-get install firmware-b43-installer
isenkram-autoinstall-firmware
exit to exit root./etc/apt/sources.list or mark it to something like this: ##deb https:// … , save/exit .Let us know if anything else needed.
I see also this. There is no byzantium in Debian. The corresponding entry in sources list needs to be corrected to point to pureos site, or removed.
The wifi is working now. Thank you so much Quarnero and Dwaff.
Hi guys,
Thanks for this awesome thread. I have the same issue with an old Macbook Pro and PureOS 10. My broadcom network controller is BCM43602 … (rev 01). I followed the steps as described until this point and I experience two issues.
First, regarding the sources.list:
I get the same error as Ralf, but I don’t have this source in my sources list:
E: The repository ‘http://deb.debian.org/debian byzantium Release’ does not have a Release file.
Nevertheless I was able to download and update the firmware installer
isenkram-cli is already the newest version (0.48)
firmware-b43-installer is already the newest version (1:019.7)
When I run isenkram-autoinstall-firmware It says
info: No new firmware package with requested firmware detected
Hence, when I open wifi settings it still says “no wifi adapter found”
Any ideas on how I can get my wifi adapter up and running?
Thanks,
D
Debian maintainers have another one ready for your particular Wi-Fi hardware (looks like it should help): https://wiki.debian.org/brcmfmac. Please proceed with here mentioned BCM43602 [non-free] link like this:
sudo su
apt-get purge firmware-b43-installer
apt clean
apt update
apt search firmware-brcm80211
apt-get install firmware-brcm80211
isenkram-autoinstall-firmware
apt-get autoclean
exit −− please close other open programs as well
sudo reboot
After your PureOS comes back please remove bullseye entry from /etc/apt/sources.list, connect your Wi-Fi … and execute: sudo time apt update to see if everything works.
EDIT (to explain): Actually: firmware-b43-installer was in contrib repo from … (therefore added) and in your case: firmware-brcm80211 package lies available within non-free repo from same …, yet to be consistent with main role of isenkram-autoinstall-firmware command please execute it before and without: apt-get install firmware-brcm80211 as isenkram-autoinstall-firmware command should pull this (or any other firmware) package by itself, I think. I’m just trying to avoid any sort of unnecessary confusion, make clear on why isenkram-autoinstall-firmware command is important by itself.
Thank you @Quarnero. I followed the step but it still says
Info: no new firmware package with requested firmware detected
How could I check which firmware is being used?
Update:
I also installed the b43legacy-installer (from debian 9 stretch as mentioned here) but with the same result: no new firmware package detected.
Update 2: Wifi now works
-> I used the command you edited out, rebooted and now I have a wifi adapter & wifi connection.
Thanks for your help @Quarnero
