I've got a couple of Debian systems that (for various reasons) are running "testing" or "sid". I recently did apt update && apt upgrade && aptitude search '~o' on these machines and found that a number of firmware packages are considered "obsolete", presumably because they are no longer in any of the repositories listed in sources.list.
So what do I need to add to my sources.list file to get them back now? Here's what I see: root@kmac:~# aptitude search '~o' i A firmware-amd-graphics - Binary firmware for AMD/ATI graphics chips i firmware-linux - Binary firmware for various drivers in the Linux kernel (metapackage) i A firmware-linux-nonfree - Binary firmware for various drivers in the Linux kernel (metapackage) i A firmware-misc-nonfree - Binary firmware for various drivers in the Linux kernel root@kmac:~# Any thoughts?
