Status in “linux” package in Ubuntu: Confirmed Bug description: The latest version of linux-firmware-nonfree does not install the firmware files to /lib/firmware as expected. In fact, if --reinstall is selected, the package actually removes previously installed firmware! Please see: http://ubuntuforums.org/showthread.php?t=2243562 Refer to posts #9 and following. On my own system, I did: sudo apt-get install --reinstall linux- firmware-nonfree. After it completes, I did: ls -al /lib/firmware/b43 and find: ls: cannot access /lib/firmware/b43: No such file or directory As this package installs required firmware for many ubiquitous Broadcom wireless devices, it is important that this bug be corrected soon.
