I put the new 20.04 iso on a USB stick. I have booted and shut down from the USB stick several times. Each time, I get a new message when I’m shutting down. Last time, it was three lines starting with…
[ 97.605515] b43-phy0 ERROR: Firmware file “b43/ucode15.fw” not found.
I remember going through a b43 firmware problem on a version of Lubuntu several versions back. I believe this is a Broadcom Wi-Fi issue.
I have a Dell Inspiron 1545 laptop that came with Ubuntu pre-installed. The first time I upgraded the OS, I lost Wi-Fi and had to install some files. Then the second time I upgraded the OS, I was told in a forum that the Broadcom issues were fixed and the b43 installer didn’t need to be added in the future. (And indeed, on that OS installation, Lubuntu worked “out of the box”.)
I am wondering if I can go ahead an install Lubuntu 20.04…
I found my old USB dongle with the b43 zip file and command line instructions I used before for installing the files. I can do that exact thing again, but if anything has changed and I lose Wi-Fi, I am screwed.
So, did the previous Broadcom issue return? Or am I getting this message simply because I am booting from a USB (I have never done that before)?
If it sounds like I know what I’m talking about, I don’t. So please help.
