Core 16 Fresh Install Broadcom kernel taints

Everything works fine so far - just poking around in my fresh install of Core 16..... what's this about?? I selected 3rd party drivers on install, since I have Broadcom wifi :frowning_face: not familiar with kernel taints.

$ dmesg | grep wl
17.076301] wl: loading out-of-tree module taints kernel.
[ 17.076311] wl: module license 'MIXED/Proprietary' taints kernel.
[ 17.079753] wl: module verification failed: signature and/or required key missing - tainting kernel
[ 17.082574] wl 0000:02:00.0: enabling device (0100 -> 0102)

[ 17.474856] wl 0000:02:00.0 wlp2s0: renamed from wlan0

Have you checked your firmware?

sudo service fwupd start

sudo fwupdmgr refresh

sudo fwupdmgr update

Fresh install with updates installed during install

Again, everything works fine on wifi, just wondering about the errors. :nerd_face:

It can happen if using an unsigned kernel or unsigned modules with a signed kernel.
The signed kernel may be "tainted" by the unsigned one - it is a security warning that if anything is unstable or broken in an unsigned module, this can affect stable and non-broken elements of the signed module or kernel.

Now I know. I learned something today, so I can have a beer and go to bed!
Thanks @Aravisian, perfect!
