Ubuntu – Unclaimed Network: install error 127 + 2 and execvp blacklist.sh permission denied with Intel Wireless 8260

14.04driversintel-wirelessnetworkingwireless

I think I have the same problem and have attempted the solution described here only to have a permission denied error. I have also tried the following but get Log output: 0: hci0: Bluetooth Soft blocked: no Hard blocked: no

Wireless LAN:

cornelis@Bob:~$ lspci -nnk | grep 0280 -A2
3d:00.0 Network controller [0280]: Intel Corporation Wireless 8260 [8086:24f3] (rev 3a)
    Subsystem: Intel Corporation Device [8086:1010]

More info: 2-in-1; 802.11a/b/gn/ac WLAN+Bluetooth 4.2; Intel Wireless-AC 8260; M.

Here's what I see in my terminal after trying the first linked solution:

Best Answer

You do not need those backports. Just upgrade the kernel and firmware by running

sudo apt-get install linux-generic-lts-wily
wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.156_all.deb
sudo dpkg -i linux-firmware_1.156_all.deb

and reboot.
