Install problem ubuntu 16.04(Solved)

[pote]

I installed the drivers as described and did some troubleshooting - removed, reinstalled again.
lspci lists the cards, but there is no result of dmesg | grep frontend:

00:1f.6 Ethernet controller: Intel Corporation Ethernet Connection (2) I219-V (rev 31)
02:00.0 Multimedia controller: TBS Technologies DVB-S2 4 Tuner PCIe Card
03:00.0 Multimedia controller: TBS Technologies DVB-S2 4 Tuner PCIe Card
04:00.0 USB controller: ASMedia Technology Inc. ASM1142 USB 3.1 Host Controller

When trying to load the driver manually I get "Required key not available"

root@P:~/drivers/tbs# modprobe -v tbs6909fe
insmod /lib/modules/4.4.0-28-generic/kernel/drivers/media/dvb/frontends/tbs6909fe.ko
modprobe: ERROR: could not insert 'tbs6909fe': Required key not available

I have installed the drivers on an Ubuntu server 16.04 with no problems.
If anyone could guide me in the right direction it would be highly appreciated.

disable secure boot in BIOS.

Thank you so much! That fixed it!

Some further research lead to additional info that might be useful to others moving to Ubuntu 16.04:

"
Since Ubuntu kernel 4.4.0-20 the EFI_SECURE_BOOT_SIG_ENFORCE kernel config has been enabled. That prevents from loading unsigned third party modules if UEFI Secure Boot is enabled.

Since Ubuntu kernel build 4.4.0-21.37 this can be fixed by running

sudo apt install mokutil
sudo mokutil --disable-validation

Alternatively you can disable SecureBoot in UEFI aka BIOS.
