ASUS ROG STRIX Z370-E Wireless not working (continued)

Question

I also have Asus ROG STRIX Z370-E GAMING motherboard with wireless card built in but running Ubuntu 18.04. I tried chili555 answer in post:

Asus Rog Strix Z370 EGAMING Wireless card not working

I do not have enough reputation to comment their, also my post is a bit long. When I ran make I was warned that

Makefile:976: "Cannot use CONFIG_STACK_VALIDATION=y, please install libelf-dev, libelf-devel or elfutils-libelf-devel"

So I tried this

sudo apt install libelf-dev
make clean
make

which seemed to work

..
..
Install rtlwifi SUCCESS

however the last line gave an error:

sudo modprobe rtl8822be
# modprobe: ERROR: could not insert 'rtl8822be': Exec format error

[edit]

@Jeremy31

$ modinfo rtl8823be | egrep -i 'file|vermagic'
modinfo: ERROR: Module rtl8823be not found.

$ modinfo 8823be | egrep -i 'file|vermagic'
modinfo: ERROR: Module 8823be not found.

$ modinfo rtl8822be | egrep -i 'file|vermagic'

Please edit the question to include results for modinfo rtl8823be | egrep -i 'file|vermagic' — Jeremy31, Aug 25 '18 at 11:08
Please edit your question to add the result of the terminal command: lspci -nnk | grep 0280 -A3 Welcome to Ask Ubuntu. — chili555, Aug 25 '18 at 13:16
It looks like one command doesn't find rtl8823be and the other command does, seems kinda odd. — Sam Murphy, Aug 25 '18 at 18:27
@Jeremy31 modinfo rtl8822be returned a filename and vermagic. All this is way beyond me, I am not sure how to interpret these results, please help. — Sam Murphy, Sep 05 '18 at 19:32
That looks good, what is result for mokutil --sb-state Normally the exec format error is the result of the kernel version in the file name not matching the vermagic. It might help if you looked at this question and provided results for the wireless script — Jeremy31, Sep 05 '18 at 21:40

Open Software & Updates from the start menu. Go to the Additional Drivers tab. There you will find the options to select your Wi-Fi and Graphics drivers. It will look like the image in the following link: https://ibb.co/gWd3yU

You may select the options I've selected. Then press Apply Changes. And hopefully, you are done.

"Additional Drivers" only installs driver for Broadcom devices. He has none. – chili555 Aug 26 '18 at 01:36
