Fresh install Zorin OS 16 no Wifi

I am using the lite version. Just installed on DELL Latitude D630. When I enter the first command I get:

E: Unable to locate package build-essential
E: Package 'git' has no installation candidate
E: Package 'dkms' has no installation candidate

OS is not detecting any wifi.

These are because the system cannot connect to the net.

Can you relay the output of

sudo lshw -c network

Wifi Product and Vendor are the things we are looking for.

Here is the output:

During the installation, did you select to not install third party drivers?

I guess you and i are on the same page from 2018 :joy:, i wanted to ask the same question haha.

Which page?

I did select to install third party drivers but was not connected to internet. I will re-install with ethernet connected.

Well look at that... but no... We've just been down that road before here on this forum, too.

Already knew that the Intel Pro Wireless is secure in the kernel; just as well know that the RTL 8821CE is ever-broken...

The only other thing I have open is some Graphical Work.

Hi Aravisian,

I re-install the lite version and was able to execute these commands. But with no effect.

My latest output from sudo lshw -c network:

Is secure boot disabled ?

yes it is disabled. Should I enable it on installation?

sudo apt install --reinstall ca-certificates

Looks like the ethernet is no longer shown as unclaimed...
