I was hoping that the community could help me with a problem that has developed overnight on my Dell Precision 5630 laptop which is running Kubuntu 18.04 LTS. Everything had been running fine since Jan 2016 including when I shut down at around 11pm last night but when I booted up this morning at 8am I can no longer connect to any WiFi network. The network connections finds all of the networks and tries to connect but it just sits on the waiting for authentication. I've tried a couple of different networks as well as tethering to my phone but that is not working either. My phone connects to the wifi and I have removed the connection and entered in the password again to no avail.
Ethernet is working on the same network.
When I run a grep wlp I receive the output

Tailing /var/log/syslog whilst trying to connect shows

Here are the last two entries from the /var/log/apt/history.log file from when I last ran updates, though the wireless adapter was working fine for another 4-5 hours aferwards

I then try to connect and can see that the state is changing

But then it just times out.
The network adapter is a Intel Corporation Wireless-AC 9260
# lspci | grep -i network 3b:00.0 Network controller: Intel Corporation Wireless-AC 9260 (rev 29)
I'm a bit lost as to what could be the cause and what to try next.
If I look at the network services they are currently in this state
