Today, upon rebooting after an update, Linux Lite informed me that there were no network devices available.
Rebooting into Linux 5.4 solved that problem.
Are there any known issues with Linux 5.8?
Not really sure where to put questions like this.
I probably should have put it in the Bugs forum?
Because it is a bug.
Windows works, of course, so it must be something related to kernels and drivers and services/daemons.
Would be interesting to see if this affects others, and not just me (which would be typical)
EDIT:
The device is a bog-standard Realtek RTL8111 PCI Express Gigabit Ethernet Controller, integrated into my motherboard. My machine is a stationary PC, no wifi, and relatively recent.
I don't mind booting into 5.4, but I hope this gets fixed in 5.8.
Here is the output of:
EDIT_AGAIN:
According to this topic https://askubuntu.com/questions/1291313/...26-generic there was some work done that could cause problems with devices.
And another topic also suggests installing the linux-generic package - https://askubuntu.com/questions/1307447/...untu-20-04 - but it is already installed, although I noticed that the package depends on Linux 5.4 and not 5.8. I am not sure if that's a problem.
I will run the lshw command on my failed login, but it says UNCLAIMED for the device:
I then went to reinstall the linux-modules package for 5.8.0-38, and it complained that the corresponding linux-headers package for 5.8.0-38 wasn't installed, so I installed that and reinstalled. But the network card is still unclaimed on 5.8.0-38.
I am now going to boot into Windows and get work done, but it would be nice to see an update soon so that I can enjoy Linux
EDIT with the solution :
I ran and the network device worked in 5.8.0-38 after a reboot, hurray! 
I have no idea if I had the modules-extra package installed, but it worked. (Or maybe threatening to boot into Windows worked? :p )
So, this is not a fault of my own, but a glitch in the update procedure. My Linux Lite installation is only a couple of months old, so I am not to blame for this.
I hope that this information will be useful for someone else experiencing the problem.

Too many projects; too much time
