Well its telling you the issue
That URL doesn't exist so you can't..
Can confirm looking at the URL http://ppa.launchpad.net/cairo-dock-team...ntu/dists/
There is not a Xenial option, which is Ubuntu 16.04 the base for LL3.8
The fix, remove the PPA and update again... (you'll find w/ PPA's this a norm)
Do you have other options, sure you can reach out to the Cairo Dev's to see if there options, or if they plan to update...
Some good info regarding PPA's: https://www.linuxliteos.com/manual/softw...type=0#ppa
