Did you check the PPA supported cosmic? For security reasons alone checking what a PPA (a 3rd party software source, un-vetted by anyone but it's author) is good practice. That PPA was last touched in 2014! so support ended at trusty (14.04). Checking your 3rd party sources before adding is good security practice, let alone avoiding these errors. (ppa.launchpad.net/tualatrix/ppa/ubuntu/dists or what I saw when I opened the error message url in browser; before adding I look at PPA info page & who author is etc not here)
