Public bug reported:

Texlive in disco seems to be still at TL 2018.  However, it seems to
contain updated packages wrt comic that also was at TL 2018. The
packages in the Texlive mix shipped on Disco do not play well together.
This makes it impossible to compile some latex (in fact lualatex)
documents as lualatex errors out.

Specifically, Disco includes luaotfloader (the lualatex font loader) at
version "2.96" dated 2019-02-14 which is newer than the version shipped
in Cosmic. However, Disco still includes microtype 2.7a (the same as
Cosmic). Unfortunately, documents using microtype make lualatex error
out with this combination breaking latex flows.

The issue cannot be easily solved, because the Texlive manager (tlmgr)
does not let you update individual packages on a system based on Texlive
2018 now that Texlive 2019 is out, so one cannot use tlmgr to upgrade
microtype to 2.7b that would work fine with the luaotf loader shipped
with Disco.

Other incompatibilities that I have not yet encountered may also exist.

I believe that the proper solution to this issue would be to provide
Texlive 2019 for Disco.
