Fix JSS template by pinning the version of latexrelease package

[cderv]

Same fix as in 36f461d by pining the latexrelease package to older version (https://topanswers.xyz/tex?q=1416)

This should close #329 and fix the travis build #335 (comment)

let's see what travis think of that

So the fix indeed work for the branch : https://travis-ci.org/github/rstudio/rticles/builds/736422869

That is good to know we can pin some packages waiting for fixes upstream. I think doing that is enough and we don't need to pin the TinyTeX binary version. What do you think ?

I guess the other workflow will suceed, it is just long to run

Okay, I'll revert 1054e2b and merge this one. We should also notify JSS editors about this.

Do you have a specific contact or should we write to https://www.jstatsoft.org/about/contact ?

[cderv]

And maybe we need to cache again... 😞
We still get the "no output timeout" from travis, and builds are taking ~30min each...

Other idea: maybe we should build a binary specific from rticles testing ?

Just write to that email.

Let's try to figure out which packages are necessary (calculate the setdiff() for tinytex::tl_pkgs() before and after testing rticles, based on a fresh install of TinyTeX), and tlmgr install them in the before_install step.

[cderv]

OK I'll do that ! Thanks !

We really need a way to install packages in TeX Live like the mechanism of R's .libPaths(). I searched and tried a few weeks ago, but didn't figure it out. If that is possible, we only need to cache a package directory instead of the whole TinyTeX installation. I'll ask TeX Live developers later.

[cderv]

Oh yes that would be great. I have thought about it but I did not look into that yet as you said you would. That would solve issue with CI and latex dependencies for sure.

I've asked them and unfortunately the answer is no, but one of them said this was an interesting idea.

[cderv]

Oh too bad ! Thanks for asking. That prevent me for spending some time on this question. Glad they find that interesting ! We may see that appear one day then. For now, we will do without.
