Issue with Glossa article

[cderv]

CI is failing because of Glossa

Locally I get

! Undefined control sequence.
<argument> \undefined 

and log is not so much helpful

l.74 \sffamily

Removing the \sffamily command does not help much.

Ok it works with

> tinytex::tlmgr("--version")
tlmgr --version
tlmgr revision 60693 (2021-10-04 04:24:25 +0200)
tlmgr using installation: C:/Users/chris/AppData/Roaming/TinyTeX
TeX Live (https://tug.org/texlive) version 2021

installed using tinytex::install_tinytex(version = "2021.10")

Also with latest tinytex::install_tinytex(version = "2021.11", repo = "https://ctan.mines-albi.fr/") using a special repo local to me.

Possibly something related to CTAN mirror issue. Using https://www.ctan.org/tex-archive gives me signature errors.

Doing a fresh installation while changing the repository works. I'll try something in CI to see.

[cderv]

Changing the repo does not help on CI.

Now it is working locally but can't make in work in our CI. Not sure why 🤔

For context, error is here since 14 days already as it was discovered in the PR https://github.com/rstudio/rticles/runs/4151469471?check_suite_focus=true

[stefanocoretta]

I'll have a look and get back to you!

FYI I just figured out the problem in #450.

@stefanocoretta thanks to @yihui the cause was found: it seems that microtype should not be installed in the TeX Live installation when glossa format needs to be rendered. A weird bug hard to debug.

Thank you @yihui !
