I'm using R and RStudio in a new laptop and the installation is quite recent. I'm trying to knit a very simple PDF (so far just text in english and some data reading). Knitting to html works but pdf gives the following error message:
tlmgr update --all --self
tlmgr.pl: package repository http://linorg.usp.br/CTAN/systems/texlive/tlnet (not verified: gpg unavailable)
tlmgr.pl install: package already present: l3backend

Error: LaTeX failed to compile test_report.tex. See https://yihui.org/tinytex/r/#debugging for debugging tips. See test_report.log for more info.

I've installed tinytex with `tinytex::install_tinytex(), giving the following output (as far as I understand it worked?)
