RMarkdown generating pdf fmtutil-exe system error R version 4.0.0 (2020-04-24)

[Espressotoni]

Hello I am having problems generating a pdf with tinytex. It always prompt an error message

and shows in the console:

output file: test.knit.md

! Running the command ~\AppData\Roaming\TinyTeX\bin\win32\fmtutil-user.exe

! kpathsea: Running mktexfmt pdflatex.fmt

! The command name is ~\AppData\Roaming\TinyTeX\bin\win32\mktexfmt

Fehler: LaTeX failed to compile test.tex. See The R package tinytex - Helper Functions to Manage TinyTeX, and Compile LaTeX Documents - Yihui Xie | 谢益辉 for debugging tips. See test.log for more info.

I already tried reinstallation from CRAN and prebuild version.

Hello Espressotoni! Looks like it's not just you. In this topic we are discussing the same issue. Hopefully a solution will be found soon.

Hi Espressotoni - Yes, we're all experiencing the same issue. My last post, where I compared files from an older, working version, indicates not all files are installing on newer versions of TinyTeX, best I can tell, esp. the luatex.dll. Pls cross-post if you find a solution. Thx

Solution. Seems TeX Live is not working

[yihui]

The broken TeX Live has been flooding everywhere since yesterday: https://github.com/TeX-Live/installer/pull/13#issuecomment-628356626 Unfortunately there isn't much we can do about it at the moment. If you have an older working installation of TinyTeX, you can use that (or if someone else has a working version, you can copy it over), otherwise we can only wait for a day or two (or use a different LaTeX distribution).

Thanks for the info and your work!
