All of a sudden, compilation of pdf files from my knitr/markdown *.Rmd files are now failing with the obtuse error message:
tlmgr search --file --global "/xcolor.sty"
tlmgr.pl: Remote repository is newer than local (2018 < 2019)
Cross release updates are only supported with

! LaTeX Error: File `xcolor.sty' not found.
! Emergency stop.
The compliation of the knitr/markdown file into latex works fine. It is the tinytex compilation of the knit.md file into a pdf file that is failing. knitr and tinytex are both up-to-date.
This is sort of urgent. How can I fix this? Thanks for any help. Larry Hunsicker
