When trying to knit in RStudio it writes a ligature in the tex file and cannot compile it

I'm working on a brand new install of Linux Mint (19.2), a brand new install of RStudio, and a brand new install of texlive.

When I try to knit an Rmarkdown file in RStudio I get the error 

! Package inputenc Error: Unicode char fi (U+FB01)
(inputenc)                not set up for use with LaTeX.

It seems to be producing a ligature for the characters "fi" and the LaTeX is not able to read this. However, I don't know how to make it stop producing this ligature. I tried looking for other solutions and it led me to installing the newest version of texlive-full and running the init-usertree. I tried then running install tlmgr inputenc and it returned an error. I looked up the error, the recommendation was to set texlive to an earlier version. Then I run it again and get

tlmgr install: package inputenc not present in repository.

Even if I chase this error down, it seems like I won't be solving my problem because this doesn't seem like it will fix the ligature issue. I saw one recommendation to change the LaTeX typeset so I switched it from pdflatex to xelatex but that caused no change.

The translation from Rmd to tex should not add an explicit fi ligature. Therefore, it is most likely that your Rmd file already contains the ligature, probably as a result of a previous copy & paste.
