Typo in Renviron.site in R 4.2.0 on Ubuntu?

Hi,

I installed R 4.2.0 on Ubuntu (from CRAN apt repository) and some
startup errors lead me to Renviron.site and it's last line:

R_LIBS_SITE="/usr/local/lib/R/site-library/:${R_LIBS_SITE}:/usr/lib/R/library'"

Note the unmatched single quote just before the closing double quote.
That's a typo, is it not?
