I noticed that too when beta testing the earlier builds. It has to do with us
(previously) setting value to unset variables ... which are now set.

For the Debian package I managed the change by moving the setting to
Renviron.site:

  ## edd Apr 2003  Allow local install in /usr/local, also add a directory for
  ##               Debian packaged CRAN packages, and finally the default dir
  ## edd Jul 2007  Now use R_LIBS_SITE, not R_LIBS
  ## edd Mar 2022  Now in Renviron.site reflecting R_LIBS_SITE
  R_LIBS_SITE="/usr/local/lib/R/site-library/:${R_LIBS_SITE}:/usr/lib/R/library'"

If you have those three lines you should be fine. I am (also on Uubuntu 20.04
which a binary from my PPA):

  # lsb_release -a 
  No LSB modules are available.
  Distributor ID: Ubuntu
  Description:    Ubuntu 20.04.4 LTS
  Release:        20.04
  Codename:       focal
  # Rscript --version
  Rscript (R) version 4.2.0 (2022-04-22)
  # Rscript -e '.libPaths()'
  [1] "/usr/local/lib/R/site-library" "/usr/lib/R/site-library"      
  [3] "/usr/lib/R/library"
