some libraries not updating on Ubuntu

I am running the open source
R version 4.3.1 (2023-06-16) -- "Beagle Scouts"
Copyright (C) 2023 The R Foundation for Statistical Computing
Platform: x86_64-pc-linux-gnu (64-bit)
on Pop!_OS 22.04 LTS

I run the following from bash:
~$ sudo R

Here are my library paths:

.libPaths()
[1] "/usr/local/lib/R/site-library" "/usr/lib/R/site-library"
[3] "/usr/lib/R/library"

I run in R

update.packages(ask=F, checkBuilt=T)
OR
update.packages(ask=F, checkBuilt=T, oldPkgs = old.packages())

Then, whether or not some packages are updated, I get a result like,

Warning: package 'data.table' in library '/usr/lib/R/site-library' will not be updated
Warning: package 'dygraphs' in library '/usr/lib/R/site-library' will not be updated
Warning: package 'R6' in library '/usr/lib/R/site-library' will not be updated
Warning: package 'rJava' in library '/usr/lib/R/site-library' will not be updated
Warning: package 'timeDate' in library '/usr/lib/R/site-library' will not be updated
Warning: package 'TTR' in library '/usr/lib/R/site-library' will not be updated
Warning: package 'boot' in library '/usr/lib/R/library' will not be updated
Warning: package 'nlme' in library '/usr/lib/R/library' will not be updated

What can I do?

Thanks in advance for the advice!

I'd check the version numbers of the installed packages. I usually assume I alreadby have the most recent version installed but I may be wrong.
