Glad to hear you are sorted out!

For what it is worth I

 - do not use private user libraries [1]
 - run update.packages() (over all of .libPaths()) daily to weekly

No issues.

[1] That is personal preference I reflected in the Debian package for your
actively suppressing them til I was told I can't / shouldn't. Now I just
suppress them at my end by setting the env vars to empty strings (and of
course ensure that /usr/local/lib/R/site-library is group-writeable by a
group I am in.)
