I have exactly the same problem as reported by Guido Hooiveld.
I had previously attributed my problem with an inappropriate way of
updating my packages when I updated from R 4.5 to 4.6. I then completely
reinstalled R4.6 and all packages, which "solved" the problem - at
least
when I run "update.packages2 the same day I reinstalled everything (see
my postings and related answers from May27-29.
Alas, the next day the problem was back again, and ALL my packages
updated the day before were now identified as outdated.
I have no idea about the background of this problem. But a cue may be
possibly come from the observation that when I use RStudio to check for
packages that need to be updated (RStudie >Tools > Check for Package
Updates ...), this does not happen.
