[R] Problem with updating packages

[Karl Schilling]

I am running R under Windows 11. recently updated R to the 4.6patchhed 
version. I then copied my packages from my previous version (4.5) to the 
library of 4.6. Then I updated all packages.

Since then, I see the following behavior:

Each time I run "update.packages(ask='graphics',checkBuilt=TRUE)" I am 
asked TWICE

"--- Please select a CRAN mirror for use in this session ---".

And, more embarrassingly, all my Cran and Bioconductor are said to 
require an update. That also happens when I run "update.packages", say, 
one hour after my last update.

And when I run "old.packages()", it seems that all my packages are 
identified as being old.

Any suggestions what might be going on?

Thank you so much in advance,

Karl Schilling
