update.packages(checkBuilt=TRUE) returns Error: invalid version specification NA in 2.9.0

Just tried a minute ago with the Austria mirror as you said, and I still
get the error.
Can you please tell us the result of
traceback() after you did that.

Are you sure you have no *old* base packages in the library you want to 
run update.packages() on?
Are you sure that all packages within your library are valid?
Do you have others than just the standard library?

Just a guess: We had an issues with malformed PACKAGES files in the
Windows repositories.

Maybe you are affected here.
Can you please try in 24 hours from now to do that again using the
mirror in Austria.

If the problem persists, please let me know.

Thank you,

I installed R-2.9.0 yesterday, and followed the instructions in the R for
Windows FAQ, 2.8 What's the best way to upgrade?  It reads "run
update.packages(checkBuilt=TRUE, ask=FALSE) in the new R and then delete
anything left of the old installation."  I did this but it returned an
error.  It's the checkBuilt=TRUE which causes it, though I don't know
why:
leaving it out or changing it to checkBuilt=FALSE do not return errors.

update.packages(checkBuilt=TRUE, ask=FALSE)
--- Please select a CRAN mirror for use in this session ---
Error: invalid version specification NA

update.packages(checkBuilt=TRUE)
Error: invalid version specification NA
