[R] Problem updating mgcv package

Hi All:

I tried to update the package mgcv from my current version 1.1-8 to mgcv version 1.2. Using the command update.packages("mgcv") to update mgcv failed in my computer and the returning message was:

"Error in old.packages(lib.loc=lib.loc, contriburl=contriburl, method=method, :no installed.packages for (?invalid) lib.loc=mgcv"

When I typed installed.packages(), I got the following information

libpath = "/usr/local/lib/R/site-library" for the installed package "mgcv".

My next error was when I typed
update.packages("mgcv",lib.loc="/usr/local/lib/R/site-library"). It returned the error message,

"error in download.file(url = paste(contriburl, "PACKAGES", sep="/"), :unsupported URL scheme"

What should I do to correctly update this package?

I use Debian Linux (MepisLinux), R version 2.0.1

Would greatly appreciate your advice.

TIA,
Arin Basu
