[R-sig-Debian] Upgrading to R 2.5.1 on Ubuntu Feisty 64

[Christophe Bonenfant]

Hi there,

A new thread was started on the R list about problems to upgrade R to
version 2.5.1 and we were re-directed on this list. We are two with 
exactly the same problem and the same distribution (Ubuntu Feisty 64). 
We are unable to upgrade to R 2.5.1. The r-base-core package is version 
2.4.1 in Ubuntu repositories while all others r-cran related packages 
are upgraded to R 2.5.1 (r-base-dev,r-base...). This doesn't seem to be 
the case for the 32-bits version.

Do you have any tips to go through this? Thanks.

Christophe
