Hi,
I'm having some issues upgrading R. I'm using ubuntu linux 13.10, saucy and would like to upgrade R to the new version.I'm currently using 3.0.1
I've been following the instructions given in:1. http://stackoverflow.com/questions/10476713/how-to-upgrade-r-in-ubuntuand2. http://cran.r-project.org/bin/linux/ubuntu/

Here is exactly what i did, following mostly the stackoverflow description:
1) Added the cran mirror link to the sources list(I've actually tryed with 3 different mirrors just in case)sudo gedit /etc/apt/sources.listdeb http://cran.cnr.berkeley.edu/bin/linux/ubuntu/ saucy/
2) Getting the key step gpg --keyserver keyserver.ubuntu.com --recv-key E084DAB9gpg -a --export E084DAB9 | sudo apt-key add -
3) Run the updates/upgradessudo apt-get update && sudo apt-get upgrade
After a large list of succesful updates i get the following result in the terminal:

W: Failed to fetch http://cran.cnr.berkeley.edu/bin/linux/ubuntu/saucy/InRelease  
W: Failed to fetch http://cran.cnr.berkeley.edu/bin/linux/ubuntu/saucy/Release.gpg  Cannot initiate the connection to cran.cnr.berkeley.edu:80 (2607:f140:0:8000::201). - connect (101: Network is unreachable) [IP: 2607:f140:0:8000::201 80]
W: Some index files failed to download. They have been ignored, or old ones used instead.Reading package lists... DoneBuilding dependency tree       Reading state information... Done0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

I've done this a few times. At this point there are no more updates and the R error is isolated.
Is there a solution to this or should i just re-install R.
Thanks for your time,
Martin
