Installing igraph package R in ubuntu

Question

I use the following command to install the igraph package R in ubuntu: install.packages("igraph")

But I get an error message:

Warning: cannot access the index for the repository
http://ftp.iitm.ac.in/cran/src/contrib : cannot open the URL ' http://ftp.iitm.ac.in/cran/src/contrib/ PACKAGES 'Warning messages: package' igraph is not available (for version 3.3.2)

Can anyone address this issue where I am wrong about this ...

apt-get update     # now with new repos
