R Installation Problem - Ubuntu 15.04

General Q&A
1

Hello!

So I upgraded by OS from Ubuntu Precise (12.04) to Vivid (15.04) but I am unable to install R on this, after running it successfully on the older version.

I have tried various CRAN repositories in the sources.list file but none of them appear to be working. I have, however, installed other things using my command line so it definitely isn’t a network issue at my end.

I have attached a screenshot of the terminal. Please let me know where I’m going wrong.

This is what I have added in the sources.list file -

deb http://star-www.st-andrews.ac.uk/cran/bin/linux/ubuntu vivid/

This may be of interest for your problem http://askubuntu.com/a/75575

Have you tried different CRAN mirrors?

The error message seems to suggest your aptkey may also need updating

Solved the issue by installing the lone problematic deb file separately
from the mirrors’ link.

Also, RStudio is crashing each time I try to open it. Just installed. And
reinstalled a few times as well. Any idea why this is happening? For now, I
managed to make do with RStudio Server and access it through another
computer but I want to run RStudio as well.

I don’t know about RStudio. You should ask in their support forum https://support.rstudio.com/hc/en-us

RStudio Server is better and in fact, more suited to my use. Thanks anyway!
