So interpreting that site, added line:
deb http://r.meteo.uni.wroc.pl/bin/linux/ubuntu oneiric universe
to /etc/apt/sources.list and ran
(From experimentation I had to add the "universe" or "main" at the end to avoid parse error in the repositories list, preventing apt or synaptic from updating at all).
However the problem persists:
W: Failed to fetch http://r.meteo.uni.wroc.pl/bin/linux/ubuntu/dists/oneiric/main/binary-i386/Packages 404 Not Found
I enter that URL in a browser and clearly see that path is not there. However this is: http://r.meteo.uni.wroc.pl/bin/linux/ubuntu/oneiric/ (under which the Packages file actually lies, etc.)
Tried other mirrors, same problem.
The version of R available initially prevents me from installing updated packages, eg.:
> install.packages("PerformanceAnalytics") Installing package(s) into ‘/usr/local/lib/R/site-library’ (as ‘lib’ is unspecified) Warning message: In getDependencies(pkgs, dependencies, available, lib) : package ‘PerformanceAnalytics’ is not available (for R version 2.13.1)
Where I am going wrong?
