I am re-asking this question on behalf of ECII who originally asked it on stackoverflow but which got shut down: http://stackoverflow.com/questions/22760473/automatic-update-to-3-1-0-beta-2014-03-28-r65330-on-ubuntu-12-04
The problem is as follows:
Ubuntu 12.04 machines are getting their installation of R automatically updated to 3.1.0 beta (2014-03-28 r65330), even without nightly repos, e.g. http://cran.at.r-project.org/bin/linux/ubuntu precise . This is a major problem for me as it means all the packages are now broken and I cannot install any new packages via install.packages. What is going on?
Why did that happen? R 3.1 is not even released? Is it a CRAN bug?
P.s. even the workarounds do not seem to work - e.g.
apt-cache showpkg r-base sudo apt-get install -f r-base-core=3.0.3-1precise0 - correct version
