In cases like this just take the set of packages and pass them
directly to
'sudo apt-get install' ie
$ sudo apt-get install r-base r-base-core r-base-dev r-cran-rpart
r-recommended
which will show which packages this will install (as new), upgrade,
or
remove, if any. It still allows you to pack out if you so choose.
In this case it is probably 'just' a fortran or c++ library
transition. If
you are still running gutsy you are also now two Ubuntu releases
behind so
you may want to consider upgrading to hardy and/or intrepid.
By the way, this would have a good question for the r-sig-debian
list.

Hi,
I encountered similar problems:
apt-get install r-base-core
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
Since you only requested a single operation it is extremely likely
that
the package is simply not installable and a bug report against
that package should be filed.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
r-base-core: Depends: tcl8.5 (>= 8.5.0) but it is not installable
Depends: tk8.5 (>= 8.5.0) but it is not installable
E: Broken packages
/etc/apt/sources.list
deb http://mirror.optus.net/ubuntu/ gutsy-security main restricted
universe multiverse
deb-src http://mirror.optus.net/ubuntu/ gutsy-security restricted
main multiverse universe
deb http://mirror.optus.net/ubuntu/ gutsy universe main
deb-src http://mirror.optus.net/ubuntu/ gutsy universe main

deb http://security.ubuntu.com/ubuntu/ gutsy-security universe main
deb-src http://security.ubuntu.com/ubuntu/ gutsy-security universe
main
It seems that R2.8.0 for gutsy is built on a system with tcl8.5 and
tk8.5, which is not available in gutsy?
From the CRAN Ubuntu README:
>>>
Installation and compilation of R or some its packages may require
Ubuntu packages from the "backports" repositories. In particular, this
is the case for Tcl/Tk 8.5 on Gutsy and Hardy. Therefore, it is
suggested to activate the backports repositories with an entry like
deb http://<my.favorite.ubuntu.mirror>/ hardy-backports main
restricted universe
in your /etc/apt/sources.list file. See http://www.ubuntu.com/getubuntu/downloadmirrors
for the list of Ubuntu mirrors.

Best wishes,
Leon
