package r-cran-fcalendar 220.10063-1 failed to install/upgrade:

All these dapper r-cran packages:

r-cran-fcalendar 220.10063-1
r-cran-fmultivar 220.10063-1 (bug 248152)
r-cran-fextremes 220.10063-1 (bug 248154)
r-cran-quadprog 1.4.7-2 (bug 248155)
r-cran-fportfolio 220.10063-1 (bug 248156)
r-cran-fbasics 220.10063-1 (bug 248162)
r-cran-acepack 1.3.2.2-1

fail postrm with ".: 197: Can't open /usr/lib/R/etc/ldpaths"

This also causes the following packages to fail installation (since they depend on the hardy versions of some of the above packages):

r-cran-fseries (bug 248157)
r-cran-fimport (bug 248158)
r-cran-ftrading (bug 248159)
r-cran-fassets (bug 248160)

I suspect this is linked to the fact that since r-base-core (2.4.0~rc20060926-1), /usr/lib/R/etc/ldpaths has been moved to /etc/R/ldpaths and a symlink left in /usr/lib/R/etc/.
Everything goes well until r-base-core is unpacked when the failures start to happen. I do not fully understand why though, after unpacking the symlink should be in place and the postrm scripts for those packages should not fail.

There is a similar issue reported in the debian bts (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=400726) for another r-cran package but unfortunately no answer from the maintainer.

I'm subscribing Dirk to this bug, I'd like to know if he stumbled in anything similar already in Debian.

Looks like http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=410951#22 clarifies the problem as well as giving the solution.

For the time being, as a workaround solution, can you try to launch the upgrade again?
Alternatively, you can try from a terminal with any of these commands:

sudo dpkg --configure -a
sudo apt-get dist-upgrade
sudo aptitude dist-upgrade

Please let us know if this permits you to configure correctly your system.

MOTU-sru is subscribed to decide if this is sru-worthy.
We have 32 dapper packages which are potentially involved:

r-cran-abind
r-cran-acepack
r-cran-car
r-cran-cluster
r-cran-date
r-cran-design
r-cran-effects
r-cran-fbasics
r-cran-fcalendar
r-cran-fextremes
r-cran-fmultivar
r-cran-fportfolio
r-cran-gregmisc
r-cran-hdf5
r-cran-kernsmooth
r-cran-latticeextra
r-cran-lme4
r-cran-matrix
r-cran-misc3d
r-cran-multcomp
r-cran-mvtnorm
r-cran-nlme
r-cran-psy
r-cran-quadprog
r-cran-rgl
r-cran-rsprng
r-cran-sandwich
r-cran-snow
r-cran-statdataml
r-cran-strucchange
r-omegahat-ggobi
r-omegahat-rgtk

The ideal solution would be to implement a fix through hardy-update that would allow the installation to proceed without errors. This could be done either with a no-op postrm or moving the depends on r-base-core to a pre-depends.

However, the issue can easily be solved by the user by running the upgrade again (I tested this successfully on a dapper chroot).

Will this SRU involve 32 source packages? Does fix from Debian 410951 solve this issue?

Impossible to say. Actually may be best. Worst-case is 32, yes.

Maybe. You'll need to test -- we don't usually have upgrades skipping several
releases. Also note that I wasn't the maintainer for #410952.

Sorry: "Actually may be best to test." is what I meant to write.

After a quick discussion with Cesare on #ubuntu-motu, there isn't a easy way to determine which package are affected or not, nor a common test case to check a proposed update. I'd like to see more details before approving this SRU.
