Confirmed in plain R using the same package built this morning from last
night's tarball from Denmark: Running update.packages() yields:
update.packages()
--- Please select a CRAN mirror for use in this session ---
Loading Tcl/Tk interface ... done
Error in read.dcf(pkgpath, fields = fields) :
Line starting 'unix; ...' is malformed!
OTOH I don't have a problem running my 'update.r' script (included in
littler as
/usr/share/doc/littler/examples/update.r) which just downloaded / upgraded
ten packages. It is equivalent to calling
repos <- "http://cran.r-project.org";
lib.loc <- "/usr/local/lib/R/site-library"
update.packages(repos=repos, ask=FALSE, lib.loc=lib.loc)
and that sequence also works in plain R. Could someone please dig into
update.packages() ?

Hmm, some of us are wary of running update.packages() in non-production
versions. Is the problem perhaps originating in getCRANmirors() or
chooseCRANmirror()?
(Neither of those read DCF files: my expectation is that this is
available.packages() reading a DCF file downloaded from a CRAN mirror.)
I do use update.packages() daily on pre-2.8.0 and I have not seen a
problem. (I keep a separate package installation for test versions.)
Can we please have some useful debugging info, e.g. the result of
traceback() and which CRAN mirror is being used? I suspect a problem with
downloading PACKAGES.gz resulting in a corrupt file (possibly because it
was corrupt on the mirror).
