Quite possible. This is a fresh failure picking the 'US (MI)' mirror:

--- 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!
> traceback()
6: read.dcf(pkgpath, fields = fields)
5: .readPkgDesc(lib, fields)
4: installed.packages(lib.loc = lib.loc)
3: NROW(instPkgs)
2: old.packages(lib.loc = lib.loc, contriburl = contriburl, method = method,
available = available, checkBuilt = checkBuilt)
1: update.packages()

But if I then re-run chooseCRANmirror() and pick Austria, it still fails:

Error in read.dcf(pkgpath, fields = fields) :

yielding the same traceback.
