This is a not too old R-devel on Linux, it already fails in R 3.4.4, and on
macOS as well.
The tar file seems valid, external tar can untar it, so maybe an untar()
bug.
setwd(tempdir())
dir.create("pkg")
cat("foobar\n", file = file.path("pkg", "NAMESPACE"))
cat("this: that\n", file = file.path("pkg", "DESCRIPTION"))
tar("pkg_1.0.tar.gz", "pkg", compression = "gzip", tar = "internal")
unlink("pkg", recursive = TRUE)
con <- file("pkg_1.0.tar.gz", open = "rb")
ex <- tempfile()
untar(con, files = "pkg/DESCRIPTION", exdir = ex)
#> Error in untar2(tarfile, files, list, exdir, restore_times) :
#> incomplete block on file
