Hi all, The following fails for me (on OS X, although I imagine it's the same on other platforms using libcurl):
options(download.file.method = "libcurl") options(repos = c(CRAN = "https://cran.rstudio.com/", CRANextra = "http://www.stats.ox.ac.uk/pub/RWin")) install.packages("lattice") ## could be any package gives me: > options(download.file.method = "libcurl") > options(repos = c(CRAN = "https://cran.rstudio.com/", CRANextra = "http://www.stats.ox.ac.uk/pub/RWin")) > install.packages("lattice") ## coudl be any package Installing package into ‘/Users/kevinushey/Library/R/3.2/library’ (as ‘lib’ is unspecified) Error: Line starting '<!DOCTYPE HTML PUBLI ...' is malformed! This seems to come from a call to `available.packages()` to a URL that doesn't exist on the server (likely when querying PACKAGES on the CRANextra repo) Eg. > URL <- "http://www.stats.ox.ac.uk/pub/RWin" > available.packages(URL, method = "internal") Warning: unable to access index for repository http://www.stats.ox.ac.uk/pub/RWin Package Version Priority Depends Imports LinkingTo Suggests Enhances License License_is_FOSS License_restricts_use OS_type Archs MD5sum NeedsCompilation File Repository > available.packages(URL, method = "libcurl") Error: Line starting '<!DOCTYPE HTML PUBLI ...' is malformed! It looks like libcurl downloads and retrieves the 403 page itself, rather than reporting that it was actually forbidden, e.g.: > download.file("http://www.stats.ox.ac.uk/pub/RWin/bin/macosx/mavericks/contrib/3.2/PACKAGES.gz", tempfile(), method = "libcurl") trying URL 'http://www.stats.ox.ac.uk/pub/RWin/bin/macosx/mavericks/contrib/3.2/PACKAGES.gz' Content type 'text/html; charset=iso-8859-1' length 339 bytes ================================================== downloaded 339 bytes Using `method = "internal"` gives an error related to the inability to access that URL due to the HTTP status 403. The overarching issue here is that package installation shouldn't fail even if libcurl fails to access one of the repositories set. > sessionInfo() R version 3.2.2 (2015-08-14) Platform: x86_64-apple-darwin13.4.0 (64-bit) Running under: OS X 10.10.4 (Yosemite) locale: [1] en_CA.UTF-8/en_CA.UTF-8/en_CA.UTF-8/C/en_CA.UTF-8/en_CA.UTF-8 attached base packages: [1] stats graphics grDevices utils datasets methods base other attached packages: [1] testthat_0.8.1.0.99 knitr_1.11 devtools_1.5.0.9001 [4] BiocInstaller_1.15.5 loaded via a namespace (and not attached): [1] httr_1.0.0 R6_2.0.0.9000 tools_3.2.2 parallel_3.2.2 whisker_0.3-2 [6] RCurl_1.95-4.1 memoise_0.2.1 stringr_0.6.2 digest_0.6.4 evaluate_0.7.2 Thanks, Kevin ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
