I found that for:
is unable to connect to https://r.research.att.com/el-capitan/R-devel/R-devel-el-capitan-signed.pkg (because the file does not exist, only R-devel-el-capitan.pkg).
Is it possible to fix it somehow?

I recommend you only test r-devel in linux, and use r-release or r-oldrel on macos. CRAN doesn’t publish OSX binary packages for r-devel: https://cran.r-project.org/bin/macosx/el-capitan/contrib/r-devel/
However, previous builds using r-devel on osx where working (e.g. here two months ago) when downloading R-devel-el-capitan-signed.pkg from research att. Now at https://r.research.att.com/el-capitan/R-devel/ there exists a file called R-devel-el-capitan.pkg. Could this be just an issue of a name change?
I mean, if we should not test r-devel on OSX, I would have expected that previous builds also failed.
R-devel constantly changes and may break any day. That’s why it’s called devel. It seems indeed broken now due to the changed filename.
Ok. So if it is better to avoid the combination
r-devel (unless there is some special need I guess), maybe it should be documented at https://docs.travis-ci.com/user/languages/r/ for future users? Thank you again for clarifying the issue.
I’m trying to get a package to Bioconductor, and they do check with R-devel on MacOS. They have provided a link to R-devel http://r.research.att.com/el-capitan/R-devel/R-devel-el-capitan.pkg. I can simply run R CMD check and Bioc check on my computer, but it would be nice to automatically test on Travis.
