Ok, Uwe was kind enough to take me to task off-list and I can now confirm that I _can_ replicate the URL issue locally by ensuring all three of
- recent enough r-devel build (that was true, I may add that the rocker/r-devel and rocker/drd containers I look after can help) - built with libcurl support so check capabilities()[["libcurl"]] (that was also true for me) - CRAN incoming checks turned on (and that was my issue) One way to ensure the last point is to have a file ~/.R/check.Renviron-Rdevel which I had (but where I had commented out 'incoming' as it can take a moment). Current values below, with thanks to Uwe for the reminder. I reiterate that this really should be part of R CMD check --as-cran. Maybe one day it will be.
