[R-pkg-devel] SSL error during devtools::release()

[Jennifer Bryan]

If you are in a position to install the development version of git2r, that
is worth a shot.

devtools is calling git2r, which uses libgit2 (among other things), not the
system Git you are probably using when you "push to GitHub".

Your difficulty has a lot in common with this issue:
