Alter protocol version installing from github

Question

I try to install a package from GitHub using this:

library(devtools)
install_github(dosorio/Peptides)

but I receive this error

Downloading github repo dosorio/Peptides@master Error in function (type, msg, asError = TRUE) : error:1407742E:SSL routines:SSL23_GET_SERVER_HELLO:tlsv1 alert protocol version

this error happens with all attempts to install other r package from GitHub

I user 3.0.2 R version in window/Rstudio.

Does it have to do with the R version or anything else?

install_github need a character vector install_github('dosorio/Peptides'). Other than that, it's working on my machine with R 3.4.4 — GGamba

I had the same issue and i solved the the following commands:

git config --global --list
git config --global --unset http.sslVersion
git config --global --add http.sslVersion tlsv1.2
