linux - Installing devtools fails beacuse of dependency, but dependency is not available for the R version I have -

- 

configure: error:  ---------------------------------------------   openssl library required    please install:   libssl-dev (deb) or openssl-devel (rpm) --------------------------------------------- see `config.log' more details error: configuration failed package ‘git2r’  * removing ‘/home/udi/r/x86_64-pc-linux-gnu-library/3.2/git2r’ error: dependency ‘openssl’ not available package ‘httr’  * removing ‘/home/udi/r/x86_64-pc-linux-gnu-library/3.2/httr’ error: dependencies ‘httr’, ‘git2r’ not available package ‘devtools’  * removing ‘/home/udi/r/x86_64-pc-linux-gnu-library/3.2/devtools’

however, when try install libssl-dev (i have ubuntu 14.04.3) got message "‘libssl-dev’ not available (for r version 3.2.2)".

any idea do? download new r version or there other solution? thank in advance.

that system package - not r package. command line can run

sudo apt-get install libssl-dev
