I have had the same problem with a specific package in R and the solution was I should install in the ubuntu terminal libcurl. Look at the information that appears above explaining to us that curl package has error installation.
I knew this about the message:
Configuration failed because libcurl was not found. Try installing:
* deb: libcurl4-openssl-dev (Debian, Ubuntu, etc)
* rpm: libcurl-devel (Fedora, CentOS, RHEL)
* csw: libcurl_dev (Solaris)
If libcurl is already installed, check that 'pkg-config' is in your
PATH and PKG_CONFIG_PATH contains a libcurl.pc file. If pkg-config
is unavailable you can set INCLUDE_DIR and LIB_DIR manually via:
R CMD INSTALL --configure-vars='INCLUDE_DIR=... LIB_DIR=...'
To install it I used the net command:
sudo apt-get install libcurl4-openssl-dev
Sometimes we can not install a specific package in R because we have problems with packages that must be installed previously as curl package. To know if we should install it we should check the warning errors such as: installation of package ‘curl’ had non-zero exit status.
I hope I have been helpful
