Recent days ago I uppgraded to the new LTS version of Ubuntu, I don't know if that information could help and I'm ussing 4.0.0 version of R.
Actually in this computer I haven't installed a lot of packages, I've never gotten an error like this.
The error is when I try to install "quantmod", I receive this, and the same with "car".
And I'm not an Ubuntu expert, I don't know how to continue.
Help please.
Hi cruddy,
The solution is right there in the error message you received. You are missing some system libraries, which for a Debian-based distro like Ubuntu means you should install libcurl4-openssl-dev. Open up a terminal (CTRL+ALT+t) and type
sudo apt install -y libcurl4-openssl-dev
Then try and re-install the packages in R.
PS --- There are a couple of alternative R package installation methods that automatically take care of this kind of thing (e.g. pre-compiled binaries and installing system dependencies on Ubuntu). But the above solution is probably the easiest for you rn.
