r - Ubuntu, how to deal the error "<stdin>:1:10: fatal error: git2.h: No such file or directory"?

Question

I am trying to install the easypackages R package on R 3.6.1 on miniconda, which requires the installation of the gert package, that fails. Here's the log:

* installing *source* package ‘gert’ ...
** package ‘gert’ successfully unpacked and MD5 sums checked
** using staged installation
Found pkg-config cflags and libs!
Using PKG_CFLAGS=
Using PKG_LIBS=-lgit2
----------------------------- ANTICONF -------------------------------
Configuration failed to find libgit2 library. Try installing:
 * brew: libgit2 (MacOS)
 * deb: libgit2-dev (Debian, Ubuntu, etc)
 * rpm: libgit2-devel (Fedora, CentOS, RHEL)
If libgit2 is already installed, check that 'pkg-config' is in your
PATH and PKG_CONFIG_PATH contains a libgit2.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=...'

I already installed the libgit2-dev Ubuntu package but it did not solve the problem. Any suggestion on how to fix it? I am using an Ubuntu 16.04.7 LTS operating system.

Thank you
