I'm not sure if this is the proper venue or if this is better addressed as a github issue, but it seems libcurl is not installed on ubuntu-latest. See https://github.com/aadler/Delaporte/runs/1644549721?check_suite_focus=true. Specifically:
* installing *source* package ‘curl’ ...
** package ‘curl’ successfully unpacked and MD5 sums checked
** using staged installation
Package libcurl was not found in the pkg-config search path.
Perhaps you should add the directory containing `libcurl.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libcurl' found

------------------------- ANTICONF ERROR ---------------------------
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=...'
