When behind a corporate firewall with self signed certificate and download.file.method == "libcurl", connection to CRAN mirror fails:
Warning: unable to access index for repository https://cran.rstudio.com/src/contrib: cannot open URL 'https://cran.rstudio.com/src/contrib/PACKAGES'
This is tied to R's changes to libcurl and is resolved in 4.2.2 (I believe).
THE ISSUE: However, under R 4.2.1 and with a failure to connect securely to a CRAN mirror, RStudio IDE's "Packages pane > Update" reports "All packages are up to date".
When unable to connect to CRAN, RStudio should not report everything being up to date.
