Missing RStudio Desktop Tarball for Ubuntu 16.04+ (64-bit)

The download page doesn't list a tarball for "RStudio 1.1.414 - Ubuntu 16.04+/Debian 9+ (64-bit)". Is this intentional?

Getting the package installed by an admin is a lot of effort in my organization. Up to version 1.1.383, the tarball has served me well.
