I'm experimenting with running RStudio directly on Linux (I still rely on RStudio on Windows, or RStudio on WSL2+Windows).
I installed RStudio and R on Ubuntu 21.04, which is the latest release of that distribution, but isn't a LTS like 20.04.
When I look at, say, the Rstudio package manager site, everything is tied to LTS releases. So will it not work with 21.04? Here it explicitly cites a URL that is from the focal (20.04) release:
And, more broadly, what are the problems I'm likely to encounter when running a non-LTS release?
