System is Windows 10 x64, using R v4.0.5 and Rstudio v1.4.1106. Recently clean installed Windows. Tried reinstalling R and Rstudio multiple times after too.
I'm trying to use packages like tidyverse and shiny. Shiny has dependencies of httpuv and later, so when I went to install them I get the error "Cannot open URL 'https:// ...": HTTP status was '404 Not Found'", also shown below. I went into the repository on a browser and saw that the package indeed doesn't exist. I've tried many repositories (as listed in Tools -> global options -> packages) other than the cran.rstudio.com but they also don't have the packages "later_1.2.0.zip" or "httpuv_1.6.0.zip" that rstudio is attempting to download.
Am I doing something wrong here, like working with an incompatible version of R (v4.0.5)? Why is rstudio trying to download packages that don't exist? My temporary workaround is separately downloading the packages I need on https://cran.r-project.org/ and installing them as tar.gz, but hopefully there's a simpler solution to all this. Thanks in advance
