For the server, however, it’s Ubuntu 20.04, so it’s “Focal Fossa” we are looking for ( apparently a weird cat-creature). So if we are working with Mint 19.3, we need to look at Ubuntu 18.04, which is “Bionic Beaver” (what even is that?). And, what is the name of that one? The sources on CRAN site does not use the version numbers, they use the release names. Make sure to read the Ubuntu release notes. Linux Mint 19.3 is based on Ubuntu 18.04.

For instance, if we are wondering about Mint 19.3 Tricia, we go to the Mint website, and find the release notes, and somewhere in there it says: Other issues If you are running some Ubuntu spin-off, like Linux Mint, you need to first check which version of Ubuntu it is based on (it’s the last LTS). This one has to fit the version of Ubuntu. OK, no problem, we go to the Ubuntu page for R CRAN ( ), and we find the apt source line we need to add. But to do that, one has to know to look for the initial lines when starting R: R version 3.6.3 () - 'Holding the Windsock'Ĭopyright (C) 2020 The R Foundation for Statistical Computing OK, I looked at CRAN page and realized the R 4.0 issue. Package 'mnormt' is not available (for R version 3.6.3) Installation of package 'psych' had non-zero exit status Warning: dependency 'mnormt' is not availableĬontent type 'application/x-gzip' length 1724122 bytes (1.6 MB)ĮRROR: dependency 'mnormt' is not available for package 'psych'

Installing package into '/home/shiny/R/x86_64-pc-linux-gnu-library/3.6' However, psych hasn’t, so trying to install psych results in missing and uninstallable dependencies.

To get specific, I was trying to install psych package, which depends on mnormt package, and that package has moved to requiring R > 4.0 already. First, I install the stuff I want, but it turns out some packages on CRAN have already moved to requiring R > 4.0, meaning that the default R version in Ubuntu 20.04 (released in April 2020!) is already outdated to the point of being broken. I am installing R on a new Ubuntu 20.04 VPS. These errors are typically also hard to find, one has to skim the super long install log in the console to find the 1-3 relevant lines. Not only does it take a long time to compile so many packages, this step typically has to be repeated a few times due to unforeseeable errors. I love R and all, but it’s obnoxious to install. Here’s a whiny post on annoying R features.
