I am using RStudio Version 1.3.1056 with R version 4.0.2 (2020-06-22) on Ubuntu 20.04.1 LTS.
I wanted to add the French spelling dictionary to RStudio, so I went to Global Options->Spelling->Install More Dictionaries. When I clicked on it, it waited a second and then the "Main dictionary language" changed to "Update dictionaries" with no other dictionaries listed. When I try to spellcheck a document, RStudio responds "An error has occurred: (String) : Dictionary not loaded.". I am unable to spellcheck in any language. I tried deleting completely the directory ~/.rstudio-desktop, but that did not fix the problem.
Does anyone have a solution to this problem? Is it a bug or am I doing something incorrectly?
