I installed a local shiny server on a Ubuntu 20.04 LTS. The R web app works correctly, I have tested in RStudio.
But when I try to deploy it on a shiny server it's missing packages and after I install them via the R console, it continues to tell me I'm missing the packages.
After a little google search, some people tell me it's because of the user in which it runs de shiny server service. I don't know if it's my case or not.
thank you and good day.
