Updating RStudio server on Ubuntu server 20.04.2 LTS

Problem: R version 4.1.1 crashes when creating plots with ggplot2 and RStudio server version 4.1.1106. 

Solutions from the internet:

• Downgrading to R 4.0.5 apparently works.
• Adding x11() in front of the plot code may work as well.
• Updating RStudio server is supposed to work as well.
  
  

How to update RStudio server:

Check here for the latest files: https://www.rstudio.com/products/rstudio/download-server/debian-ubuntu/

sudo apt-get install gdebi-core

wget https://download2.rstudio.org/server/bionic/amd64/rstudio-server-2021.09.0%2B351-amd64.deb 

sudo gdebi rstudio-server-2021.09.0+351-amd64.deb

sudo ufw allow 8787/tcp #optional, skip if you haven't enabled firewall yet

Result: Yes, updating RStudio server worked for me.
