printf '\nexport QT_STYLE_OVERRIDE=gtk\n' | sudo tee -a ~/.profile

# Make RStudio look a bit nicer
sudo apt install qt5-style-plugins
echo "export QT_QPA_PLATFORMTHEME=gtk2" >> ~/.profile

rstudio depends on libclang-dev; however:
Package libclang-dev is not installed.

error processing package rstudio (--install):

Well I guess you need to install libclang-dev
sudo apt install libclang-dev
