Now either rename or delete the contents of the folder ParaView. For example, to update openfoam6, simply open a terminal and enter the following commands: sudo apt-get update sudo apt-get install --only-upgrade openfoam6. For Ubuntu 16.04LTS, 18.04LTS, 19.04, 19.10, 20.04 LTS, Windows 10 and Docker images for other Linux and macOS Windows Explorer should open up and show the contents of the AddOns folder. Don’t forget to create a new ParaView folder, so that it can be used with the ParaView installer. Otherwise, ParaView 5.6.0 comes as standard with a new installation of the openfoam6 or openfoam-dev packs for Ubuntu 18.04LTS and 18.10 as described in Download v6 | Ubuntu.
