How to remove preinstalled VirtualBox Guest Additions from Ubuntu

Removing Preinstalled VirtualBox Guest Additions from Ubuntu

Ubuntu 18.04 (and 19.03) has an older version of the VirtualBox Guest Additions preinstalled. The "normal" method of using the VirtualBox Guest Additions image (VBoxGuestAdditions.iso) to upgrade doesn't work unless the preinstalled Guest Additions are removed first.

Removing the preinstalled Guest Additions

  1. Run the following commands:

    

    2. 



sudo apt remove virtualbox-guest-utils

                SQLcl installation on Windows 10
              
          

        

      

        

  

      

    
    

  1. Add SQLPATH as a user environment variable, pointing to %USERPROFILE%\Documents\Oracle
    2. 

  2. Add C:\Program Files\SQLcl\bin to system PATH envrionment variable
    3. 

  3. Rename C:\Program Files\SQLcl\bin\sql.exe to _sql.exe
    4. 

  4. Copy sql.cmd to C:\Program Files\SQLcl\bin
    5. 



Note: Portions of sql.cmd are adapted from Oracle's sql.bat, which was used to start older versions of SQLcl on Windows, and from Glen Conway's excellent hints in this thread in the Oracle SQLcl Community.

How to install/upgrade/downgrade VirtualBox Guest Additions for Linux from the command line


The basic steps used are from https://www.vagrantup.com/docs/virtualbox/boxes.html.


Run the script below to install, upgrade or downgrade the VirtualBox Guest Additions for Linux. The script will install the latest version by default, but also allows specifying a different version as an argument.
Note: The script requires the bzip2 and wget packages.


If the guest already has a shared folder with the host, one can also copy VBoxGuestAdditions.iso from the VirtualBox installation folder (usually C:\Program Files\Oracle\VirtualBox on Windows) instead of downloading the Guest Additions using wget. However, mounting the .iso from a shared folder probably won't work--the file needs to be copied to the guest's filesystem.

Automatically Installing SQLcl for Oracle's Vagrant Database Boxes


Oracle provides Vagrant configuration files for installing several versions of Oracle Database in the oracle/vagrant-boxes GitHub repository. The Oracle Database box installers allow running user-defined scripts automatically after the database has been set up and started. This document provides instructions and scripts that use this functionality to install SQLcl.


Overview:


    

  • The procedure below installs SQLcl for the vagrant user only.
    • 

  • Oracle envrionment variables are set for the vagrant user (using oraenv), so that SQLcl can find the database's tnsnames.ora file, and the vagrant user can run the database utilities, like SQL*Plus and RMAN.
    • 

  • SQLcl requires Java 1.8 or above. The procedure installs the latest OpenJDK from the Oracle Linux Yum Server, and creates a script to allow the vagrant user to run SQLcl without Java version conflicts, while preserving the
