How to install VirtualBox - kdaisho/Blog GitHub Wiki

Host machine: Ubuntu

Download VirtualBox via browser

Download VirtualBox from Oracle website

Go to the directory that deb file was downloaded, then run:

sudo dpkg -i {DOWNLOADED_FILE_NAME}.deb

However when you try, you might get errors:

dpkg: dependency problems prevent configuration of virtualbox-{version}
virtualbox-{version} depends on liblzf1 (>= 1.5); however:
  Package liblzf1 is not installed.
virtualbox-{version} depends on libqt{version}help{version} (>= 1.5); however:
  Package libqt{version}help{version} is not installed.
...

Let's install those missing dependencies.

sudo add-apt-repository universe
sudo apt update
sudp apt install liblzf1 libqt{version}help{version}

Then, if you are prompted to run this, run it.

sudo apt --fix-broken install

Now the installation should work.

sudo dpkg -i {DOWNLOADED_FILE_NAME}.deb
