Reinstall VirtualBox on Ubuntu & CentOS

by

0

For Ubuntu

To remove virtualbox

sudo dpkg --list virtualbox-*
sudo apt autoremove --purge virtualbox*
dpkg -l virtualbox* | grep ^i

Remove all PPAs from sources.list and source.list.d directory

mkdir ~/apt-tmp
sudo mv /etc/apt/sources.list.d/* ~/apt-tmp

Make sure there is nothing except official repositories sources in /etc/sources.list. And update your sources:

sudo apt update

Now we can search to see which versions are available to install:

apt-cache madison virtualbox | grep -iv sources

Which produces an output like this:

virtualbox | 5.0.32-dfsg-0ubuntu1.16.04.2 | http://mirrors.kernel.org/ubuntu xenial-updates/multiverse amd64 Packages
virtualbox | 5.0.18-dfsg-2build1 | http://mirrors.kernel.org/ubuntu xenial/multiverse amd64 Packages

Then I would install the last version mentioned in xenial-updates: Continue reading “Reinstall VirtualBox on Ubuntu & CentOS” »
