UPDATE to given issue. In order to solve this given issue with the error prompts that I received at the terminal and when I ran a VM, the issue didn't relate to a bug, but rather a few configuration problems I had. After scurrying the Internet I discovered that Secure Boot in my bios was stopping VirtualBox from completely downloading. This is due to Secure Boot not allowing third-party programs from completely executing. In order to turn this off I accessed my bios settings upon boot and disabled Secure Boot. To do this it varies from system to system but there's a plethora of information to do this on the Web. However after this I found that Virtual Box was still not working properly. By looking on the Internet some more I discovered that two versions of VirtualBox were on my host (specifically VirtualBox 5.0 and 5.1). In order to discover this I typed the following script at the command line: dpkg --list | grep virtualbox >From here I typed that following lines to uninstall multiple versions: sudo apt-get remove virtualbox-\* sudo apt-get purge virtualbox-\* Then I followed these scripts to reinstall VirtualBox: [Add Virtualbox Repository] $ sudo sh -c "echo 'deb http://download.virtualbox.org/virtualbox/debian '$(lsb_release -cs)' contrib non-free' > /etc/apt/sources.list.d/virtualbox.list" [Import Oracle Public Key] $ wget -q http://download.virtualbox.org/virtualbox/debian/oracle_vbox.asc -O- | sudo apt-key add - [Install dependency packages] $ sudo apt-get install dkms [Update Repository Index] $ sudo apt-get update [Install VirtualBox] $ sudo apt-get install virtualbox-5.1 I hope this helps as it took me days of troubleshooting to discovery what I needed to do. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1654456 Title: package libidn11:amd64 1.32-3ubuntu1.1 failed to install/upgrade: package libidn11:amd64 is already installed and configured To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dpkg/+bug/1654456/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
