Upgrade paths
Ubuntu supports the ability to upgrade from one LTS to the next LTS in sequential order. For instance, a user on Ubuntu 16.04 LTS can upgrade to Ubuntu 18.04 LTS, but cannot jump directly to Ubuntu 20.04 LTS. To do this, the user would need to upgrade twice from Ubuntu 16.04 to Ubuntu 20.04.
For a complete list of releases and current supporting status see the Ubuntu Wiki Releases page.
Upgrade checklist
Check the release notes for the new release for any known issues or important changes.
- Fully update the current system. The upgrade process works best when the current system has all the latest updates installed. It is also suggested that users reboot the system after all the updates are applied to verify a user is running the latest kernel.
sudo apt update sudo apt upgrade sudo reboot Users should check that there is sufficient free disk space for the upgrade. Systems with additional software installed may require a few gigabytes of disk space.
The upgrade process takes time to complete, be patient.
Third-party software repositories and PPAs are disabled during the upgrade. However, any software installed from these repositories is not removed or downgraded. Software installed from these repositories is the single most common cause of upgrade issues.
- Back up all data. Upgrades are normally safe, however, there is always the chance that something may go wrong.
Upgrade
It is recommended to upgrade the system using the do-release-upgrade command on server edition and cloud images. This command can handle system configuration changes that are sometimes needed between releases.
do-release-upgrade
To check for any available new versions to which you can upgrade, run the following command:
do-release-upgrade -c
This will check Ubuntu’s servers for any available updates and informs you which version of Ubuntu you’ll be upgrading to.
To begin this process, run the following command:
sudo do-release-upgrade
Upgrading to a development release of Ubuntu is available using the -d flag:
sudo do-release-upgrade -d

Setup an IKEv2 server with strongSwan
IKEv2, or Internet Key Exchange v2, is a protocol that allows for direct IPSec tunnelling between networks. It is developed by Microsoft and Cisco (primarily) for mobile users, and introduced as an updated version of IKEv1 in 2005. The IKEv2 MOBIKE (Mobility and Multihoming) protocol allows the client to main secure connection despite network switches, such as when leaving a WiFi area for a mobile data area. IKEv2 works on most platforms, and natively supported on some platforms (OS X 10.11+, iOS 9.1+, and Windows 10) with no additional applications necessary.
