LTS versions are released every 2 years. The last LTS release was Ubuntu 16.04 LTS (codenamed Xenial Xerus).

Ubuntu LTS versions

Ubuntu Server changes

These are some of changes in Ubuntu 18.04 LTS relevant to Fuga users. For the complete overview, see the release notes for Ubuntu 18.04 LTS.


One of the biggest changes that you will notice is that ifupdown has been replaced with netplan.io. For most usecases you don’t have to change anything here, but in more complex setups you might want more control over your network configuration:

The old ifupdown configuration was located in /etc/network/interfaces. This will now display a warning that it has been depricated.

root@ubuntu1804:~# cat /etc/network/interfaces
# ifupdown has been replaced by netplan(5) on this system.  See
# /etc/netplan for current configuration.
# To re-enable ifupdown on this system, you can run:
#    sudo apt install ifupdown

A netplan.io config can now be found in /etc/netplan/50-cloud-init.yaml.

root@ubuntu1804:~# cat /etc/netplan/50-cloud-init.yaml
# This file is generated from information provided by
# the datasource.  Changes to it will not persist across an instance.
# To disable cloud-init's network configuration capabilities, write a file
# /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg with the following:
# network: {config: disabled}
    version: 2
            dhcp4: true
                macaddress: fa:16:3e:b6:2d:ea
            set-name: ens3

More information on netplan.io can be found here.

QEMU 2.11.1

QEMU has been updated to the 2.11.1 release.

QEMU in Ubuntu 18.04 now has RDMA support enabled as over the past year much unification in the RDMA-core project has occured.

Migrations from former versions are supported just as usual. When upgrading it is always recommended to upgrade the machine types, allowing guests to fully benefit from all the improvements and fixes of the most recent version.

libvirt 4.0

libvirt has been updated to version 4.0. The packaging now builds libvirt storage drivers as pluggable libraries. This slims down the installation requirements but some drivers of less general interest will now be found in universe. (ex: gluster, sheepdog, zfs)


The recommended server for the NTP protocol on Ubuntu 18.04 LTS is now Chrony in stead of NTPD. It is highly recommended not to change this back to NTPD, as NTPD will only receive best-effort security maintenance from now on.


The version was updated to 18.2. Notable new features include:

  • New cloud-init command-line tools available: status, analyze and clean


Nginx was updated to version 1.14.0. New features include the mirror module, HTTP/2 push, and the gRPC proxy module.


PHP was updated to version 7.2.x.


Apache was updated to version 2.4.29. Additionally, HTTP/2 support is now enabled in 18.04.

Vulnerabilities in multiple CPU architectures (updated Jan, 18th)

Update Jan 18th This morning, January 18th at 06:00 CET, the implementation of the security patch for our network controllers didn’t go as expected. After patching and restarting the control layer at 07:15 CET, networking encountered a bug. It took us until 08:13 CET to get networking operational. From this point on, there were no issues with running services, however, our API backend remained unstable until 13:15 CET. The timeline is available on our status page.
