We’re preparing Lubuntu 15.04, Vivid Vervet, for distribution in April 2015. With this Beta pre-release, we are now at the stage of being semi stable. However pre-releases are not suitable for a production environment.

NOTE: This is an beta pre-release. Lubuntu Pre-releases are NOT recommended for:

  • Regular users who are not aware of pre-release issues
  • Anyone who needs a stable system
  • Anyone uncomfortable running a possibly frequently broken system
  • Anyone in a production environment with data or workflows that need to be reliable

Lubuntu Pre-releases ARE recommended for:

  • Regular users who want to help us test by finding, reporting, and/or fixing bugs
  • Lubuntu developers

Getting Lubuntu 15.04 Beta 2

Download a Disk Image

Instr uctions for burning the image to a DVD or USB flash drive can be found on the Burning ISO Howto.

We recommend you learn how to check your image file so your pre-release is as it’s supposed to be. Compare your MD5 checksum with the correct ones found alongside the images.

Beta 2 Highlights

  • LXQt is still in development, so Vivid Vervet is another bug fix release. A late regression in the desktop installer for 32 bit means there is no Desktop installer for this milestone but it does not affect the alternate installer.

Software Updates


Linux Kernel

The Beta 1 Vivid Vervet snapshot includes the 3.19.0-10.9 Ubuntu Linux kernel which is based on the the upstream v3.19 Linux kernel. The 3.16 release includes increased ARM support and improved drivers (Radeon, Intel, and Nvidia graphics), to name a few; additional highlights are described here.

Known Problems

Lubuntu Desktop Installer

  • No option to install alongside a btrfs partition: 1403624

  • Install alongside offers to install to USB boot media instead of hard drive: 1403620

Lubuntu Alternate Installer


Development of Lubuntu 15.04, the Vivid Vervet is ongoing and bugs are fixed every day. Before reporting bugs, please ensure your system is up to date. For verifying installation related bugs, updated disk images are available from Daily bootable images for standard PCs/laptops/netbooks.

Please feel free to contact us with feedback.
