There is no current release of this source package in 18.04 (Bionic Beaver). However, openscad-mcad exists, which depends on openscad, so that's obviously an error.

  • Why is the dependency obviously an error? – Karl Richter Apr 24 '18 at 11:13
  • 18.04 is now supported, the package is still missing (with an open bug report), and the question/answer should now be valid. – pim Apr 28 '18 at 10:09
  • The package exists in a ppa as described here – Samveen Nov 2 '18 at 16:30
  • There's a snap here that I can confirm works for Ubuntu 18.04: snapcraft.io/openscad – Nathaniel M. Beaver Jun 1 at 21:37

It seems openscad is neither in 18.04 nor in 18.10, I just opened a bug here, feel free to subscribe to it.

In the meantime, here is a procedure to install openscad from the PPA:

sudo add-apt-repository ppa:openscad/releases
sudo apt-get update
sudo apt-get install openscad

  • Doesn't work on my Kubuntu 18.04. Apt install complains with this error: openscad : Depends: libqt5scintilla2-12v5. This lib is supposed to be in the universe repo, but doesn't appear to be there either. – Scott Mar 29 '19 at 22:58

In Ubuntu 18.10

For this Ubuntu release, OpenSCAD is neither in the official repos nor in the ppa:openscad/releases PPA (see?). Installing the nightly build as a Snap package is a viable short-term alternative:

sudo snap install openscad-nightly

Using libraries in the OpenSCAD Snap: Like any OpenSCAD installation, it comes with one bundled library of CAD functions that you can use out of the box. You would use include <….scad> statements with paths relative to the installation library location, which is here:


Since this is only meant for libraries bundled with OpenSCAD and Snap installation directories are not writable anyway, you would install other libraries manually into the built-in library location, which for the Snap package is this:


You can also set a "nicer" user-defined library location via $OPENSCADPATH.

In Ubuntu 19.04

The good news is that starting with this Ubuntu release, the brand new version OpenSCAD 2019.01~RC2-2 will be in the official Ubuntu repositories (see). Then, installation will be easy and disk space saving again:

sudo apt install openscad
