  Fix broken packages first.

Ubuntu 14.04 LTS has openscad 2013.01. I would like to use a newer version of openscad. I'm having trouble building it, so I am also trying to a install nightly build binary. I'm following the instructions here: http://www.openscad.org/downloads.html I added deb http://download.opensuse.org/repositories/home:/t-paul/xUbuntu_14.04/ ./ to /etc/apt/sources.list.d/openscad.list (I had to create the file) I also ran wget -qO - http://files.openscad.org/OBS-Repository-Key.pub | sudo apt-key add - Now openscad-nightly:i386 appears in synaptic for installation, but if I try to install it, synaptic shows a red exclamation mark and displays the message: Could not apply changes! Fix broken packages first. I also tried to install it from the command line: sudo apt-get install openscad-nightly:i386 Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming.

It seems very difficult to run a recent version of openscad on this version of Ubuntu. Does anyone know how to do this? -- View this message in context: http://forum.openscad.org/How-to-run-a-recent-openscad-on-Ubuntu-14-04-LTS-tp17241.html Sent from the OpenSCAD mailing list archive at Nabble.com.

I added
   deb

I also ran
   wget -qO - http://files.openscad.org/OBS-Repository-Key.pub | sudo

Well, I have a theory about how to proceed, but hopefully there is a better way. I think this could be made to work by building OpenSCAD from the sources. Any libraries that Ubuntu 14.04 refuses to install (because they are too new, like libscintilla2) can also be built from sources and installed in /usr/local. I am also attempting to get the latest OpenSCAD running on Ubuntu, but my approach is to first upgrade to Ubuntu 16.04. And in order to make that work (I was previously running 14.04), I had to download the 16.04 ISO and do a fresh install, as it seems that no upgrade is currently possible. And uni-get-dependencies.sh is even more broken on 16.04 than it is on 14.04, so I have some work to do. Ubuntu 16.04 now supports "snap packages" which are supposed to eliminate this kind of dependency hell. Maybe in the future somebody will build an OpenSCAD Ubuntu snap package.

Adding this should resolve the issue. ciao, Torsten.

But only when the version number bumps to 16.04.1 does the upgrade manager consider it as an upgrade for 14.04 Long Term Stable (*) users. If you want to upgrade now you'll have to force it somehow. I'm pretty sure that's possible, as I upgraded to 16.04 (from 15.10 over a month ago). Roger.
