As most of you probably know, the latest version of Ubuntu has been released a couple months ago: Ubuntu 10.04 Lucid Lynx. (http://www.canonical.com/news/ubuntu-10.04-desktop-edition)
As it is another LTS release (3 year support on the Desktop version - which we use), we consider that it's important to have emc2 packages (along with the needed infrastructure: patched kernel, rtai, etc) for it. Our special thanks go to Moses McKnight (mozmck) who took the time (and responsability) to go through the daunting process of building all the packages and putting everything together in form of this LiveCD. Now we have: binary packages, a repository for them, and a LiveCD for easy testing and install. (this procedure took a longer period of time, until the packages/LiveCD were free of issues, and I would like to thank all testers that helped during this process). == note == Before describing download and install procedures I would like to point out that at this point the packages have been tested by a large number of people, and only a very few problems have been reported so far (on some exotic hardware with 6 core CPUs). However I do not encourage at this point to replace a working hardy install with the new lucid version, unless there is really good reason to do so. Ubuntu 8.04 Hardy Heron is still supported until april 2011, and as long as it's supported we will be building emc2 packages for it. The cases where you should chose Lucid over Hardy are: * new hardware that doesn't work on hardy * you're doing a brand new install * SMP support (more than one CPU and/or CPU core) * you just want to help with testing the new release == Installing/testing procedures: == 1. starting with a LiveCD (provides means for testing only, or even install if wanted) (the suggested way to try it out) Step 1: Download the iso from: http://www.linuxcnc.org/lucid/ubuntu-10.04-linuxcnc1-i386.iso (note: this URL might change in the future, reference http://www.linuxcnc.org/ for the latest download link, and for a description of known problems). Step 2: Check the MD5SUM (note: also mentioned at http://www.linuxcnc.org/, the latest one is: 5283b33b7e23e79da1ee561ad476b05f) Step 3: burn the image Step 4: boot it on your PC (Note: the LiveCD contains two modes: live/test and install. The Live version requires 384Mb RAM but an existing swap partition on the harddrive will be picked up, so it might be possible to boot the Live version on systems with less memory. The install mode needs as little as 256MB for installing). If you're happy with how it works/looks, install it on your machine. Step 5: report problems (&successes) encountered 2. starting with an existing Ubuntu 10.04 Lucid Lynx install Step 1: Install Ubuntu 10.04 Step 2: Once you have installed Ubuntu , get the install script from here: http://www.linuxcnc.org/lucid/emc2-install.sh , choose "Save to Disk" and click OK. Step 3: Now an emc2-install.sh icon will appear on your Desktop. Right-click that icon, select Properties. Go to the Permissions tab and check the box for Owner: Execute. Close the Properties window. Step 4: Now double-click the emc2-install.sh icon, and select "Run in Terminal". A terminal will appear and you will be asked for your password. Step 5: When the installation asks if you are sure you want to install the EMC2 packages, hit Enter to accept. Now just allow the install to finish. Step 6: When it is done, you must reboot (System > Log Out > Restart the Computer) - once you have rebooted you can run EMC2 by selecting it on the Applications > CNC menu. Step 7: If you aren't ready to set up a machine configuration, try one of the sim configurations; they run a "simulated machine" that require no attached hardware. == Reporting problems & getting help == Reporting issues/problems/nags/ideas for improvements or anything else, can be done via email (on this list), via IRC (#emc-devel on irc.freenode.net) or via bug-reports at: http://sourceforge.net/tracker/?group_id=6744&atid=106744 Thanks for your patience, and for all the help to make it another great release.
