Linuxcnc 2.5 and Ubuntu 10.04 ugrade
I'm using Linuxcnc 2.5 on Ubuntu 10.04. Being that 10.04 is no longer supported I'd like to upgrade to 12.04 AT LEAST.
But being somehow of an ignorant on Ubuntu stuff, specially the Real Time Kernel stuff, I'd like to ask a few questions.
The Linuxcnc upgrade "How To's" describe either how to use fresh install 12.04 Ubuntu and then installing Linuxcnc 2.7 OR upgrading from an older version of Linuxcnc to 2.7 but keeping the same Ubuntu version. I have several other programs installed in my Ubuntu 10.04 and specially programs running with Wine which took a lot of effort (and time, specially) to get running, so starting with a fresh Ubuntu or Debian install is out of the question unless I have no other choice.
So my questions are:
(1) Can upgrade Linuxcnc to v2.7 and then upgrade to Ubuntu 12.04 or later? Or, should I uninstall Linuxcnc, upgrade Ubuntu and then install Linuxcnc 2.7?
(2) I have an AMD Athlon X2 64, currently my Ubuntu runs 32 bit, but have seen a few posts of people using Ubuntu 14.04 64 bit and making it work. Only today I learned that Linuxcnc already had version 2.7 , so, since I'm in a huge delay as far as versions go, is it still true that only Ubuntu 12.04 32 bit is supported for Linuxcnc? - The Answer is YES from what I can read in the "Getting Linuxcnc" page, but just want to be sure.
(3) How will the latency test be affected by upgrading to 12.04? Will it be a big issue or should I not worry?
(4) In "Updating to Linuxcnc", section 2.2 mentions changes that have to be made to the config file if I use a paralell port driver. How do I know if I have to change this? If so, how do I change it, do I open it as a text file and make the changes? I didn't find a way of doing so using Stepconfig.
Thanks for any help and specially understand that although I have some programming background (self-tought) most of this stuff is about the inner workings of the operating system itself and over my knowledge. I searched pages and pages of the Linuxcnc forum with out finding a direct to the point, clear answer to my questions.
Have a great day/night,
Alfredo

That said, If you upgrade, you will have to reinstall a real time kernel for Linuxcnc to use, and probably reinstall Linuxcnc.
It will almost certainly easier to just start over. Good luck with what ever route you choose.
If you have space on your drive, you could possibly set up a new partition or two, to install and try out some other options, without loosing your old system

So I'll uninstall Linuxcnc, upgrade Ubuntu and re-install. If something goes wrong with the other programs I'll start over.
I've been thinking about a third partition, I'll see into that... one for Windows, one stable Ubuntu and another to test maybe...
What about this?:

Still not sure I understand that part
Thanks again!!

The supported distro is debian wheezy... however I don't care for it. Ubuntu 12 is not supported.
But in the install instructions here: linuxcnc.org/docs/html/getting-started/getting-linuxcnc.html section 7.2 describes how to install on Precise, it confuses me... I'll see.
It is not just install a OS and install LinuxCNC, you must install a real time kernel.
I know, I know, when I say "install" I mean following all the steps in the Linuxcnc site, including the RT Kernel
If your not purchasing new hardware you don't need a new OS.
The problem is, Ubuntu 10.04 is no longer supported, so for other programs I need this is becoming an issue, even with Firefox I'm starting to get alerts, so I need to upgrade
Thanks for all your comments, I'll fix it probably with a new partition to try out before. This would allow me to work on it while keeping a working OS to machine during the day and fiddle with the new setup at nights, I remember when I first installed it took me a while to get everything working properly. The LiveCD option didn't work for me on my first attemp, maybe will try it out this time.
Still, I worry more about the (4) in my comment below, cause I don't really understand what it refers to. Although this issue is not mentioned on the fresh install pages. It's all too confusing for us people who have no real experience with this stuff.

When I tried the debian wheezy live it dies at eth0 not enabled and goes no further.
I'm not much of an expert, but maybe you could try a new Live CD, sometimes they fail for no reason and I just do another copy and it works fine.

Good luck solving your problem, hope a new cd will help you.
Trying to mark this thread as solved but can't seem to find how, if possible
