Updating 2.8

I have (I think stretch-usrspace-AM64) on a spare drive that I want to play with Installed this last June.

This is what I get from uname -a
Linux debian 4.9.0-3-rt-amd64 #1 SMP PREEMPT RT Debian 4.9.30-2+deb9u2 (2017-06-26) x86_64 GNU/Linux

I would like to bring it up to date before I start to configure it for a machine. So what is the procedure to do this please.

I can do this with 2.7.13 but not sure with the 2.8

If you installed using one of the Linuxcnc iso you can simply update using apt or synaptic. To change version s you must change the repository to the new one then update

Thanks for the reply. Yes it was installed from an linuxcnc iso. But sorry you confused me with the change version bit.
Would you mind giving me the step by step method for me to update (as it appears to be different than the 2.7.13 stable version)

2.8 is currently the development version of Linuxcnc "Master".
To change from 2.7 to 2.8 you have to change the repositories your computer is pulling updates from.
The simplest way I know is to do it using Synaptic.
1st open Synaptic.
Click on the "Settings" menu.
Click on "Repositories"
In the window that pops up scrol down the repository list to find the ones for Linuxcnc.
There should be one or more that say something like "buildbot.linuxcnc.org/" and one of those with a section called "2.7-rtpreempt".
Uncheck that one and add a new repository (by clicking "New") with the same URI and distribution name as the one for 2.7, but with the section "master-rtpreempt" and make sure that it is checked as enabled.
Close the repository window.
Then in Synaptic click Reload, Mark all upgrades, and Apply.

Synaptic will then download and install Linuxcnc 2.8 on your computer.

Thanks for the quick reply Todd.

I already have 2.8 installed ( I think) This is what I get from uname -a
Linux debian 4.9.0-3-rt-amd64 #1 SMP PREEMPT RT Debian 4.9.30-2+deb9u2 (2017-06-26) x86_64 GNU/Linux
.
and the axis gui shows 2.8.0 But I installed it a year ago and I am wanting to bring it up to the latest version if possible. Does that mean that I have to do a new install?

No.
If you installed using pre-compiled code you should only have to run update manager, or use synaptic or apt-get.

If you run the update manager on your computer regularly, surprise you probably already have the latest version.
(PS the latest version of Master on Buildbot is 1:2.8.0-pre1.3747.g774775cfc)

Thanks for the info

Hey
I am trying to update to 2.8 from 2.7 on wheezy. After doing the repository changes to 2.8 deb and src 2.8 deb and updating the files in synaptic when I startup linuxcnc I get a message that "This version separates the axis and the joints". To which i say "no" but then I get a errors messages that shows in the debug info

Can not find -sec EMC -var VERSION -num 1
can't read "::kins(module)": no such variable
while executing
"puts "\n$::progname: ($::kins(module) kinematics) ERROR:""
(procedure "err_exit" line 2)
invoked from within
"err_exit $emsg"
invoked from within
"if [info exists emsg] {
err_exit $emsg
}"

I am using no because before I used "yes" and when I started to jog the axis I got a stack of errors in linuxcnc and if I restarted linuxcnc again it came back up with the same error in place.

Thanks
Jim

Saying no will never work without human intervention. Master is very different.
Please post your config (after saying yes)
And please post the errors (after saying yes)

Looks like the second time was the charm. It is now running a test program and all looks good except for the X axis errors with a following error when moving a 60ipm rapid move and it happens as it come close to the end position.

Thanks for your help
