LinuxCNC buildbot

Welcome to the LinuxCNC buildbot!

All branches of LinuxCNC are available here as precompiled packages:

The master branch, currently 2.9 containing the latest development version. This branch is not always stable! Use with care! And if it breaks, please let us know. If you want to help test the upcoming next stable version of LinuxCNC, this is the branch for you.

The 2.8 branch, containing the latest stable version. If you want a stable version of LinuxCNC with the latest proposed bug fixes, this is the branch for you. The packages here are usually not official releases. They contain newer (less tested) changes that we are planning to include in the next official stable release. We try to only make bug fixes to real problems found in the previous stable release.

The 2.7, 2.6 and 2.5 branches, containing older stable versions. These branches have been superceded by the 2.8 branch. The old branches will be kept around for a while and will receive bug fixes. All users are encouraged to upgrade to 2.8 or later.

All other branches of LinuxCNC live in the 'scratch' component of the package archive. These are considered temporary or experimental feature branches. They are of interest mainly to the developers of the branch, and their testers. Only use this if you know what you're doing!

Upgrading to a new major version

If you're upgrading from one major version to another, for example from 2.7 to 2.8, you may need to do some configuration changes! Most configuration changes should be handled automatically when you first try to run LinuxCNC after the upgrade. Further information is available here.

Using these packages

Getting the archive signing key

To use these packages on your computer, first add the buildbot archive signing key to your apt keychain by running this command in a terminal:

sudo apt-key adv --keyserver hkp://keys.openpgp.org --recv-key
    EF1B07FEE0EE663E

(Key fingerprint = 4FA2 D1ED 5B2F 38AB 01A4 AB7E EF1B 07FE E0EE 663E)

(An alternative keyserver is keyserver.ubuntu.com)

If you get an error like "GPG: keyserver receive failed: No dirmngr" then install the missing dirmngr package by entering the following in the terminal:

sudo apt-get install dirmngr

If you get an error downloading the key it may be caused by being behind a firewall or a proxy server. Retry by specifying port 80 rather than using the default port (11371):

sudo apt-key adv --keyserver hkp://keys.openpgp.org:80 --recv-key
    EF1B07FEE0EE663E

(An alternative keyserver is keyserver.ubuntu.com:80)

If you have successfully installed the key then close the terminal.

Adding the buildbot packages

From the Main Menu, open Synaptic Package Manager.

Select Search in the menu bar and do a search using linuxcnc as the search term. Right click on any installed linuxcnc results and then click Mark for Removal. When all installed results are selected click Apply on the menu bar and these packages will be removed.

Click Settings from the menu and select Repositories.

You can then either edit or delete existing LinuxCNC entries from the repositories list. You need to end up with the following set of stanzas as the only enabled references to LinuxCNC:

deb http://buildbot.linuxcnc.org/ <distro> <branch>-<type>
deb-src http://buildbot.linuxcnc.org/ <distro> <branch>-<type>

Where:

<distro> is the name of the Linux distribution e.g buster
<branch> is the LinuxCNC branch you require e.g. 2.8
<type> is the realtime type e.g.rtpreempt

So if you installed the Buster distro and wanted 2.8 branch then you would have:

deb http://buildbot.linuxcnc.org/ buster 2.8-rtpreempt
deb-src http://buildbot.linuxcnc.org/ buster 2.8-rtpreempt

When this is completed Synaptic Package Manager should do a package reload, if not do a manual Reload from the menu bar.

The newly available LinuxCNC packages should now be showing.

Installing LinuxCNC

If no LinuxCNC packages are showing, select Search in the menu bar and do a search using linuxcnc as the search term.

Right click on the LinuxCNC package you want to install and then select Mark for Installation.

You may also select the documentation if you want it installed locally and/or the linuxcnc-dev package if you intend to build new realtime components and/or alternate front-ends for linuxcnc.

When you have made all your selections, click Apply on the menu bar and the selected packages will be installed.

You will now be able to run LinuxCNC and its associated applications from either the Main Menu or a terminal.
