Archlinux template building instructions

These are the instructions for Qubes 3.2. They will take you step by step through the entire process start to finish

Note: These instructions have not been tested for Qubes 3.1. However they could be working.

Note: No binary package for the archlinux template exists for Qubes 3.1.

1: Create and configure VM to use for template building

  • The VM should be based on a Fedora template. It’s best to use a standalone VM. I created a standalone VM based on the Fedora 23 template. I named the VM “development”. These instructions assume a standalone VM based on a Fedora template is being used.

  • Ensure there is at least 25GB preferably 30GB of free space in the private storage. I made the private storage 30GB to be safe.

    arch-template-02

Note: Unless otherwise noted, all commands are from within the “development” VM or whatever you named your standalone VM used for building the template.

2: Create GitHub Account (optional)

  • It can be helpful. Creating only a basic account is all that is needed. This will allow you to help, going forward, with the Qubes project. You could be help edit errors in documentation. It can also be of use building other templates.

  • Create user account here https://github.com

    arch-template-03

3: Install necessary packages to ‘development’ VM for “Qubes Automated Build System”

  • Necessary packages to install:

    • git

    • createrepo

    • rpm-build

    • make

    • rpmdevtools

    • python-sh

    • dialog

    • rpm-sign

    • gnupg

  • The tools can usually be installed all together with the following terminal command string:

    • $ sudo dnf install git createrepo rpm-build make wget rpmdevtools python-sh dialog rpm-sign gnupg

      arch-template-04

4: Downloading and verifying the “Qubes Automated Build System”

  • Import the Qubes master key

    gpg --recv-keys 0xDDFA1A3E36879494
    
  • Verify its fingerprint, set as ‘trusted’. This is described here.

  • Download the Qubes developers’ keys.

    wget https://keys.qubes-os.org/keys/qubes-developers-keys.asc
    gpg --import qubes-developers-keys.asc
    
  • Download the latest stable qubes-builder repository:

    git clone git://github.com/QubesOS/qubes-builder.git qubes-builder
    

    arch-template-05

  • Copy your gpg keyrings to your local copy of the repository. (Otherwise you will be asked to download the keys again.)

    # Assuming qubes-builder is in your home directory
    cp .gnupg/pubring.gpg qubes-builder/keyrings/git/
    cp .gnupg/trustdb.gpg qubes-builder/keyrings/git/
    
  • Verify the integrity of the downloaded repository. The last line should read gpg: Good signature from

    cd qubes-builder
    git tag -v `git describe`
    

5: Configuring setup script to create builder.conf file

  • You will be creating the builder.conf file which tells where and what to use. The most automated, and in this case the easiest, way to create this is to use the script that is provided in Qubes Builder. Its named ‘setup’. Before running the script you need to edit one file it uses.

    In the future this should not be needed once a change is made to the ‘setup’ script.

    • Edit the ‘qubes-os-r3.2.conf’ which is found in /home/user/qubes-builder/example-configs Use the text editor of your choice.

      • $ cd /home/user/qubes-builder/example-config/

      • $ nano -W qubes-os-r3.2.conf or $ gedit qubes-os-r3.2.conf or etc….

        arch-template-06

      • Go to the first line containing ‘DISTS_VM ?= fc23’ it will be preceeded by line ‘DIST_DOM0 ?= fc20’. Remove ‘fc23’ or whatever is listed there leaving only ‘DISTS_VM ?=’. Then save the file and close the text editor.

        arch-template-07


6: Run the ‘setup’ script to build the builder.conf file

  • Run the ‘setup’ script located in ‘/home/user/qubes-builder/’ Make sure you are in directory ‘qubes-builder

    • $ cd /home/user/qubes-builder/

    • $ ./setup

      arch-template-08

      • First screen will ask you to import ‘Qubes-Master-Signing-key.asc’. The ‘setup’ script not only downloads but confirms the key to that of the key on Qubes-OS website.

        • Select ‘YES
        • Select ‘OK’ Press ‘Enter

          arch-template-09

      • Next screen will ask you to import Marek Marczykowski-Goracki (Qubes OS signing key). Again ‘setup’ will confirm this key to the fingerprint.

        • Select ‘YES
        • Select ‘OK’ Press ‘Enter

          arch-template-10

      • This screen will give you the choice of which Qubes Release to build the template for.

        • Select ‘Qubes Release 3.2
        • Select ‘OK’ Press ‘Enter

          arch-template-11

      • Screen “Choose Repos To Use To Build Packages

        • Select ‘QubesOS/qubes- Stable - Default Repo’
        • Select ‘OK’ Press ‘Enter

          arch-template-12

      • Screen “Build Template Only?

        • Select ‘Yes’ Press ‘Enter

          arch-template-12

      • Screen ‘Builder Plugin Selection’ will give choices of builder plugins to use for the build.

        • Deselect ‘Fedora

        • Deselect ‘mgmt_salt

        • Select ‘builder-archlinux

        • Select ‘OK’ Press Enter

          arch-template-13

      • Screen ‘Get sources’ wants to download additional packages needed for the choosen plugin/s.

        • Select ‘Yes’ Press ‘Enter

          arch-template-14

      • Then wait for download to finish and press ‘OK

        arch-template-14

      • Screen ‘Template Distribution Selection’ allows you to choose the actual template/s you wish to build.

        • Scroll Down to the very bottom (it is off the screen at first)

        • Select ‘archlinux

        • Select ‘OK’ Press ‘Enter

          arch-template-16

        Note: ‘Setup’ will close and will output the text of the created build.conf file as well as the needed make commands to build the template

        arch-template-17

7: Install all the dependencies

Note: make sure you are in the “qubes-builder” directory to run the following cmds

  • $ make install-deps

    arch-template-18

8: Get all the require sources for the build: (Note: this may take some time)

  • $ make get-sources

    arch-template-19


9: Make all the require Qubes Components

  • Note: You can run a single command to build all the Qubes components or you can run them each individually. Both ways below:

    • Single command to build all Qubes components together: (this command can take a long time to process depending of your pc proccessing power)

      • $ make qubes-vm

        arch-template-20

        • These are the indivual component ‘make’ commands:

          • $ make vmm-xen-vm

          • $ make core-vchan-xen-vm

          • $ make core-qubesdb-vm

          • $ make linux-utils-vm

          • $ make core-agent-linux-vm

          • $ make gui-common-vm

          • $ make gui-agent-linux-vm

10: Make the actual Archlinux template

  • $ make template

    arch-template-21

11: Transfer Template into Dom0

  • You need to ensure these two files are in the ‘noarch’ directory

    • $ cd /home/user/qubes-builder/qubes-src/linux-template-builder/rpm/

    • $ ls (confirm the below two files are there)

      • install-templates.sh (script to install template in dom0)
    • $ cd noarch

    • $ ls

      • qubes-template-archlinux-X.X.X-XXXXXXXXXXXX.noarch.rpm (this is the template package ‘X’ replaces version and build digits)

        arch-template-22

  • Transfer the install-templates.sh script file into Dom0 Note: as there is not a typical file transfer method for Dom0, for security reasons, this less than simple transfer function has to be used

    • Switch to Domo and open a terminal window.

    Note: Take care when entering these cmd strings. They are very long and have a number of characters that are easy to mix ‘-’ vs ‘.’ ‘Templates (correct) vs templates (wrong) or Template_‘(also wrong) This script will also take care of transfering the actual template.rpm to Dom0 as well.

    • $ qvm-run –pass-io development ‘cat /home/user/qubes-builder/qubes-src/linux-template-builder/rpm/install-templates.sh’ > install-templates.sh

    • $ chmod +x install-templates.sh

    • $ ./install-templates.sh



arch-template-23

arch-template-24

  • If everything went correct there should be a Archlinux template listed in your Qubes VM Manager *

Known problems in building with Qubes R3.X

Build fails when fetching qubes-mgmt-salt

The qubes-mgmt-salt repo is not currently forked under the marmarek user on GitHub, to whom the above instructions set the GIT_PREFIX. As Archlinux is not yet supported by mgmt-salt, simply leave it out of the build (when building the Archlinux template on it’s own) by appending the following to your override.conf file:

BUILDER_PLUGINS := $(filter-out mgmt-salt,$(BUILDER_PLUGINS))

The nm-applet (network manager icon) fails to start when archlinux is defined as a template-vm

In fact /etc/dbus-1/system.d/org.freedesktop.NetworkManager.conf does not allow a standard user to run network manager clients. To allow this, one need to change inside <policy context=”default”>:

<deny send_destination="org.freedesktop.NetworkManager"/>

to

<allow send_destination="org.freedesktop.NetworkManager"/>

DispVM, Yum proxy and most Qubes addons (thunderbird …) have not been tested at all

Error when building the gui-agent-linux with pulsecore error

module-vchan-sink.c:62:34: fatal error: pulsecore/core-error.h: No such file or directory
 #include <pulsecore/core-error.h>

This error is because Archlinux update package too quickly. Probably, a new version of pulseaudio has been released, but the qubes team has not imported the new development headers yet.

You can create fake new headers just by copying the old headers:

cd qubes-builder/qubes-src/gui-agent-linux/pulse
ls
cp -r pulsecore-#lastversion pulsecore-#archlinuxversion

You can check the current archlinux pulseaudio version like this:

sudo chroot chroot-archlinux/ pacman -Qi pulseaudio

chroot-archlinux/dev/pts has not been unmounted

This is a known problem when there are errors during building. Check what is mounted using the command mount (with no parameters). Just unmount what you can (or reboot your vm if you are too lazy :) )

Known problems in building with Qubes R2-B2

Commenting out “#define HAVE_ATTRIBUTE_FORMAT_PARSETUPLE” from chroot_archlinux/usr/include/python2.7/pyconfig.h fixes the problem, but it isn’t the right solution [1]…

A better fix is planned for the next python release (the bug is considered release blocking), and will be updated in archlinux chroot as soon as available.

[1] https://bugs.python.org/issue17547

The boot process fails without visible errors in the logs, but spawn a recovery shell

The problem is new conflict between systemd and the old sysvinit style. To fix this, you can change the master xen template in dom0 to remove sysvinit remains: Edit INSIDE DOM0 /usr/share/qubes/vm-template.conf, and change the variable ‘extra’ that contains the kernel variables: from:

extra="ro nomodeset 3 console=hvc0 rd_NO_PLYMOUTH {kernelopts}"

to:

extra="ro nomodeset console=hvc0 rd_NO_PLYMOUTH {kernelopts}"

Qubes-OS is now using different xenstore variable names, which makes to archlinux VM failing to boot

Apply the following fix in the template to revert the variable name to the old Qubes version.

You can edit the template the following way:

sudo mkdir /mnt/vm
sudo mount /var/lib/qubes/vm-templates/archlinux-x64/root.img /mnt/vm
sudo chroot /mnt/vm

Then apply the fix:

Do not forgot to unmount the VM:

umount /mnt/vm

Installing the template in dom0 fails because of a missing dependency (qubes-core-dom0-linux)

Again you built a template based on a recent Qubes API which has not been released yet. So skip the dependency for now

sudo rpm -U --nodeps yourpackage.rpm
