Registering Ubuntu 16.04 and 18.04 Clients

This section contains information about registering Salt clients running Ubuntu 16.04 LTS, 18.04 LTS operating systems.

SUSE Manager supports Ubuntu 16.04 LTS, 18.04 LTS, and 20.04 LTS clients using Salt. For information about registering Salt clients running Ubuntu 20.04, see client-configuration:clients-ubuntu.adoc.

Canonical does not endorse or support SUSE Manager.

Ubuntu is supported for Salt clients only. Traditional clients are not supported.

Bootstrapping is supported for starting Ubuntu clients and performing initial state runs such as setting repositories and performing profile updates. However, the root user on Ubuntu is disabled by default, so to use bootstrapping, you require an existing user with sudo privileges for Python.

Add Software Channels

Before you register Ubuntu clients to your SUSE Manager Server, check that you have the Ubuntu product enabled, and the required channels are fully synchronized.

The products you need for this procedure are:

Table 1. Ubuntu Products - WebUI
OS Version Product Name

Ubuntu 16.04

Ubuntu 16.04

Ubuntu 18.04

Ubuntu 18.04

Procedure: Adding Software Channels
  1. In the SUSE Manager Web UI, navigate to Admin  Setup Wizard  Products.

  2. Locate the appropriate products for your client operating system and architecture using the search bar, and check the appropriate product. This automatically checks all required channels. Click the arrow to see the complete list of related products, and ensure that any extra products you require are checked.

  3. Click Add Products and wait until the products have finished synchronizing.

The channels you need for this procedure are:

Table 2. Ubuntu Channels - CLI
OS Version Base Channel Security Channel Updates Channel

Ubuntu 16.04

ubuntu-1604-amd64-main

ubuntu-1604-amd64-security

ubuntu-1604-amd64-updates

Ubuntu 18.04

ubuntu-1804-amd64-main

ubuntu-1804-amd64-main-security

ubuntu-1804-amd64-main-updates

Procedure: Adding Software Channels at the Command Prompt
  1. At the command prompt on the SUSE Manager Server, as root, use the spacewalk-common-channels command to add the appropriate channels:

    spacewalk-common-channels \
    <base_channel_name> \
    <child_channel_name_1> \
    <child_channel_name_2> \
    ... <child_channel_name_n>
  2. Synchronize the channels:

    mgr-sync refresh --refresh-channels

The client tools channel provided by spacewalk-common-channels is sourced from Uyuni and not from SUSE.

Check Synchronization Status

Procedure: Checking Synchronization Progress
  1. In the SUSE Manager Web UI, navigate to Admin  Setup Wizard and select the Products tab. This dialog displays a completion bar for each product when they are being synchronized.

  2. Alternatively, you can navigate to Software  Manage  Channels, then click the channel associated to the repository. Navigate to the Repositories tab, then click Sync and check Sync Status.

Procedure: Checking Synchronization Progress from the Command Prompt
  1. At the command prompt on the SUSE Manager Server, as root, use the tail command to check the synchronization log file:

    tail -f /var/log/rhn/reposync/<channel-label>.log
  2. Each child channel generates its own log during the synchronization progress. You need to check all the base and child channel log files to be sure that the synchronization is complete.

Ubuntu channels can be very large. Synchronization can sometimes take several hours.

Root Access

The root user on Ubuntu is disabled by default. You can enable it by editing the sudoers file.

Procedure: Granting Root User Access
  1. On the client, edit the sudoers file:

    sudo visudo

    Grant sudo access to the user by adding this line at the end of the sudoers file. Replace <user> with the name of the user that is bootstrapping the client in the Web UI:

    <user>  ALL=NOPASSWD: /usr/bin/python, /usr/bin/python2, /usr/bin/python3

This procedure grants root access without requiring a password, which is required for registering the client. When the client is successfully installed it runs with root privileges, so the access is no longer required. We recommend that you remove the line from the sudoers file after the client has been successfully installed.

Register Clients

To register your Ubuntu clients, you need a bootstrap repository. By default, bootstrap repositories are automatically created, and regenerated daily for all synchronized products. You can manually create the bootstrap repository from the command prompt, using this command:

mgr-create-bootstrap-repo --with-custom-channels
