Appendix A: Adding Non-AMD64 Support
====================================

By default, the ``setup-certlab`` script supports only AMD64 (64-bit,
x86-64) nodes. (If you created a local mirror, it includes i386/x86
binaries because they're needed by some 64-bit packages.) Beginning with
Ubuntu 20.04, direct installs in 32-bit mode to i386 computers are no
longer supported, but some i386 libraries remain available to support older
32-bit binaries running on AMD64 installations. If you expect to certify
computers of other architectures, such as ppc64el or ARM64, you must add
support for such systems in MAAS:

#. In the MAAS web UI, click the Images tab.

#. Select the Ubuntu release you want to certify in the "Ubuntu Releases"
   column.

#. Select the desired CPU types in the "Architecture" column.

#. Repeat the preceding two steps for each Ubuntu release you need to
   certify. (You can select a different set of architectures for each
   Ubuntu release.)

#. Click "Update Selection." The standard MAAS images for the new CPU
   architectures will download. This process can take several minutes, and
   perhaps over an hour on a slow Internet connection.

#. For architectures other than i386 or AMD64, you must also add support
   for extra repositories:

   #. Click the Settings tab at the top of the MAAS web UI.

   #. Click Package Repos in the navigation pane to the left of the page.

   #. If the Ubuntu Extra Architectures repository is not enabled, click
      its edit icon, ensure that Enable Repository is checked, and click
      Save Repository.

   #. For *all* the enabled repositories (including Ubuntu Extra
      Architectures), click the edit icon in the
      Actions column, ensure that all the necessary architectures are
      checked, and then click Save Repository to save the changes.

That's it. Please consult the Server Certification Team if you need
to certify systems using these CPUs.
