Budgie Installer fails with internet enabled / additional media support selected

[Sam Lane]

When installing Ubuntu-Budgie 23.10 "Mantic Minotaur" - Daily amd64 (20230920)
With internet enabled and selecting the option to "Downloand and install support for additional media formats", the installer produces a crash, and a Failed to Install message.

Steps to reproduce:
- Starting from the daily Budgie Mantic Minotaur amd64 (20230920) iso, boot the iso
- connect to a wifi network
- run the installer
- during the install, at the Applications & Updates menu:
  - Select Ubuntu Budgie Desktop (full install option)
  - check "Download and install support for additional media formats"
- selected Erase disk and Install Ubuntu Budgie
- run through rest of install options

The installer results in a Failed to Install message. When looking at the output in the installer, I can see a message:
system install failed for ['ubuntu-restricted-addons']: Unexpected error when running the command

I have attached the .crash file as well as the tarball for /var/log/installer

Hello Sam,

This is interesting. I was about to point to bug 2017278 but this seems different - because subiquity does an online install.

I was able to reproduce the issue with the latest daily.

Looking at /etc/apt in the target system, I observed that the multiverse component is disabled.

$ grep Components /etc/apt/sources.list.d/ubuntu.sources
Components: main restricted universe

which explains why ubuntu-restricted-addons could not be downloaded:

 ubuntu-restricted-addons | 29 | mantic/multiverse | source, amd64, arm64, armhf, ppc64el, riscv64, s390x

That said, there was no disabled_components set in /var/log/installer/subiquity-curtin-apt.conf.

This could indicate a bug in the deb822 sources handling by curtin.

That said, deb822 sources in curtin should be disabled (it was pushed back because of a bug in software-properties).

I think the ubuntu-budgie-installer needs to update to a more recent version of ubuntu-desktop-provision.

I have given this another go with the newest edge version of the ubuntu-budgie-installer snap. Booted with the Ubuntu Budgie beta iso (20230920).

Opened a terminal and performed a snap refresh:
ubuntu-budgie@ubuntu-budgie:~$ snap refresh ubuntu-budgie-installer --channel edge
ubuntu-budgie-installer (edge) 0+git.a38f4ea from Ubuntu budgie (ubuntubudgie) refreshed

Double-checked version with: snap list
ubuntu-budgie-installer 0+git.a38f4ea 28 latest/edge ubuntubudgie classic

Repeated the same steps, checking the box for installing the support for additional media formats.

I ran into the same installation failed message as before, with the message:
system install failed for ['ubuntu-restricted-addons']: Unexpected error when running the command

Attached are the new logs / .crash file

[Dan Bungert (dbungert)]

I agree with Olivier. Relevant work was done very recently, and I believe did not make the beta for Budgie. This should be retested after daily builds start again and after the newer ubuntu-desktop-provision is used. Thanks.

[Olivier Gayot (ogayot)]

I tested it again after snap refresh as you did Sam. Multiverse still ends up disabled on the target system.

Looking into /cdrom/casper/minimal.squashfs, multiverse is disabled there as well, so I assume it is an intended configuration on Budgie ? It likely rules out a deb822 sources bug.

With the old installer though (i.e., 22.04.3), multiverse ends up being enabled on the target system despite not being present in /cdrom/casper/filesystem.squashfs.

Is there any reason not to build the budgie ISO with multiverse enabled ? I assume rebuilding with multiverse enabled would be the simplest approach.

[fossfreedom (fossfreedom)]

Olivier - no reason that multiverse isn't enabled as far as I know. To be honest I thought it always was enabled. I presume this is a release team ask to update? I've pinged on IRC #ubuntu-release today.

[Olivier Gayot (ogayot)]

@fossfreedom Thanks for checking! Then I guess it's the right solution going forward. And #ubuntu-release feels like the best place to ask.

Best regards,
Olivier

Adding livecd-rootfs. The live installer environment is configured with multiverse enabled but /cdrom/casper/minimal.squashfs does not - so we end up:

 * failing to install ubuntu-restricted-addons
 * leaving the target system without multiverse

$ unsquashfs -dest /tmp/test /cdrom/casper/minimal.squashfs etc/apt
$ cat /tmp/test/etc/apt/sources.list
deb http://archive.ubuntu.com/ubuntu/ mantic main restricted universe
deb http://security.ubuntu.com/ubuntu/ mantic-security main restricted universe
deb http://archive.ubuntu.com/ubuntu/ mantic-updates main restricted universe

[Dan Bungert (dbungert)]

When livecd-rootfs 23.10.45 migrates, the sources.list should look like the normal template instead of the 3-line one that had no multiverse.

This bug was fixed in the package livecd-rootfs - 23.10.45
