Whonix Linux Installer - Development Discussion

Development
101

flathub packaging request:

102

Feature requests:

  • --uninstall-vms
  • --uninstall-gateway-xfce
  • --uninstall-workstation-xfce
  • --uninstall-virtualizer
  • --uninstall-all

The option names and functionality needs more thought. The overall feature request is “uninstallation support”.

Not sure about repository removal. Probably not simple to implement.
Also removing the Kicksecure repository on Kicksecure would make no sense.

103

The forum thread Kernel driver not installed motivated me to add a minor info level output to check if SecureBoot is enabled.

104

Expanding use of CI:

  • --virtualbox-only to test VirtualBox installer. That test should be very quick because it is run after the full Whonix installation.
  • --virtualbox-only --oracle-repo this might be a bit slower.

CI on Ubuntu latest:

2023-08-15T17:19:48.0572513Z usr/bin/installer-dist: line 878: url_version_domain: unbound variable

Gonna add a stopgap for that by defensibly initializing the domain name. Some help messages in some corner cases might be missing the domain name but that’s better than a unbound variable for now.

CI on Debian testing:

Version number changed to n/a. Gonna add a fix for that too.

105

CI issues resolved.

This doesn’t actually install VirtualBox from virtualbox.org if VirtualBox is already installed. And I am not sure it should.

Confusing output:

./usr/bin/installer-dist --non-interactive --virtualbox-only

Implies something is wrong but it’s complete. Working on it.

Switching from

  • distribution package virtualbox-qt to
  • virtualbox.org (Oracle) virtualbox-$version_number package

is now implemented.

107

Added:

VirtualBox Installation Result: ‘SUCCESS’

108

The installer can now switch back and forth from distribution packages to virtualbox.org packages.

This is being tested on CI.

About RPM Fusion, I don’t think it has more issues with secure boot than with Oracle Repo, I believe they have the same issues.
About trusting RPM Fusion, it is a third party repo, not from Fedora, not from Oracle, but an alternative.

Is there a preference to use RPM Fusion over Oracle for Fedora?

112

I haven’t found any arguments why RPM Fusion is better / more trustworthy than Oracle Repo (virtualbox.org repos).

As for SecureBoot support I am pretty sure that Oracle has worked on that. But also Fedora might have added signing of kernel modules nowadays similar to how Debian (since bookworm) and Ubuntu fixed this issue.

113

Many changes today.

zsh autocompletion does not work yet after the rename. [1]

Maybe zsh autocompletion cache needs to be rebuild.

Is there some command that should be run during Debian maintainer postinst script?

[1] Kicksecure ™ Linux Installer - Design Documentation chapter Naming in Kicksecure wiki

114

I don’t think it is because the name has changed, but because the shell did not load the new completion with the new script.

When installer bash-completion, the shell also has to be reloaded.

I dont know but rehash from the provided answer might be the best solution, but still, it doesn’t load new completions.

  • After installing package “some-cmd”, hash -r makes the command name completable, but its parameter completions are still missing, despite being added together with the (brew/deb/apk/…) package. The only way I can make it happen is to exit the shell and start a new session.

  • @conny Indeed neither bash nor zsh detects newly added command completions on the fly. You can run exec zsh (or exec bash as applicable) to completely reload the shell configuration, but keep the terminal and environment. Exactly what this does to your history (keep recent entries in the same order, or merge in the history from other terminals) depends on the shell configuration.

I don’t think exec bash or zsh should be done by the script because if the user $SHELL is Zsh but he is currently using Bash, this causes problem for the script to detect the current shell in use.

I run these commands manually after such changes.

Pushed small fixes to both completions and a typo in the script.

All of this is possible. About uninstallation support…

This is easy for KVM and VirtualBox

Isn’t it better to simply recommend manual steps for this case?

It is possible to be done on the script, we already remove VMs when reimporting them, but uninstallation is not something I see much around this forum. It will add some number of lines but I feel it won’t be used at all, as it is far easier for the user to open virtualbox, right click, remove, confirm than reading the help message or man page and having to run this:

dist-installer-cli --uninstall-vm --guest --interface cli \
  --delete-only gateway

While if I allow this kind of option:

dist-installer-cli --uninstall-vm whonix-gateway-xfce

Then it would need to be repeated:

dist-installer-cli --uninstall-vm whonix-gateway-xfce
dist-installer-cli --uninstall-vm whonix-workstation-xfce
dist-installer-cli --uninstall-vm whonix-gateway-cli
dist-installer-cli --uninstall-vm whonix-workstation-cli
dist-installer-cli --uninstall-vm kicksecure-xfce
dist-installer-cli --uninstall-vm kicksecure-cli

And this would break the logic of using

--interface cli|xfce
--guest whonix|kicksecure
--(delete|import)-only gateway|workstation

Should not be run by installer-dist-cli. That’s for sure. Does not belong there. Package desktop-config-dist or dist-base-files might be suitable. It could even be argued that it is a missing feature/bug in zsh upstream or in the zsh Debian package. To run such commands but that is more of a general issue and belongs to:
