No thunderbird package in Fedora 44

I just realized that Thunderbird is no longer preinstalled in the f44 template. Of course I can just sudo dnf install thunderbird, but I am wondering:

  • Is there any reason for removing it from the default installation?
  • How could one easily check the packages that a Qubes template comes with? I tried reading GitHub - QubesOS/qubes-builderv2: Next generation of Qubes OS builder · GitHub but the build process is quite complex for someone that has no experience with it. I can’t easily find if there’s such a thing as a list of packages to be included in the template.

This is due to better aligning with Fedora defaults. Fedora ships Claws Mail as the main client in its Xfce spin.

And this is exactly the case where in-place upgrade might be preferred way to switch to a new version.

I wouldn’t necessarily say so. I’ve seen cases (not specifically on Qubes) where in-place upgrades have deleted software that had completely been removed from the repos.

For example, a while ago Kali had removed KeePassXC from its repos (it is now back).

Such things can always happen. I think it is important to see a new template version as an upgrade that needs to be checked and not as a blind drop-in replacement, no matter the way that you create these new versions.

I agree. Many things can happen. My comment was more in the context of an in-place upgrade after checking, and specifically Fedora, specifically on Qubes, specifically Thunderbird, because me personally have been through it when f44 is, and especially when I customize my templates starting from the minimal templates anyway.

EDIT: To provide the opposite example - it did happen to me with Signal template where it is even still not available for f44 in the repos when I was in-place upgrading to it, so I had to provide it the other way. That’s why I said might be in previous post.
