Announcement: Fedora 33 TemplateVMs available

[Andrew David Wong]

Dear Qubes Community,

New Fedora 33 TemplateVMs are now available for both Qubes 4.0 and 4.1.

*Important:* If you wish to use the Qubes Update widget to update a
Fedora 33 template, you must first switch [1] the `default-mgmt-dvm`
qube to a Fedora 33 template. (Alternatively, you can create a separate
management DisposableVM Template based on a Fedora 33 template for the
purpose of updating Fedora 33 templates.) This does not affect updating
internally using `dnf`.

Instructions are available for upgrading Fedora TemplateVMs [2]. We also
provide fresh Fedora 33 TemplateVM packages through the official Qubes
repositories, which you can get with the following commands (in dom0).

Standard [3] Fedora 33 TemplateVM:

$ sudo qubes-dom0-update qubes-template-fedora-33

Minimal [4] Fedora 33 TemplateVM:

$ sudo qubes-dom0-update qubes-template-fedora-33-minimal

After installing or upgrading a TemplateVM, please remember to update
[5] (see important note above) and switch all qubes that were using the
old template to use the new one [1].

*Addendum:* Fedora 33 has switched the default DNS resolver to
systemd-resolved [1]. If resolving local domains on your LAN does not
work as expected even when specifying the full name, you may wish to
disable systemd-resolved and enable NetworkManager in the TemplateVM
instead. For more on this, please see issue #6431 [2].

For a complete list of changes in Fedora 33, please see the official
Fedora 33 release notes [3], and for a more general overview, the
official Fedora 33 announcement [4].

Hi Andrew,

Disable it in sys-net's template, or in all Fedora templates?

Mike.

[Andrew David Wong]

I'm just relaying what was discussed in #6431, but my understanding is
that it would only be disabled in sys-net's template. I imagine you
could start there and see if it works as expected. If it does, there's
probably no need to disable it anywhere else.

Hi Andrew,

I found that disabling it in the AppVM template was required.

(I should have asked on the user list, sorry!)

Mike.
