Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 qubes-thunderbird : Depends: icedove but it is not installable
E: Unable to correct problems, you have held broken packages.

General notes:

buster doesn't have an icedove package, but has thunderbird.

The icedove dependency also means you can't install qubes-vm-recommended. So apt autoremove removes many packages, unless you marked them as manually installed.

Buster is testing: you have to accept that things are going to break. There's an icedove package in sid which will, at some point, migrate in to buster. But not yet.
It's not feasible for Qubes to support an unstable, shifting version of Debian. Sometimes it will work, sometimes not.

The icedove package in sid is not installable (after enabling sid). So I think the breakage is not temporary? but a lasting consequence of the branding change from icedove back to thunderbird.

After updating the dependency in qubes-thunderbird-xxx.deb control file from icedove to thunderbird, I'm able to install both qubes-thunderbird and qubes-vm-recommended in buster, and Thunderbird can "Open in DispVM" attachments again.
