Hi ALex,
IIRC this was moved in Debian and it could be the breaks/conflicts they added don't apply correctly for all our upgrade paths. I'll take a look - thanks you the the report!

Oh yeah things make sense, we were ahead at the time for some releases/versions.
The re-merge brought this in and since we effectively gained it "later" it might fail the ordering.

Upgrades from Bionic would not be affected (from 2.11) and also upgrades in Focal could by chance not trigger it. Lets add proper ordering in d/control ...

/me is sad to not have hit this in any of my many pre-checks :-/
I beg your pardon @ anyone affected

Original change in Debian:
https://salsa.debian.org/qemu-team/qemu/commit/ce43f003b6dde9404a1f519a66830916cba193c4

Bumping those versions to when we introduced the change ...

I was trying to reproduce this with upgrades from Eoan and from a bunch of older Focal containers I had around - all with qemu-system-common and qemu-utils installed before upgrade.

None of them hit the same bug. So either it is not as common to be hit as I was afraid - or I'm cursed by not seeing it but the rest of the world will. That makes testing hard, but the fix is rather straight forward and non invasive so this time once I can go as-is to resolve it for those affected asap.

For completeness I checked for similar changes since Bionic:
7e77abb9 debian/qemu_2.12+dfsg-2~5 <- ok from Bionic, ok from Eoan/Focal
ce43f003 debian/qemu-3.1+dfsg-3~3 <- This issue
2b5df4f8 debian/qemu_4.1-2~8 <- ok from Bionic, ok from Eoan/Focal

Ok, the reported issue seems to be the only one that really has a bad effect.

This bug was fixed in the package qemu - 1:4.2-1ubuntu2

---------------
qemu (1:4.2-1ubuntu2) focal; urgency=medium

  * d/control: avoid upgrade issues triggered by moving ivshmem tools after
    Debian. Fixed by by bumping the related Breaks/Replaces to the
    Version Ubuntu introduced the change (LP: #1862287)
