Description Danilo de Paula 2021-09-21 15:56:12 UTC 
+++ This bug was initially created as a clone of Bug #2006363 +++

When downgrading from qemu-kvm-6 (or even 5) to qemu-kvm 4, the downgrade process fails with conflicts between files from qemu-kvm-common-4 and qemu-kvm-docs-6

This is an hypothesis, but I believe it happens because qemu-kvm-docs-6 doesn't get uninstalled when qemu-kvm-common-4 gets installed, raising a conflict.

Here's a output of the issue:

This BZ is more a check if this problem also happens with AV. Any version with -docs should face this.
