Status: New => Triaged
** Changed in: qemu (Ubuntu Saucy)
Importance: Undecided => High
** Description changed:
+ =====================
+ SRU Justification
+ 1. Impact: cloud archive users cannot upgrade cleanly
+ 2. Development fix: properly mark qemu-utils as replacing qemu-kvm to force
conflicting files to be replaced.
+ 3. Stable fix: same as development fix
+ 4. Test case: see below. (basically, install grizzly cloud archive on
precise; then upgrade to havana)
+ 5. Regression potential: we are only marking qemu-utils as conflict/replacing
old qemu-kvm, so there should be no regressions.
+ =======================
+
When upgrading from the grizzly qemu packages to the havana packages
(1.0+noroms-0ubuntu14.11 to 1.5.0+dfsg-3ubuntu5~cloud0), initial package
configuration fails:
