** Description changed:
+ [ Impact ]
+
+ Cloud-init is currently broken on `do-release-upgrade` to plucky. In
+ plucky, cloud-init's packaging has been broken out into multiple binary
+ packages:
+ - cloud-init-base contains almost all of what used to be cloud-init
+ minus some dependencies that aren't needed everywhere
+ - Additional cloud-specific packages will be made that contain
+ cloud-init-base + the dependencies needed for that cloud
+ - cloud-init now depends on cloud-init-base + all extra cloud-specific
+ dependencies.
+
+ This allows the cloud-init package to be essentially identical to what
+ the cloud-init package contained before with the advantage of being
+ able to install only `cloud-init-base` on systems that don't need
+ everything required by `cloud-init`'s full dependencies.
+
+ When making this change, the following was initially added to
+ `cloud-init-base` package on plucky:
+
+ Breaks: cloud-init (<= 24.4~3+really24.3.1-0ubuntu4)
+ Replaces: cloud-init (<= 24.4~3+really24.3.1-0ubuntu4)
+
+ However, this doesn't work. Since cloud-init get's SRUed in full, the
+ version numbers will always need to increase. Furthermore, this means
+ `cloud-init-base` can potentially break and replace the version of
+ cloud-init on plucky being upgraded.
+
+ Instead, we can fix this problem by adding the following to currently
+ supported released series:
+ Provides: cloud-init-base
+
+ while adding the following to the current devel release:
+ Replaces: cloud-init (<< [version]), cloud-init-base
+
+ [ Test Plan ]
+
+ - Launch an instance and upgrade to the proposed version. Verify that after
upgrade cloud-init works without error and that no apt errors occurred.
+ - Launch an instance and do-release-upgrade to the next release. Verify that
after upgrade, cloud-init works without and that no apt errors occurred.
+
+ [ Where problems could occur ]
+
+ There could still be hidden errors that won't be unmasked until
+ upgrading to a later version of cloud-init or upgrading from a newer
+ version than specified in the "Replaces" line. However, since
+ "Replaces:" is version gated, we would still have the opportunity to fix
+ any new problem at that time.
+
+ [ Other Info ]
+
+ Adding `Replaces: cloud-init` to devel was the originally proposed
+ solution, but Julian Klode suggested the current approach.
