Hi everyone, I am cross-posting the discourse post https://discourse.ubuntu.com/t/new-naming-schema-proposal-for-reverted-upstream-release-versions/79589 Here is the raw markdown from the post: Picking a correct package version number can be quite complicated. The Ubuntu project documentation has a [very long page] (https://documentation.ubuntu.com/project/how-ubuntu-is-made/concepts/version-strings/) explaining probably all cases. The [Version: Undoing mistakes section] (https://documentation.ubuntu.com/project/how-ubuntu-is-made/concepts/version-strings/#version-undoing-mistakes) says: > In a very rare case where an upgrade to a new upstream version of a package caused major regression and the only way out is rolling back, the convention is to insert `+really` followed by the actual version number. Using `+really` helps undoing a mistake, but what should you do in case you have to undo a second mistake? Imagine you upgraded from `7.80+dfsg1-5` to `7.91+dfsg1-1`, but then revert back to `7.80+dfgs1` by using `7.91+dfsg1+really7.80+dfsg1-0ubuntu1`. Then you upgrade to `7.91` again using `7.91+dfsg1+really7.91+dfsg1-0ubuntu1`. Assume this was a mistake and you have to revert again. You could use `7.91+dfsg1+really7.91+dfsg1+really7.80+dfsg1-0ubuntu1`. This is a very long version number and hard to read. Today I propose to use more than one string besides `+really` to revert an upstream release version. Let's use following strings (in alphabetical order): * `+actually` * `+definitely` * `+for.sure` * `+really` * `+very.definitely` * `+very.very.definitely` * `+what.i.meant` So in case you have to revert multiple times, you can pick the next string in this list. Example: `7.91+dfsg1-1` -> `7.91+dfsg1+actually7.80+dfsg1-0ubuntu1` -> `7.91+dfsg1+definitely7.80+dfsg1-0ubuntu1` -> `7.91+dfsg1+for.sure7.80+dfsg1-0ubuntu1` -> `7.91+dfsg1+really7.80+dfsg1-0ubuntu1` and so on. Let's discuss this proposal before submitting a merge request for the Ubuntu project documentation. Which strings would you use and how many do you need? Are 7 strings enough? -- Benjamin Drung Debian & Ubuntu Developer -- ubuntu-devel mailing list ubuntu-devel@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel
