I'm not familiar with your SRU process, debdiff, dput, the "General Requirements" document, the "security policy document", or your upload process, and I'm not into learning about all that and filling out your special form and making your special upload when there is no guarantee that Ubuntu will actually fix the problem.
If all the info you need for your SRU process isn't already in this bug report (or in the bug report upstream linked above), I don't know what else to say. I certainly don't have the experience to answer "Where problems could occur" in a Ubuntu package management context, other than to say the obvious "people may have already written scripts that depend on the buggy behaviour". You're already running a fixed version of rsync in Kinetic, so at some level someone at Ubuntu already approved of a much more modern rsync (3.2.5 was released August 14 2022) -- please use it. I've documented the bug; someone else found the upstream fix; your Ubuntu internals of adopting the fix are more reading than I want to do. I will download the current source and update my own rsync -- I know how to do that and I know it will solve the problem for me. I hope Ubuntu solves the problem for everyone else. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to rsync in Ubuntu. https://bugs.launchpad.net/bugs/1965076 Title: rsync --update incorrectly reports file "is newer" than itself Status in rsync package in Ubuntu: Confirmed Bug description: rsync 3.2.3 has a broken "--update" option. See the examples below. The "--update" option incorrectly makes rsync say a file is newer than itself. Remove the "--update" option, and rsync correctly says the file is "uptodate". The right output should of course be "is uptodate" in all cases. This bug also shows up between machines if the source rsync is 3.1.3 and the destination is 3.2.3. The bug does not show up if the source rsync is 3.2.3 and the destination is 3.1.3. $ touch foo $ rsync -avv --update foo . delta-transmission disabled for local transfer or --whole-file foo is newer <=== THIS IS NOT CORRECT - A file can't be newer than itself. total: matches=0 hash_hits=0 false_alarms=0 data=0 sent 38 bytes received 96 bytes 268.00 bytes/sec total size is 0 speedup is 0.00 $ rsync -avv foo . delta-transmission disabled for local transfer or --whole-file foo is uptodate <=== THIS IS CORRECT total: matches=0 hash_hits=0 false_alarms=0 data=0 sent 41 bytes received 106 bytes 294.00 bytes/sec total size is 0 speedup is 0.00 ProblemType: Bug DistroRelease: Ubuntu 21.10 Package: rsync 3.2.3-4ubuntu1 ProcVersionSignature: Ubuntu 5.13.0-35.40-generic 5.13.19 Uname: Linux 5.13.0-35-generic x86_64 ApportVersion: 2.20.11-0ubuntu71 Architecture: amd64 CasperMD5CheckResult: pass CurrentDesktop: ubuntu:GNOME Date: Tue Mar 15 22:47:44 2022 InstallationDate: Installed on 2022-03-16 (0 days ago) InstallationMedia: Ubuntu 21.10 "Impish Indri" - Release amd64 (20211012) SourcePackage: rsync UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/rsync/+bug/1965076/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
