Please upgrade to the current version of duplicity. If you can reliably reproduce this bug, please let me know what you did, in detail, with attached -v9 log files and minimal munging. DO NOT copy/paste log files here. They are impossible to read. I took the script in the bug description section, modified it to use verify instead of the check kludge, and have been unable to reproduce it after many runs. It still fails to verify this bug. There are multiple options both stable and latest: - Stable snap builds - “sudo snap install duplicity —classic" - Latest snap builds - “sudo snap install duplicity —classic —edge" - Stable pip3 builds - “sudo pip3 install duplicity" - Latest pip3 builds - “sudo pip3 install --pre duplicity" - Stable duplicity PPA - https://code.launchpad.net/~duplicity-team/+archive/ubuntu/duplicity-release-git - Latest duplicity PPA - https://code.launchpad.net/~duplicity-team/+archive/ubuntu/duplicity-develop-git - Stable tarball install - https://launchpad.net/duplicity/+download - Source - https://gitlab.com/duplicity/duplicity Note 1: UNINSTALL duplicity first if it was installed from a different source.. This is due to divergent install locations, especially between repository installs and the other forms. Note 2: Launchpad PPAs contain builds for Bionic 18.04, Eoan 19.10, Focal 20.04, Hirsute 20.10 and Impish 21.04. Note 3: Xenial 16.04 works with Snap and Pip installs, but cannot be built under Launchpad PPAs at the moment. ** Changed in: duplicity Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/487720 Title: Restore fails with "Invalid data - SHA1 hash mismatch" To manage notifications about this bug go to: https://bugs.launchpad.net/deja-dup/+bug/487720/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 487720] Re: Restore fails with "Invalid data - SHA1 hash mismatch"
I need to find a reproducible scenario. There are hardware reasons for network transfers to drop bits and there are software reasons for the problem. I think we are seeing a mix of both. I've had downloads fail when going through a non-parity checking router, so that's one for hardware. I've yet to reproduce it in a reliable scenario with just software. ** Changed in: duplicity Importance: Medium => High ** Changed in: duplicity Status: Fix Released => Confirmed ** Changed in: duplicity Milestone: 0.6.14 => None ** Changed in: duplicity Assignee: (unassigned) => Kenneth Loafman (kenneth-loafman) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/487720 Title: Restore fails with "Invalid data - SHA1 hash mismatch" To manage notifications about this bug go to: https://bugs.launchpad.net/deja-dup/+bug/487720/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 487720] Re: Restore fails with Invalid data - SHA1 hash mismatch
I ran into the same problem. duplicity version 0.6.15 (might have been 0.6.14 when doing the backup). I used backintime for years until december 2011, found deja dup, and deleted the plain backup after a successful backup with deja dup. What a mistake. After an update the system broke and was not bootable. No problem, as i assumed the backup was there. I ran into the SHA1 mismatch issue. I have 699 .difftar.pgp files out of which 7 could not be processed with duplicity. I tried out the instructions from https://live.gnome.org/DejaDup/Help/Restore/WorstCase (Thanks for those MichaelTerry!) and was relieved when I saw the folders reappearing. Micheal's instructions take you to the point where the files are spread onto two folders multivol_snapshot and snapshot , the first one containing one folder per file, which then contains 64kb parts of the actual file. As I wanted to restore as much - and as good - as possible, I looked for scripts that do the 'cat' automatically . I found 2 or 3 scipts, and I tested the one from here https://gist.github.com/1365425 on the 70GB of original data. One run takes several hours. It creates the files, but something goes wrong. Lets say an Image was spread on 4 blocks. If I want to view that image, half of it looks ok, the rest ist missing. Or the image looks picassofied. Funny, at times if *it just wasn't the only backup of past 10 years* This person describes a similar behavior. https://bugs.launchpad.net/duplicity/+bug/713832/comments/1 I don't mind loosing business docs, even if not all of them are in the companies data centre. I don't mind loosing many hundreds of source code files, I am sure I can redo that. But the pictures? So obviously the question is: Is there a chance to reassemble the blocks in a way that the resulting jpeg files are not corrupted? Or alternatively: Does anyone know a data curation solution that detects such corruptions? Possibly the data is present, at least for 70,80,(95?) % and it is the recombining of the blocks that creates the problem. Truly, any help and hints appreciated. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/487720 Title: Restore fails with Invalid data - SHA1 hash mismatch To manage notifications about this bug go to: https://bugs.launchpad.net/deja-dup/+bug/487720/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 487720] Re: Restore fails with Invalid data - SHA1 hash mismatch
I thought I'd write a little HOWTO on recovering from this bug, in case people hit it from using versions that aren't fixed. It won't be able to restore all original files, but you can restore most. The central issue is that one or several of the backup volumes will be corrupted and likely not the correct size. So the first step is to identify which ones. The second step will be to restore everything *but* the files that are supposed to be in that volume. Step 1: Identify corrupted volumes A) Find your manifest file. If you did not encrypt your backup, it will end in .manifest. If you did, it will end in .manifest.gpg and you will first have to run gpg --decrypt MANIFESTFILE to decrypt it. B) Search for the provided Manifest hash in the error message. It will be a string like 11cd330357618de52e4e5361a6e63b09ee951ae2. This will show you which volume is corrupted. C) In this same volume block, you can see StartingPath and EndPath. This is the range of files that are supposed to be in that volume. You won't be able to get these back. :-/ Step 2: Restoring all other files D) Using Deja Dup, you can restore many files at once by using either the lost files method [1] or the revert files method [2]. Make sure you avoid trying to restore any file that you found to be inside a corrupted volume.
