[Bug 1770929] Re: Duplicity fails with UnicodeDecodeError in uexc function
For me this bug was actually triggered by another new bug in lftp caused by glibc upgate, see #1902832 which was obfuscated by this bug.

[Bug 1770929] Re: Duplicity fails with UnicodeDecodeError in uexc function
Hello all, Apologies, I missed these recent messages. For background, the error UnicodeDecodeError just means that a non-ASCII character is hitting a piece of code that was not designed to handle it. That is not surprising -- prior to the 0.8 series, very little of the code was designed for non-ASCII characters. What that means is that you may be seeing a UnicodeDecodeError even though this bug is fixed, because somewhere else in the code needs fixing. Victor Douglas (jhngalt): This is an interesting error and thank you very much for following our instructions on testing the snap and giving the relevant details. Can you please test with the latest stable duplicity snap and, if you still have a problem, report the bug in our new tracker (https://gitlab.com/duplicity/duplicity/-/issues )? Note that "snap run duplicity" does not actually do anything without arguments (even working correctly it gives: Command line error: Expected 2 args, got 0 Enter 'duplicity --help' for help screen.), but it still should not be giving an error like that. It looks as though the error was related to non-ASCII in your temporary directory name not being handled correctly. Martin Theiner (mathesubu1) and BlueT - Matthew Lien - 練喆明 (bluet) -- you are both using an old (pre 0.8 series) version of duplicity/deja dup. Please uninstall the system version (e.g. "sudo apt-get purge duplicity") and install the stable snap (e.g. "sudo snap install duplicity —classic") and test again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1770929 Title: Duplicity fails with UnicodeDecodeError in uexc function To manage notifications about this bug go to: https://bugs.launchpad.net/duplicity/+bug/1770929/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1770929] Re: Duplicity fails with UnicodeDecodeError in uexc function
Hello, in view of the above-mentioned post, it seems to me that the problem is not fully solved and therefore I will describe my findings. Today I tried to set up my small server backup to a second using duplicity package. I used some example for writing tiny script. #!/bin/bash export PASSPHRASE=some_pwd export FTP_PASSWORD=some_ftp_pwd duplicity ~/SQLBACKUP ftp://some_user@10.0.0.250/SQLBACKUP unset PASSPHRASE unset FTP_PASSWORD When I ran the script, I got the errors listed above, but a directory SQLBACKUP was created on the target server. The permissions of this directory were okay (some similar bug), so I tried to run the script a second time and the backup went without errors. Other backups were already running without errors too. In my opinion, the problem may be that it fails to create a backup directory on the target server fast enough. As a target server I used ftp server on Windows once and second ftp server on Ubuntu 18.04 and the result was always the same (physically three machines on network: one with duplicity and two ftp servers). When I prepared SQLBACKUP directory on the target server manually, the backup went without errors too. machine with duplicity: --- Ubuntu 18.04.4 LTS Python 2.7.17 duplicity 0.7.17 (from Ubuntu repository) lftp version 4.8.1 Perhaps a small loop in the depths of duplicity package, that tests whether a directory has already been created, would help :-). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1770929 Title: Duplicity fails with UnicodeDecodeError in uexc function To manage notifications about this bug go to: https://bugs.launchpad.net/duplicity/+bug/1770929/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1770929] Re: Duplicity fails with UnicodeDecodeError in uexc function
All, This should be fixed in 0.8.00, which has now been released. This is the first 0.8-series release, so expect issues and test it out on data you can afford to lose (if it comes to that). I have now packaged up this version as a snap. You can install it by typing: snap install duplicity --classic --beta Please uninstall your current version of duplicity to ensure you are using the snap instead of one from apt etc. (This will work out of the box on nearly all versions of Ubuntu. If you use a different distro and have never installed snaps before, visit this page: https://docs.snapcraft.io/installing-snapd ) This includes the latest duplicity and all dependencies wrapped up in a self-contained bundle. You should not need to install anything else for this to work (including for all backends). If you do test this, it would be very helpful if you could please comment here, even if the only feedback is that all worked as expected.

All, to clarify the current position, this is fixed in the 0.8 series, but I set out the steps to test the fix in comment #15 and was waiting on testing feedback before merging the patch back into the 0.7 series. Nobody gave me any testing feedback. It is therefore not yet fixed in the 0.7 series. It looks as though Ubuntu has separately patched this in Disco only (comment #19). So it will not work in Bionic or Xenial. We are now so close to a 0.8 release that I am inclined to wait for that and encourage affected users to move straight to that, rather than risk breaking people who are sticking to the 0.7 series. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1770929 Title: Duplicity fails with UnicodeDecodeError in uexc function To manage notifications about this bug go to: https://bugs.launchpad.net/duplicity/+bug/1770929/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1770929] Re: Duplicity fails with UnicodeDecodeError in uexc function
Thank you everybody for your bug reports and comments.
I believe that this bug is already fixed in the 0.8-series, but we have
not yet released a package for this.
The code triggering this is used when there is an exception/error
message containing a non-ASCII character (for example a filename), so
this is sometimes 'fixed' by fixing the underlying problem. This is why
some commenters say the problem went away when they resolved permissions
issues. I do not know what has changed that is causing this to break for
people it did not break for previously.
The reality is that version 0.7 and below were never actually written to
accommodate non-ASCII characters and the fact it worked at all was
largely luck. The 0.8 series does add proper support for non-ASCII, with
the internals converted to Unicode and Python 3 support.
Many thanks to Pete Zaitcev (zaitcev) in Bug #1797928 for proposing a
patch for this, which I had overlooked.
I have applied this in the branch here: lp:~aaron-
whitehouse/duplicity/07-uexc-fix
It would be helpful if you can please test to see if this fixes your problem as
follows:
1. Create a new destination directory to test with.
2. Test that duplicity fails as you have reported when using this destination.
3. Pull down a copy of the branch with the fix:
bzr branch lp:~aaron-whitehouse/duplicity/07-uexc-fix dup_patched
4. cd dup_patched/duplicity
5. run ./compilec.py
6. change directory back to wherever you were running duplicity from before
5. Test with the patched duplicity:
PYTHONPATH=[full path/]dup_patched [full path/]dup_patched/bin/duplicity [all
of your options/arguments]
Please let me know how you get on.
== Simple illustration of failure ==
A simple example triggering this bug is to create a couple of empty
directories, say "source1" and "dest".
Then try:
duplicity --exclude=bänana source1/ file://dest/
This should give a FilePrefixError (hideous in version 0.7 and much more
informative in 0.8), but instead says:
