Restore does not work

I’m using Duplicati (Windows 10 Pro) with GPG on WebDav remote with following additional settings, everything from WebGUI.

When I click Restore, it fails with following errors:

2020-05-14 XX:XX:XX +XX - [Warning-Duplicati.Library.Compression.FileArchiveZip-BrokenCentralHeaderFallback]: Zip archive appears to have a broken Central Record Header, switching to stream mode

2020-05-14 XX:XX:XX +XX - [Error-Duplicati.Library.Main.Operation.RestoreHandler-PatchingFailed]: Failed to patch with remote file: "", message:

2020-05-14 XX:XX:XX +02 - [Error-Duplicati.Library.Main.Operation.RestoreHandler-RestoreFileFailed]: The File "D:\TEST\TEST.txt" could not be found.

However, if I use Advanced > Commandline (from WebGUI) : restore > edit as text > Run “restore” command now … It works.

Advanced options:
–gpg-encryption-switches=–cipher-algo AES256
–gpg-decryption-switches=–cipher-algo AES256

What happens on Commandline if you give a bad passphrase? I don’t run gpg, and don’t know whether that produces a decryption error, or an output file which is basically random data with a .zip extension.

One common problem in the GUI lately has been browsers and password savers autofilling bad spots…

You have attempted to change a passphrase to an existing backup, which is not supported. Please configure a new clean backup if you want to change the passphrase.

Well, I guess that idea got blocked. So do you ever have anything save passwords? I’d like to rule out:

I can’t restore from GUI with

and there are several others. In one GitHub issue, a Firefox private browsing window solved the issue, however the better long-term solution would probably be to not let any software autofill within Duplicati.

If that isn’t it, I have no other immediate theory on why your GUI Commandline works, but GUI doesn’t.

Chrome browser saved the password and that caused the issue! OMG.

To fix it, just delete all saved passwords from Chrome browser for Duplicati WebGUI.(http://localhost:8200/)

I also disabled uBlockOrigin for the page, just in case.

Thank You for the hint, @ts678 ! :slightly_smiling_face: :+1:
