Restore from Backup failed due to unknown error using Deja-dup

[Robbyx]

File to be recovered 155kb

Relevant free space:
/tmp space available: 36.7GiB free (total 52GiB)
Backup location: 291GiB free

Steps to the problem:
Via Nautilus find file to be recovered.
Start restore of file choosing the day from the drop down choice of dates. Restoring starts.
All ok until authentication is needed to run /USR/libexec/deja-dup/duplicity as super user.
I have failed to restore on 3 dates for the file.


Error message immediately after authentication:

Restore failed Unknown error:

Can I please have suggestions as to how to restore the file.
It might help if I could post a trace, but how do I turn on Trace in Backup?

/USR/libexec/deja-dup/duplicity Looks like an incorrect name.

Following your comment, I have just reinstalled Deja-dup. I still have the same fault. It is quite important for me to be able to recover the file. Any other ideas as to how to proceed?

Are you sure it wants your superuser and not the deja-dup encryption set password?
Are these system files or your user's files?

[Robbyx]

I copied the backup to another drive, but I still get Restore failed with unknown error.

(I used the correct authentication password.)

Any other solutions?

I have found this link which I have not been able to follow successfully

Here is an example:

$ LANG=C DEJA_DUP_DEBUG=1 deja-dup --restore
Unable to init server: Could not connect: Connection refused

(org.gnome.DejaDup:83356): Gtk-WARNING **: 20:10:42.611: cannot open display: DISPLAY XAUTHORITY=$XAUTHORITY DBUS_SESSION_BUS_ADDRESS=$DBUS_SESSION_BUS_ADDRESS

Am I right to assume I can restore the backed up files using duplicity?

I note man duplicity is referred to in the article

I note "man duplicity" is referred to in the article and the files are duplicity files so I am assuming that I can use the advice at

https://wiki.gnome.org/Apps/DejaDup/...tore/WorstCase

In view of the difficulty with the above solution, I propose to l proceed with the following two steps:

mkdir -p /tmp/restore
~$ duplicity --gio file:///media/backup /tmp/restore

I attach a screen shot of the backup files.

Does anyone know how to rename the "file:///media/backup" in the sample so as to extract the backup file for Monday?

Unable to init server: Could not connect: Connection refused

That probably means that the deja-dup "server" port cannot be connected. Is it running? Is there a firewall in the way?

(org.gnome.DejaDup:83356): Gtk-WARNING **: 20:10:42.611: cannot open display: DISPLAY XAUTHORITY=$XAUTHORITY DBUS_SESSION_BUS_ADDRESS=$DBUS_SESSION_BUS_ADDRESS

That's an X/Windows error plus a Gnome error.

Appears from here that some GUI problem, before DejaDup, is the issue. Is X/Windows running? Is the gnome DBus working?

I don't like GUI backup tools. They are too complicated. Have you ever been able to restore files before?

[Robbyx]

Thank you for your reply.

I have been able to restore files before.

Is X/Windows part of MS Windows? I am only using Ubuntu 20.04

How do I check if the Gnome D/Bus is running and if missing put it back?

[Robbyx]

The other part of my post dealt with restoring without the GUI.

How do I change the example "file:///media/backup" so as to recreate the file for Monday in the attachment. I ask because I do not understand which of the files shown in the attached screenshot, should be linked together for recovery. Is it purely based on the date in the name of the backup files?
