Bug Description

(created from

I have been using Déjà Dup on two Ubuntu 16.04 LTS systems for quite a long time. The target for the backups is a FTP server on the same network.

This week my ISP replaced my router. After this change, backups continued to work on one of the Ubuntu systems, but on the other the backup fails immediately after I respond to the password prompt with the message "Operation failed". The password is correct, and works from the other Ubuntu system. The FTP server does not log any messages that indicate that a connection was ever received. I can ping the machine with the FTP server. On the Ubuntu system, a subdirectory is created in ~/cache/deja-dup, but nothing is written in it. I have tested with the firewall disabled on the FTP server system, but the result is the same. I have tried running deja-dup --backup from the command line with environment variable DEJA_DUP_DEBUG=1 set, but the result is the same, and no information is displayed. I haven't tried running duplicity directly, because I don't know what command line Deja Dup is sending to duplicity, and I don't want to screw up my existing backups.

I expect that I have missed a change somewhere that is resulting in this failure, but I can't find any log that would help me to identify the problem.

Any suggestions as to how I can obtain more information from Deja Dup so that I can fix my problem?

One additional observation: clicking "remember password" does not result in the password being remembered.
