Problems uploading to ftp server

[Marijo Edlund]

Description: Ubuntu 12.10
deja-dup 24.0-0ubuntu1
duplicity 0.6.19-0ubuntu2

Im uploading my backups to a ftp server (Dlink DNS-323) and since Ubuntu 12.10 the backup hangs at uploading and nothing happens. According to the logfile of the ftp the last duplicity-inc..to..vol.difftar.gz hasnt been uploaded
the last duplicity-inc..to..vol.difftar.gz can be found on the ftp server but with size 0
it looks like it only uploads 3-4 duplicity-inc..to..vol.difftar.gz before it hangs.

I have the exact same problem on Archlinux with:

Deja-Dup 24.0
Duplicity 0.6.20

Once it hangs, if I press the "Resume Later" button and then restart the backup some more difftars are uploaded. However, at some point it hangs again. The number of difftars uploaded seems a bit arbitrary.

Update:
I have made a new clean install of ubuntu 13.04, the networkdriver are now brcmsmac.
I have changed wireless router to Technicolor Gateway TG799vn v2 10.4.0.O

Still same problem last uploaded (hanged) difftar,gz still has zero size

Questions?
why isnt there a timeout on uploading a difftar.gz to the server
Why isnt a zero sized difftar.gz when backup is removed when backup is removed

Questions 2nd try?
why isnt there a timeout on uploading a difftar.gz to the server
Why isnt a zero sized difftar.gz removed when backup is resumed

Duplicity should apparently use NcFTP for ftp transfer it doesn't because if i uninstall NcFTP i should receive "NcFTP not found: Please install NcFTP version 3.1.9 or later" but it doesn't.
According what i can read in the logfile duplixity is called with -- gio and according to documentation its forces the use of giobackend and it uses the "gvfs daemons"

[Marijo Edlund (marijoedlund)]

gvfs apparently has problems with mounting refereed link description is about Samba but it talks about lot of other things

Status changed to 'Confirmed' because the bug affects multiple users.

Official support for Ubuntu 12.10 "Quantal Quetzal" has ended. Is this issue still occurring on Ubuntu 16.10 "Yakkety Yak"?

[Michael Terry (mterry)]

I'm going to close the upstream tasks, as it seems like it was a gvfs issue in the first place and additionally likely fixed a while back.

Closing as outdated for the upstream package of Ubuntu.
