Comment 7 for bug 1641423

I thought I had managed to install duplicity via the terminal and solved the problem
but I am now getting:

BackendException: Could not initialise backend: No module named gi.repository

when I run the GUI

When I enter
 deja-dup
on the teminal I get

Usage:
  deja-dup [OPTION…]
  deja-dup --backup
  deja-dup --restore [FILES…]
  deja-dup --restore-missing DIRECTORY

Déjà Dup is a simple backup tool. It hides the complexity of backing up
the Right Way (encrypted, off-site, and regular) and uses duplicity as
the backend.

Help Options:
  -h, --help Show help options
  --help-all Show all help options
  --help-gtk Show GTK+ Options

Application Options:
  --version Show version
  --restore Restore given files
  --backup Immediately start a backup
  --restore-missing Restore deleted files
  --display=DISPLAY X display to use

  But anything I try after that (from the terminal) just gives me syntax error messages
eg
deja-dup (backup)
bash: syntax error near unexpected token `backup'

Im very new to linex and I havent used a command line entry sinnce abuot 1982 and then it was on ICL so im struggling a bit. Thanks for your help but I think I will just wait until its fixed.
