missing targets in multitarget may only be skipped if they can be recreated

[Jose Riha]

Testcase:

$ cat /tmp/multi.json
 [
  {
   "url": "file:///tmp/fragile"
  },
  {
   "url": "file:///tmp/solid"
  }
 ]

$ duplicity --no-encryption /etc/ 'multi:///tmp/multi.json?mode=mirror'
.. backup finishes, /tmp/fragile and /tmp/solid contains the same data

# corrupt the first target

$ cat /tmp/multi.json
 [
  {
   "url": "file:///xtmp/fragile"
  },
  {
   "url": "file:///tmp/solid"
  }
 ]

$ duplicity list-current-files multi:///tmp/multi.json
Giving up after 1 attempts. OSError: [Errno 2] No such file or directory: '/xtmp/fragile

# corrupt the first target so that it can still be written to

$ cat /tmp/multi.json
 [
  {
   "url": "file:///tmp/fragile.new"
  },
  {
   "url": "file:///tmp/solid"
  }
 ]

$ duplicity list-current-files multi:///tmp/multi.json
works..

# /tmp/fragile.new is created (as empty)

Expectation:

list works even if /xtmp/fragile may not be created.

Please upgrade to the current version of duplicity. This will assure that any bugs fixed since your release are available and may fix your issue.

There are three options:

* Release tarball Install - https://launchpad.net/duplicity/+download
* Daily duplicity builds - https://launchpad.net/~duplicity-team/+archive/ubuntu/daily-dev-trunk
* Stable snap builds - “sudo snap install duplicity —classic"
* Latest snap builds - “sudo snap install duplicity —classic —edge"

NOTE: UNinstall duplicity first if it was installed via the distribution repository. For Ubuntu, that would be "sudo apt-get purge duplicity".
