I get the following error when trying to run backup on my laptop running Ubuntu 18.04: enter image description here

I also get the following error when trying to ask duplicity for its version:

xyz@thinkpad:~$ deja-dup --version
deja-dup 37.0
xyz@thinkpad:~$ duplicity --version
Traceback (most recent call last):
  File "/usr/bin/duplicity", line 49, in <module>
    from duplicity import collections
ImportError: cannot import name collections

I've tried to reinstall duplicity in two ways, but neither fixes any of the two errors so I think the error must lie elsewhere:

  1. apt remove duplicity && apt install duplicity

  2. rm /usr/bin/duplicity && apt remove duplicity && apt install duplicity

Does anybody know what could cause an error like that? Any hint is much appreciated.

If you are not comfortable with using rsync (or Grsync) commands and having problems with Duplicity, then use LuckyBackup downloadable from the Ubuntu Software Center.

enter image description here

It uses the rysnc command set but in a much more user friendly fashion with the added advantage that you can try out your selections first before committing them to a final run. Not only that but you can schedule backups to make life much more simple.

I have been using this for some time now backing up various drives (including a NAS) and backups can be made to cloud based storage (such as DropBox).

  • Does not answer the question. I have the same problem. My backup archive was made in using Backup (duplicity). Changing backup methods is a useless answer.
