Duplicity crashing, unicode issue

[Stefan]

Doing backups onto b2 keeps giving me errors:

test.sh -->PASSPHRASE="test" duplicity --encrypt-key example /mnt/ntfs/newsharecopy/ b2://example:example@example

root@datastore:/home/administrator/Desktop# ./test.sh

Tryed to change #!/usr/bin/env python2.7 to #!/usr/bin/env python3
 but I get
Traceback (most recent call last):
  File "/usr/local/bin/duplicity", line 55, in <module>
    from duplicity.dup_main import main
ModuleNotFoundError: No module named 'duplicity'

How did you install duplicity? 0.8.09 is running shebangs with python3 not python2.7.

[Stefan (stefan-cp)]

I tried multiple ways.
Before it was installed with apt and it was uploading fine until this error occurred.
I tried reinstalling it with apt, I tried snap, pip and pip3.
In the end I installed with pip and changed env in config file to python 2.7 to fix the no module duplicity error that I kept getting after reinstalling, but even so I couldn't continue the uploads.
Now I have started upload into the fresh b2 bucket.
If you wish to see any config files I will provide them, just let me know which,.

At this point you probably have multiple copies of duplicity installed with differing versions.

Do the commands and you should see:

$ find /usr -type f -name 'duplicity'
/usr/bin/duplicity

$ find /usr -type d -name 'duplicity*'
/usr/lib/python3/dist-packages/duplicity-0.8.09.egg-info
/usr/lib/python3/dist-packages/duplicity
/usr/share/doc/duplicity

If you see more than this, remove all of them manually, rerun to check, then reinstall using something other than pip.

There are four 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"
