Unicode exceptions issue

[Eugene Morozov]

Duplicity fails to report correct exception when run in non-ascii locale. For example, if python-boto dependency is not installed and I attempt any operation involving interaction with Amazon S3, it fails with non-descriptive error:
Traceback (most recent call last):
  File "/usr/bin/duplicity", line 1538, in <module>
    log.FatalError(u"%s: %s" % (e.__class__.__name__, util.uexc(e)),
  File "/usr/lib/python2.7/dist-packages/duplicity/util.py", line 76, in uexc
    return ufn(str(e))
UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-9: ordinal not in range(128)

This error can be easily fixed by replacing body of the uexc function in the utils module with the following statement:
return ufn(unicode(e).encode('utf-8'))

I'm using duplicity 0.6.23 (the code is the same in the latest version of duplicity) on Ubuntu 14.04.

This doesn't work for me, unfortunately. I got the same error.

Using
deja-dup 36.3-0ubuntu0.2
duplicity 0.7.12-1ubuntu1

same bug?

I'm still experiencing this bug.

Backup failed. I can't find any processing logs, so I'm not able to know which file caused the problem...

The dialog box shows:

Hello everyone,

there could by me more causes of this issue, but re-check and re-set the owner and rights of the backup folder helped me. Yes, this was caused by my own fault, but the deja-dup did not provide me with the "best" error message.

There are any details: https://askubuntu.com/questions/1248421/deja-dup-is-still-failing/1262326#1262326
