Thread: Duplicity won't use PASSPHRASE env variable

hello,

i'm struggling set of scripts i've long used remote ssh-based backups using duplicity on 11.10. fresh machine installation, may not directly related 11.10, can't figure out. i'm seeing following error when try run backup via /etc/crontab:

code:

/usr/lib/python2.7/getpass.py:83: getpasswarning: can not control echo on terminal.    passwd = fallback_getpass(prompt, stream)  warning: password input may echoed.  gnupg passphrase signing key: traceback (most recent call last):    file "/usr/bin/duplicity", line 1359, in <module>      with_tempdir(main)    file "/usr/bin/duplicity", line 1342, in with_tempdir      fn()    file "/usr/bin/duplicity", line 1297, in main      globals.gpg_profile.signing_passphrase = get_passphrase(1, action, true)    file "/usr/bin/duplicity", line 154, in get_passphrase      pass1 = getpass.getpass(_("gnupg passphrase signing key:")+" ")    file "/usr/lib/python2.7/getpass.py", line 83, in unix_getpass      passwd = fallback_getpass(prompt, stream)    file "/usr/lib/python2.7/getpass.py", line 118, in fallback_getpass      return _raw_input(prompt, stream)    file "/usr/lib/python2.7/getpass.py", line 135, in _raw_input      raise eoferror  eoferror

this trying interactive password retrieve, won't work within crontab. however, script should passing in passphrase via environment:

code:

#!/bin/bash  export passphrase=xxxxxxxxxxxxxxxxxxxxxxxxxx  export home=/root    duplicity --log-file /var/log/duplicity.log --full-if-older-than 1m --include-globbing-filelist /root/bin/filelist.bkp --sign-key xxxxxxxx --ssh-options "-oprotocol=2 -oidentityfile=/root/bin/duplicity.key" / scp://xxxxx@xxxxx.org/backups/primary >> /var/log/duplicitybackup.log 2>&1    unset passphrase    echo "nightly backup successful: $(date)" >> /var/log/duplicitybackup.log  echo "nightly backup successful: $(date)" | mail -s "nightly backup successful: $(date)" xxxxx

i can't seem figure out why no longer working , why duplicity won't recognize passphrase environment variable. can offer help?

thanks,
craig

does have ideas me try or places can look?

again,
craig
