Comment 30 for bug 946988

Same error here:

duplicity 0.7.01
gpg (GnuPG) 1.4.18
Ubuntu 15.04
Python 2.7.9

/usr/bin/duplicity incremental \
       # Many --excludes
        --tempdir=/tmp \
        --encrypt-key 09E5788F \
        --use-agent \
        $HOME file://${HOME}/Network/DIMHOLT/Data

eventually results in:

Copying duplicity-full-signatures.20150805T004551Z.sigtar.gpg to local cache.
Attempt 1 failed. IOError: [Errno 5] Input/output error
