duplicity as of v0.7.13 requires "fasteners" module
As of v0.7.13, duplicity switched from the lockfile module (referred to in APKBUILD as py-lockfile) to the fasteners module (not present in Alpine’s repositories).
Currently in the ‘main’ repository for Alpine linux, v0.7.13.1 is
present as of commit 01497105 on August
30, 2017.
I suspect this issue may have not been visible due to the python package
installed locally in testing.
To fix this:
- py-fasteners must be created
- py-monotonic must be created (the “monotonic” module is a dependency of fasteners)
- duplicity must have it dependencies updated to drop py-lockfile and add py-monotonic
