This is fixed in upstream 1.0, the bug number linked is the wrong one though unfortunately.
I asked infinity about syncing this half a month ago, as it's the final release of 1.0, and fixes another important bug that is currently in vivid for example, namely other tools complaining about invalid PEP440 version numbers for python-apt, which has happened once again since the last upload to wily. ** Changed in: python-apt (Ubuntu) Status: New => Fix Committed -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to python-apt in Ubuntu. https://bugs.launchpad.net/bugs/1484470 Title: aptsources.sourceslist or softwareproperties.ppa calling out to system-image-cli erroneously Status in python-apt package in Ubuntu: Fix Committed Bug description: daniel@daydream:~$ sudo add-apt-repository ppa:snappy-dev/snapcraft-daily usage: system-image-cli [-h] [--version] [-C DIRECTORY] [-b BUILD] [-c CHANNEL] [-d DEVICE] [-f FILTER] [-g] [--no-reboot] [-i] [-n] [-v] [--progress PROGRESS] [-p PERCENTAGE] [--list-channels] [--factory-reset] [--production-reset] [--switch CHANNEL] [--show-settings] [--set KEY=VAL] [--get KEY] [--del KEY] system-image-cli: error: Configuration directory not found: /etc/system-image/config.d usage: system-image-cli [-h] [--version] [-C DIRECTORY] [-b BUILD] [-c CHANNEL] [-d DEVICE] [-f FILTER] [-g] [--no-reboot] [-i] [-n] [-v] [--progress PROGRESS] [-p PERCENTAGE] [--list-channels] [--factory-reset] [--production-reset] [--switch CHANNEL] [--show-settings] [--set KEY=VAL] [--get KEY] [--del KEY] system-image-cli: error: Configuration directory not found: /etc/system-image/config.d usage: system-image-cli [-h] [--version] [-C DIRECTORY] [-b BUILD] [-c CHANNEL] [-d DEVICE] [-f FILTER] [-g] [--no-reboot] [-i] [-n] [-v] [--progress PROGRESS] [-p PERCENTAGE] [--list-channels] [--factory-reset] [--production-reset] [--switch CHANNEL] [--show-settings] [--set KEY=VAL] [--get KEY] [--del KEY] system-image-cli: error: Configuration directory not found: /etc/system-image/config.d Snapcraft daily builds, use only at your own risk!
