The Debian maintainer marked that as wontfix for apt, that should be handled by the client
"Unreadable sources.list files are an unsupported mode of operation and will not be supported in neither APT nor python-apt (which directly calls the functions from APT). Authentication data should not be stored in sources.list files, but in a netrc file. Using that, there's no need for unreadable sources.list files. If you cannot read a sources.list file, the state would be inconsistent." ** Changed in: python-apt (Ubuntu) Status: Invalid => Won't Fix ** Also affects: oneconf (Ubuntu) Importance: Undecided Status: New ** Changed in: oneconf (Ubuntu) Importance: Undecided => High ** Changed in: oneconf (Ubuntu) Status: New => Confirmed -- 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/1323586 Title: oneconf crashes if one apt list file is unreadable Status in oneconf package in Ubuntu: Confirmed Status in python-apt package in Ubuntu: Won't Fix Bug description: oneconf-service will crash if one of the files in `/etc/apt/sources.list.d` is unreadable (for example because it has been created using sudo and umask 077).
