Package: release-notes Severity: minor The familiar "single-line" format for apt sources in .list files is, in theory, gradually being deprecated in favour of the deb822 format in .sources files[1]. We can expect the old format to be supported for a few releases yet - for a start as I understand it we're still generating new installs with /etc/apt/sources.list - but we ought to at least take the first step of offering examples of the preferred format.
Places that use the old format: old-stuff.dbk #old-sources "Checking your APT source-list files" upgrading.dbk throughout but especially #upgrade-process "Preparing APT source-list files" ...anywhere else?
