Hey, I am currently packaging kdepim for Debian and unfortunately test failing for many archs, because XDG_RUNTIME_DIR is pointing to non-existing path. If I understand the documentation from freedesktop  correctly, it is in the responsibility of the system to provide a valid path: "XDG_RUNTIME_DIR defines the base directory relative to which user-specific non-essential runtime files and other file objects (such as sockets, named pipes, ...) should be stored. The directory MUST be owned by the user, and he MUST be the only one having read and write access to it. Its Unix access mode MUST be 0700. The lifetime of the directory MUST be bound to the user being logged in. It MUST be created when the user first logs in and if the user fully logs out the directory MUST be removed. If the user logs in more than once he should get pointed to the same directory, and it is mandatory that the directory continues to exist from his first login to his last logout on the system, and not removed in between. Files in the directory MUST not survive reboot or a full logout/login cycle. " Currently the tests failing for kdav : QWARN : DavItemFetchJobTest::runSuccessfullTest() QStandardPaths: XDG_RUNTIME_DIR points to non-existing path '/run/user/2952', please create it with 0700 permissions. Several archs show the same behaviour: arm64, armel,armhf, i386, mips, mips64el, mipsel, ppc64el and s390x. Maybe also amd64 but as I uploaded amd64 packages and the buildds haven't build them. See  version 17.12.2-1. 17.12.2-2 has a temporally fix that creates and removes a XDG_RUNTIME_DIR in the build path . Just a site note - if I trigger the build process on a porterbox (barriere), it succeed, because the XDG_RUNTIME_DIR is not set and falls back to the default: QWARN : DavItemFetchJobTest::runSuccessfullTest() QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-hefee' hefee  https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html https://buildd.debian.org/status/fetch.php? pkg=kdav&arch=arm64&ver=17.12.2-1&stamp=1521119310&raw=0  https://buildd.debian.org/status/logs.php?pkg=kdav  https://salsa.debian.org/qt-kde-team/kde/kdav/commit/ f5b3e788c9d690a6e05846297895d665b8cf0f01
