Package: sddm Version: 0.18.0-1 Severity: grave Tags: upstream Justification: renders package unusable
Quoting the upstream bug report: "sddm-greeter needs execution rights at /var/lib/sddm/.cache/sddm-greeter/qmlcache/*.qmlc. krunner needs execution at /home/user/.cache/krunner/qmlcache/*.qmlc. It breaks when /var and /home partitions are mounted with noexec flag which is often used on hardened setups or Trusted Path Execution available on hardened linux kernels. As for now it could be fixed by disabling qml cache by setting QML_DISABLE_DISK_CACHE=1 environment variable. Is there a chance that qt will check permission rights first then quietly disable qmlcache per app instead of crashing? Alternatively it could create cachedir somewhere in /usr/lib/qt same as python3 have it's pycache dir." Upstream bug report: https://bugreports.qt.io/browse/QTBUG-58508 The work around of adding QML_DISABLE_DISK_CACHE=1 to /etc/enviroment got sddm working for me again. Without the work around sddm will start but show just a black screen, so I've marked this bug as grave since it completely breaks the package. -- System Information: Debian Release: bullseye/sid APT prefers testing APT policy: (500, 'testing'), (120, 'stable'), (110, 'unstable'), (100, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 5.2.0-2-amd64 (SMP w/1 CPU core) Kernel taint flags: TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_AU.UTF-8, LC_CTYPE=en_AU.UTF-8 (charmap=UTF-8), LANGUAGE=en_AU:en (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages sddm depends on: ii adduser 3.118 ii debconf [debconf-2.0] 1.5.73 ii libc6 2.28-10 ii libgcc1 1:9.2.1-4 ii libpam0g 1.3.1-5 ii libqt5core5a 5.11.3+dfsg1-4 ii libqt5dbus5 5.11.3+dfsg1-4 ii libqt5gui5 5.11.3+dfsg1-4 ii libqt5network5 5.11.3+dfsg1-4 ii libqt5qml5 5.11.3-4 ii libqt5quick5 5.11.3-4 ii libstdc++6 9.2.1-4 ii libsystemd0 242-5 ii libxcb-xkb1 1.13.1-2 ii libxcb1 1.13.1-2 ii qml-module-qtquick2 5.11.3-4 ii x11-common 1:7.7+19 ii xserver-xorg [xserver] 1:7.7+19 Versions of packages sddm recommends: ii haveged 1.9.4-2 ii libpam-systemd 242-5 ii sddm-theme-debian-elarun [sddm-theme] 0.18.0-1 ii sddm-theme-maui [sddm-theme] 0.18.0-1 Versions of packages sddm suggests: pn libpam-kwallet5 <none> pn qtvirtualkeyboard-plugin <none> -- debconf information: sddm/daemon_name: /usr/bin/sddm * shared/default-x-display-manager: sddm
