Errors were encountered while processing: fuse E: Sub-process /usr/bin/dpkg returned an error code (1) Looking at the postinst code, the faulty line is udevadm test --action -p $(udevadm info -q path -n /dev/fuse) > /dev/null 2>&1 Running that yields # udevadm test --action -p /devices/virtual/misc/fuse Invalid action '-p' I'm not exactly sure what this code is supposed to achieve. Since fuse no longer ships its own udev rules, maybe it can be dropped altogether? -- System Information: Debian Release: bullseye/sid APT prefers unstable APT policy: (500, 'unstable'), (200, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.19.0-5-amd64 (SMP w/4 CPU cores) Kernel taint flags: TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8), LANGUAGE=de_DE.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages fuse depends on: ii adduser 3.118 ii libc6 2.28-10 ii libfuse2 2.9.9-1 ii mount 2.34-0.1 ii sed 4.7-1 fuse recommends no packages. fuse suggests no packages. -- Configuration Files: /etc/fuse.conf [Errno 13] Keine Berechtigung: '/etc/fuse.conf' -- no debconf information
