Package: snapd Version: 2.71-3 Severity: important File: /usr/bin/snap X-Debbugs-Cc: [email protected]
Dear Maintainer, What led up to the situation? I tried to install a snap on Debian 13, and snapd’s syscheck failed because a test mount succeeded but the canary file couldn’t be read. What exactly did you do (or not do) that was effective (or ineffective)? I manually created and mounted a squashfs image, which worked fine, showing the issue is specific to snapd’s internal mount test. I also verified AppArmor, cgroups, and user namespace support, all of which appeared correct. What was the outcome of this action? Snapd reported no error on the mount, but the canary file was unreadable, causing snap installations to fail. What outcome did you expect instead? I expected snapd’s syscheck to succeed, allowing snaps to install normally, as manual squashfs mounts work without issue. Output after the command "snap install hello-world": error: system does not fully support snapd: squashfs mount returned no err but canary file cannot be read -- System Information: Debian Release: 13.2 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable-security'), (500, 'testing'), (500, 'stable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 6.12.48+deb13-amd64 (SMP w/6 CPU threads; PREEMPT) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages snapd depends on: ii adduser 3.152 ii apparmor 4.1.0-1 ii ca-certificates 20250419 ii dbus-user-session [default-dbus-session-bus] 1.16.2-2 ii dbus-x11 [dbus-session-bus] 1.16.2-2 ii gnupg 2.4.7-21 ii init-system-helpers 1.69~deb13u1 ii kmod 34.2-2 ii libapparmor1 4.1.0-1 ii libc6 2.41-12 ii libcap2 1:2.75-10+b1 ii libcap2-bin 1:2.75-10+b1 ii libseccomp2 2.6.0-2 ii libudev1 257.9-1~deb13u1 ii openssh-client 1:10.0p1-7 ii squashfs-tools 1:4.6.1-1 ii systemd 257.9-1~deb13u1 ii udev 257.9-1~deb13u1 Versions of packages snapd recommends: ii gnupg 2.4.7-21 Versions of packages snapd suggests: ii kdialog 4:25.04.0-1 ii zenity 4.1.90-1 -- no debconf information
