Package: libguestfs0 Version: 1:1.38.3-1 Severity: normal cryptsetup is a now a transitional dummy package, which depends on various things that used to be in the package. In particular, it depends on cryptsetup-initramfs which tries to unlock encrypted disks in the initramfs, and produces a warning if there aren't any:
update-initramfs: Generating /boot/initrd.img-4.17.0-1-amd64 cryptsetup: WARNING: The initramfs image may not contain cryptsetup binaries nor crypto modules. If that's on purpose, you may want to uninstall the 'cryptsetup-initramfs' package in order to disable the cryptsetup initramfs integration and avoid this warning. I'm guessing you actually want cryptsetup-bin, which contains e.g., /sbin/cryptsetup. -- System Information: Debian Release: buster/sid APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'testing-debug'), (500, 'testing'), (200, 'unstable'), (150, 'stable'), (100, 'experimental'), (1, 'experimental-debug') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.17.0-1-amd64 (SMP w/8 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US:en_GB (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages libguestfs0 depends on: ii acl 2.2.52-3+b1 ii attr 1:2.4.47-2+b2 ii binutils 2.31.1-2 ii bsdmainutils 11.1.2+b1 ii btrfs-progs 4.17-1 ii bzip2 1.0.6-8.1 ii cpio 2.12+dfsg-6 ii cryptsetup 2:2.0.4-2 ii curl 7.60.0-2 ii dash 0.5.8-2.10 ii db-util 5.3.1 ii diffutils 1:3.6-1 ii dosfstools 4.1-2 ii e2fsprogs 1.44.3-1 ii exfat-utils 1.2.8-1 ii extlinux 3:6.03+dfsg1-2 ii fdisk 2.32.1-0.1 ii file 1:5.34-2 ii gawk 1:4.1.4+dfsg-1+b1 ii gdisk 1.0.3-1+b1 ii genisoimage 9:1.1.11-3+b2 ii grub2-common 2.02+dfsg1-5 ii icoutils 0.32.3-1 ii iproute2 4.17.0-2 ii isc-dhcp-client 4.3.5-4+b1 ii kmod 25-1 ii ldmtool 0.2.4-1 ii less 487-0.1+b1 ii libacl1 2.2.52-3+b1 ii libaugeas0 1.10.1-2 ii libc6 2.27-5 ii libcap2 1:2.25-1.2 ii libfuse2 2.9.8-2 ii libhivex0 1.3.15-1+b2 ii libpcre3 2:8.39-11 ii libselinux1 2.8-1+b1 ii libsystemd0 239-7 ii libtinfo6 6.1+20180714-1 ii libtsk13 4.6.1-1 ii libvirt0 4.6.0-1 ii libxml2 2.9.4+dfsg1-7+b1 ii libyajl2 2.1.0-2+b3 ii libyara3 3.8.0-5 ii lsscsi 0.28-0.1 ii lvm2 2.02.176-4.1 ii lzop 1.03-4+b1 ii mdadm 4.1~rc1-4 ii mtools 4.0.18-2.1 ii netpbm 2:10.0-15.3+b2 ii ntfs-3g 1:2017.3.23-2 ii openssh-client 1:7.7p1-3 ii osinfo-db 0.20180628-1 ii parted 3.2-21+b1 ii procps 2:3.3.15-2 ii psmisc 23.1-1+b1 ii qemu-system-x86 1:2.12+dfsg-3 ii qemu-utils 1:2.12+dfsg-3 ii scrub 2.6.1-1+b1 ii sgabios 0.0~svn8-4 ii sleuthkit 4.6.1-1 ii squashfs-tools 1:4.3-6 ii supermin 5.1.19-2+b1 ii syslinux 3:6.03+dfsg1-2 ii systemd-sysv 239-7 ii udev 239-7 ii util-linux 2.32.1-0.1 ii xz-utils 5.2.2-1.3 ii zerofree 1.1.1-1 Versions of packages libguestfs0 recommends: ii libguestfs-hfsplus 1:1.38.3-1 ii libguestfs-reiserfs 1:1.38.3-1 ii libguestfs-xfs 1:1.38.3-1 Versions of packages libguestfs0 suggests: ii libguestfs-gfs2 1:1.38.3-1 ii libguestfs-jfs 1:1.38.3-1 ii libguestfs-nilfs 1:1.38.3-1 pn libguestfs-rescue <none> pn libguestfs-rsync <none> pn libguestfs-zfs <none> -- no debconf information
