Commit 371221bf2f8ed19423aa2253a302c69a54c93b58 uses command to find the path of the fsck.${type} binary. This commit is part of initramfs-tools 0.121 and therefore fixed in Ubuntu 20.04 LTS "Focal Fossa".
You can still see this error message in case btrfs-progs is not installed. So please install btrfs-progs in that case. If you still experience this failure, please open a new bug report. ** Changed in: initramfs-tools (Ubuntu) Status: Confirmed => Fix Released -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to initramfs-tools in Ubuntu. https://bugs.launchpad.net/bugs/1483975 Title: update-initramfs complains about missing /sbin/fsck.btrfs Status in btrfs-tools package in Ubuntu: Fix Released Status in initramfs-tools package in Ubuntu: Fix Released Status in btrfs-tools package in Debian: Fix Released Status in initramfs-tools package in Debian: Fix Released Bug description: /sbin/fsck.btrfs moved to /bin/fsck.btrfs with btrfs-tools 4.0-2 (http://bugs.debian.org/784234), which causes $ sudo update-initramfs -u update-initramfs: Generating /boot/initrd.img-4.1.0-3-generic Warning: /sbin/fsck.btrfs doesn't exist, can't install to initramfs, ignoring. I assume this means that fsck won’t run on a btrfs /, which seems bad.
