Package: grub2-common Version: 2.06-2 Followup-For: Bug #597084 X-Debbugs-Cc: witold.bary...@gmail.com
This problem shows also in very similar form in live-boot environment: Setting up linux-image-5.17.0-3-amd64 (5.17.11-1) ... /etc/kernel/postinst.d/dkms: dkms: running auto installation service for kernel 5.17.0-3-amd64:Deprecated feature: REMAKE_INITRD Deprecated feature: REMAKE_INITRD . /etc/kernel/postinst.d/initramfs-tools: I: update-initramfs is disabled (live system is running on read-only media). /etc/kernel/postinst.d/zz-update-grub: /usr/sbin/grub-probe: error: failed to get canonical path of `overlay'. run-parts: /etc/kernel/postinst.d/zz-update-grub exited with return code 1 dpkg: error processing package linux-image-5.17.0-3-amd64 (--configure): installed linux-image-5.17.0-3-amd64 package post-installation script subprocess returned error exit status 1 While the grub obviously is not used in the live-boot environment itself, due to construction of live-boot, it must be installed there. Then if the users tries to perform an upgrade of packages inside the live environment, it might trigger update of the kernel packages too, which will fail at update-grub as presented above. Would be nice to detect this chroot and live-boot enviornments, and skip update-grub. Even on live-boot environment, /boot/grub/grub.cfg does exist, and while modifying it (as it is on overlay fs), will not accomplish much (changes are not persisted to the underlying medium), upgrade should not fail.
