Boot method: virtual CD Image version: https://cdimage.debian.org/cdimage/weekly-builds/amd64/iso-cd/debian-testing-amd64-netinst.iso dated 2023-02-09 Installation date: 2023-02-19 Machine: qemu VM, virt-manager "Debian testing" profile Partitions: default guided partitioning on a 20G disk Base System Installation Checklist: [O] = OK, [E] = Error (please elaborate below), [ ] = didn't try it Initial boot: [O] Detect network card: [O] Configure network: [O] Detect media: [O] Load installer modules: [O] Clock/timezone setup: [O] User/password setup: [O] Detect hard drives: [O] Partition hard drives: [O] Install base system: [O] Install tasks: [O] Install boot loader: [O] Overall install: [E] Comments/Problems: Steps to reproduce ================== I used the graphical installer, and installed with mostly default settings (in particular the default guided partitioning with all files in one ext4 partition). Non-default settings, just in case they matter (but I'm fairly sure they don't): * en_GB instead of en_US; * an apt proxy (http://192.168.122.1:3142 to use apt-cacher-ng on my host system); * tasksel: LXDE instead of the default GNOME, and add a ssh server Expected result =============== The installed system boots. Actual result ============= Graphical installation proceeded normally (in particular #1031620 is fixed in this weekly build). However, on booting the installed system for the first time, I got this error: > /dev/vda1 has unsupported feature(s): FEATURE_C12 > e2fsck: Get a newer version of e2fsck! > > /dev/vda1: ***** WARNING: Filesystem still has errors ***** > > fsck exited with status code 12 > The root filesystem on /dev/vda1 requires a manual fsck followed by an (initramfs) prompt. Workaround ========== Reset the VM and boot with "fsck.mode=skip" added to the kernel command-line in grub. After booting like that once, upgrade e2fsprogs from version 1.46.6-1 (in bookworm) to version 1.47.0-1 (in sid). The initramfs is rebuilt and the rebuilt version can successfully fsck the filesystem. Speculation =========== I think this could be caused by debian-installer having udebs from e2fsprogs 1.47.0-1 in the installation environment, so that the version used to create the root filesystem has newer feature flags than the installed version of e2fsck can cope with (similar to #1030939 and #1031325). If that theory is correct, then I think that even if the e2fsprogs maintainer considers it to be important for mke2fs to create new filesystems with default feature flags that are unsupported by Debian 11, as a minimum mke2fs should be avoiding new feature flags until an e2fsck that supports those flags has migrated to testing. smcv
