I have a related error after a fresh install of xubuntu 22.04.1 with zfs + encryption:
After doing a first "apt update" followed by an "apt install" of a package, apt and the whole X session crash and apt is broken from then on. Steps to reproduce: 1. Install (x)ubuntu 22.04.1 with zfs + encryption and boot installed system for the first time 2. apt update 3. apt install <some package> → apt and x session crash It seems that the apt install triggers systemd to unmount every zfs mount because systemd mistakenly thinks the rpool key is not loaded. It fails unmounting /var/lib or / but succeeds with /var/lib/apt, /var/lib/dpkg. This causes apt to not work anymore. I observed the following: • Somehow after the first boot of the freshly installed system, the service unit /run/systemd/generator/zfs-load-key-rpool.service is not generated by zfs-mount-generator • Because this unit must be available and active, this seems to cause systemd to think that the key for the rpool is not loaded → systemd starts unmounting all zfs mounts after some trigger Workaround: Reboot immediately after the first boot → service unit gets generated and started correctly. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to zfs-linux in Ubuntu. https://bugs.launchpad.net/bugs/1970066 Title: (Encrypted) ZFS breaks 22.04 installation Status in snapd package in Ubuntu: Confirmed Status in zfs-linux package in Ubuntu: Confirmed Status in snapd source package in Jammy: Confirmed Status in zfs-linux source package in Jammy: Confirmed Bug description: On a freshly installed 22.04.0 amd64 Desktop with (encrypted) ZFS, removing the Firefox snap breaks: * the current gnome-shell session - it returns to gdm3 login prompt * snapd - all snaps are marked 'broken' * dpkg - dpkg status database is lost Reproducible on dedicated hardware and VMs. Not reproducible on a default (/ on ext4) installation.
