Looking at the journal, I think the sequence of events is: - SSD fails last Friday - I log in today over ssh, start messing around - I notice that collectd is not running (since Friday), try to `sudo systemctl start collectd` - systemd tries to bring up collectd's dependency local-fs.target, which need /dev/sda1, which is the failed drive - I figure _that_ out and start editing /etc/fstab to switch the /boot/efi device to the backup on /dev/sdb1 - in the background systemd gives up on local-fs.target and starts emergency.target, which shuts down all the services (including sshd, but not killing my ssh session) and brings up an emergency shell - I finish editing /etc/fstab and do a `sudo mount /boot/efi; sudo systemctl daemon-reload; sudo systemctl start collectd` - systemd notices that local-fs.target is all fine actually and stops the emergency shell - systemd doesn't start all the services that it shut down minutes ago - I exit my ssh session by mistake
and now we have the situation where the emergency shell is stopped but its startup message remains, confusing users. (And also no systemd services are running, except for collectd, which is not very useful for getting the system back online.) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1931077 Title: emergency shell ignores all keyboard input Status in systemd package in Ubuntu: New Bug description: An SSD that held my /boot/efi partition failed, took down local-fs.target, which brought up emergency.target. I ended up with no ssh access, and a message on the local console telling me to press Enter to get a root shell, or press Ctrl-D to continue booting normally. The system did not react to either Enter or Ctrl-D. I could switch between virtual consoles (but nothing was running on them, e.g. no getty), toggle Caps Lock, or reboot with Ctrl+Alt+Del. An emergency console that doesn't accept keyboard input is not a useful emergency console.
