Comment 32 for bug 1833618

@Patricia,

I'll concentrate efforts into the sg3-utils issue with disco for now. For Eoan, based on the console output you attached to the bug, it seems that one of the services listed as "<email address hidden>" dependencies did not start before timeout occurred. You can check systemd output after the failure to know which one was the one to blame.

In a short list, the dependencies for getty on ttyAMA0 would be:

<email address hidden>
● ├─system-getty.slice
● └─sysinit.target
● ├─blk-availability.service
● ├─dev-hugepages.mount
● ├─dev-mqueue.mount
● ├─grub-initrd-fallback.service
● ├─keyboard-setup.service
● ├─kmod-static-nodes.service
● ├─proc-sys-fs-binfmt_misc.automount
● ├─resolvconf.service
● ├─setvtrgb.service
● ├─sys-fs-fuse-connections.mount
● ├─sys-kernel-config.mount
● ├─sys-kernel-debug.mount
● ├─systemd-ask-password-console.path
● ├─systemd-binfmt.service
● ├─systemd-hwdb-update.service
● ├─systemd-journal-flush.service
● ├─systemd-journald.service
● ├─systemd-machine-id-commit.service
● ├─systemd-modules-load.service
● ├─systemd-random-seed.service
● ├─systemd-sysctl.service
● ├─systemd-sysusers.service
● ├─systemd-tmpfiles-setup-dev.service
● ├─systemd-tmpfiles-setup.service
● ├─systemd-udev-trigger.service
● ├─systemd-udevd.service
● ├─systemd-update-utmp.service
● ├─cryptsetup.target
● ├─local-fs.target
● │ ├─-.mount
● │ ├─boot-efi.mount
● │ ├─systemd-fsck-root.service
● │ └─systemd-remount-fs.service
● └─swap.target

In a recursive list, you can see it as:

So, for now, concentrating efforts in the following output:
