Public bug reported:
Upon boot of a system that uses LVM2 you get the message:
ln: /tmp/mountroot-fail-hooks.d//scripts/init-premount/lvm2: No such
file or directory
This is because the script /usr/share/initramfs-tools/scripts/init-
premount/lvm2 uses the add_mountroot_fail_hook function from /usr/share
/initramfs-tools/scripts/functions (which is sources right before), but
this function contains a bug that takes the full path of the source
script instead of the given argument as name for the target.
Version of Ubuntu: 20.04 LTS
Version of initramfs-tools: 0.136ubuntu6
For a live installation, this may be fixed with (all on one line):
sudo sed -i 's,\(ln -s "\$0" /tmp/mountroot-fail-
hooks\.d/\)"\$0",\1"\$1",' /usr/share/initramfs-tools/scripts/functions
&& sudo update-initramfs -u
and verified by checking that this message now disappears on next boot:
sudo journalctl -b | grep mountroot-fail-hooks
A proposed patch for the source distribution is attached.
** Affects: initramfs-tools (Ubuntu)
Importance: Undecided
Status: New
** Patch added: "Proposed fix"
