I can confirm that the above workaround from latchkeyed works when done in a Xubuntu persistent install to flash drive.
$ sudo su
to go to root user in terminal.
then
# mv /usr/sbin/update-initramfs /usr/sbin/update-initramfs.old
and then
# ln -s /rofs/usr/sbin/update-initramfs /usr/sbin/update-initramfs
