The problem seems to be in the calamares configuration. The initramfs
task is being called before the target's live-* packages have been
removed. This is specifically warned about in the calamares initramfs
module but we see the timestamps of the initramfs task are before the
live-* packages are removed:
# in the live system
root@lubuntu:/usr/lib/x86_64-linux-gnu/calamares/modules/initramfs# cat
README.md
## initramfs module
This module is specific to Debian based distros. Post installation on Debian
the initramfs needs to be updated so as to not interrupt the boot process
with a error about fsck.ext4 not being found.
## Debian specific notes
If you're using live-build to build your ISO and setup the runtime env
make sure that you purge the live-\* packages on the target system
before running this module, since live-config dpkg-diverts update-initramfs
and can cause all sorts of fun issues.
