I'm guessing that /tmp (on the host) either doesn't exist, or is a
symlink to a directory that doesn't get copied to the appliance, or
something along those lines.  This was fixed upstream in:

https://github.com/libguestfs/libguestfs/commit/34439a04f1921c4e5ece1077570b0f036a64c7ee

but you should be able to work around it by dropping a file into
/usr/lib/guestfs/supermin.d that contains the required symlink target
plus all parent directories.  eg. If /tmp (on the host) is a symlink
to /foo/bar/baz then you'd do something like this (as root):

echo > /usr/lib/guestfs/supermin.d/zz-tmp-fix <<EOF
/
/foo
/foo/bar
/foo/bar/baz
EOF
update-guestfs-appliance

I should note that this Ubuntu version of libguestfs is both ancient
and has a number of serious bugs, including security issues:
