/snap/subiquity/x1/usr/bin/os-prober: 4: .: cannot open /usr/share/os-prober/common.sh: No such file

Trying to install on riscv64 with https://github.com/canonical/subiquity/commit/f9ce537053d90eb6f1dc0a9d082ca0bc102edbfc
I see the following error in the logs:

/snap/subiquity/x1/usr/bin/os-prober: 4: .: cannot open /usr/share/os-prober/common.sh: No such file
Traceback (most recent call last):

This file exists:

/snap/subiquity/x1/usr/share/os-prober/common.sh

These variables are exported (amongst others):

PATH="/snap/subiquity/x1/bin:/snap/subiquity/x1/usr/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin"
PYTHON="/snap/subiquity/x1/usr/bin/python3.8"
PYTHONPATH="/snap/subiquity/x1/lib/python3.8/site-packages"
SNAP="/snap/subiquity/x1"
SNAP_ARCH="riscv64"

We have
x1/meta/snap.yaml:9: OS_PROBER_SHARE: $SNAP/usr/share

But still this does not work as expected:

/snap/subiquity/x1/usr/bin/os-prober:4
. ${OS_PROBER_SHARE:-/usr/share}/os-prober/common.sh

Plan: os-prober will not be used by default, command line option to subiquity will enable os-prober.
