For SPDX license identifiers, you can simply run 'reuse download --all' to get any missing ones. For custom licenses (starting with 'LicenseRef-'), you need to add these files yourself. * Fix invalid SPDX License Expressions: In one or more files there are SPDX License Expressions which cannot be parse. Check whether the value that follows 'SPDX-License-Identifier:' is correct. If the detected expression is not meant to be valid, put it between 'REUSE-IgnoreStart' and 'REUSE- IgnoreEnd' comments.
