Refusing to remove an unqualified or modified Nasiko executa

Error message

Refusing to remove an unqualified or modified Nasiko executable.

What it means

The uninstall safety check inspected the existing executable at the destination and it is either unqualified (not an ECC-pinned release) or its digest no longer matches the receipt. The uninstaller only removes binaries it can prove it installed and that have not been modified since.
