G10's license identified as fsf-unlimited-no-warranty

**Background**

On [https://ubuntu.com/legal/open-source-licences?release=xenial](https://ubuntu.com/legal/open-source-licences?release=xenial) you will find dbus, and if looking closer we can see
```
dbus 1.10.6-1ubuntu3.6 main AFL-2.1,AFL-2.1,,BSD-3-clause,BSD-3-clause-generic,Expat,g10-permissive,GPL-2+,Tcl-BSDish
```

Looking (even) closer at the "g10-permissive" license on [https://changelogs.ubuntu.com/changelogs/pool/main/d/dbus/dbus_1.10.6-1ubuntu3.6/copyright](https://changelogs.ubuntu.com/changelogs/pool/main/d/dbus/dbus_1.10.6-1ubuntu3.6/copyright) we can see the license referred to as "g10-permissive":

**Problem**
Scancode (32.0.8) identifies the above license as [https://scancode-licensedb.aboutcode.org/fsf-unlimited-no-warranty.html](https://scancode-licensedb.aboutcode.org/fsf-unlimited-no-warranty.html).

However, these licenses (FSF and G10) are not (exactly) the same:
