Comment 8 for bug 1903890

I just upgraded from Ubuntu 20.10 to Ubuntu 21.04.
Thanks to libffi7, Lutris is working again.

---

I downloaded Lutris using the instructions from https://lutris.net/downloads/

After Installation, I had issues with Lutris and received the error:

```
 Fie "/usr/lib/python3/dist-packages/OpenSSL/SSL.py", line 337, in __init__
    self.callback = _ffi.callback(

Download failed: ffi_prep_closure(): bad user_data (it seems that the version of the libffi library seen at runtime is different from the 'ffi.h' file seen at compile-time)
```

libffi7 was not available for Ubuntu 20.10.
After the upgrade to 21.04, libffi7 has been installed.
