Heroku 16 Not working 'GLIBC_2.25' not found (required by ffmpeg)

I receive this error message
```
ffmpeg: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.25' not found (required by ffmpeg)
ffmpeg: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.27' not found (required by ffmpeg)
ffmpeg: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.27' not found (required by ffmpeg)

What can I do?
