current version 2019.04.73 still missing dependencies on debian stretch

[toca-one]

Could you please eliminate the downgrade dependencies for strech?

Depends: libfontconfig1 (>= 2.11.94) but 2.11.0-6.7+b1 is to be installed
Depends: libstdc++6 (>= 7) but 6.3.0-18+deb9u1 is to be installed

Thanks

Same problem in trisquel (ubuntu xenial) libstdc++6 (>= 7)
