Install rhasspi in debian stretch?

Help
1

I follow this procedure below, but get stuck because debian 9 (stretch) doesn’t have libgfortran4 but only have libgfortran3. Due to limited space, I cannot also install docker version. Any suggestion?

Is it possible to upgrade to Buster? Because Debian Stretch has reached its end of life date last month. Otherwise you’ll have to install/build libgfortran4 yourself, but that will probably not be the only issue you face, so is it worth your time?

I have old hardware system and have too many functions running on that system. It will take huge efforts to port everything to buster. I think I will expand storage in the system and go for docker installation if too troublesome to run on debian stretch

I see. Yes, the Docker installation will be easier in that case.
