Error during the migration

[haruka-7]

Hello, During the ./run build, I have this error : ln: /usr/bin/php: File exists. I'm under Fedora and got the same on Ubuntu.

It's seems to be OK, after deleting the line && ln -s /usr/bin/php7 /usr/bin/php \ in the Dockerfile. But during the ./run init I have the error :
