Docker-compose unable to find packages

I was trying to follow the Windows Tutorial to install a Nextcloud development environment, and i encounted the problem that the packages couldn't be found when running the command

$ sudo docker-compose up nextcloud proxy

I was able to fix the issue by replacing 'juliushaertl' with 'juliusknorr' in the docker-compose.yml.

juliusknorr / nextcloud-docker-dev
