After entering these commands inside the container as root: # useradd -r -g archivebox -G audio,video archivebox # mkdir -p /home/archivebox/data # chown -R archivebox:archivebox /home/archivebox (FYI an "archivebox" user already existed for me too) Next do: # su archivebox And then: $ cd /data And run: $ archivebox manage createsuperuser # Another route to the same thing: You can exit the container and do this: $ sudo docker exec -it --user archivebox <containername> /bin/bash So your prompt looks like this: archivebox@<containerid>:/data$ Then run: archivebox manage createsuperuser Either way, you need to be in the "/data" folder where the index.sqlite3 resides to have this work (eventually...) Also, didn't even need to change any environment variables (e.g. USER=archivebox) in my docker-compose.yml or .env file. Restarted the container and the new login worked in the GUI. ✌
