docker.io/domjudge/domserver disappeared on Dec 11th
by Mathias Rav 19 Dec '17

Until December 11th, there was a "domjudge" user on Docker Hub hosting two images: https://hub.docker.com/r/domjudge/domserver/ https://hub.docker.com/r/domjudge/judgehost/ Since December 11th this user seems to have disappeared from the site. Does anyone know who maintained the images and why they are now gone? They have been working just fine for me. Sorry if this list is not the appropriate place for the question.

This is the solution that I found for aws ec2 servers Changing the kernel boot parameters on AWS for the official Ubuntu images is just as simple as editing /etc/default/grub.d/50-cloudimg-settings.cfg in the same way you’d usually edit /etc/default/grub. Note that you have to run ‘update-grub’ afterwards and then reboot.
