Hi there, I'm trying to install monetdb via the instructions on the website inside a Docker container derived from the Ubuntu 16.04.1 LTS image. I get the following error message: root@ContainerHost:/local# sudo apt-get update Ign:1 http://dev.monetdb.org/downloads/deb xenial InRelease Get:2 http://dev.monetdb.org/downloads/deb xenial Release [3878 B] Get:3 http://dev.monetdb.org/downloads/deb xenial Release.gpg [163 B] Hit:4 http://archive.ubuntu.com/ubuntu xenial InRelease Hit:5 http://archive.ubuntu.com/ubuntu xenial-updates InRelease Hit:6 http://archive.ubuntu.com/ubuntu xenial-security InRelease Fetched 4041 B in 0s (6161 B/s) Reading package lists...

They have been ignored, or old ones used instead. I did only find one reference to this in a previous discussion. The advice given was to create a bug report. Since for that I need to have an account and that I can't find an account creation link on the bugzilla page, I decided to use this mailing list. Regards and thanks a lot, Yan Grange
