Here it is ! But
1. at the time being a container named gym already exist (for I used lxc-copy to create it) So I tried: $ lxc-create -n gym2 -o lxc.debug -l DEBUG -t download -- -d ubuntu -r xenial -a amd64 and to my surprise it worked. So there might have been something specific to the "gym" folder and I propose to close the ticket ! ** Attachment added: "lxc.debug" https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/1779582/+attachment/5159146/+files/lxc.debug -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1779582 Title: Unable to create unpriviledged container To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/1779582/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
