root@brown:/var/lib/lxc/ubuntu_lxc# lxc-start -n ubuntu_lxc
lxc-start: confile.c: parse_line: 2014 unknown key lxc.uts.name
lxc-start: parse.c: lxc_file_for_each_line: 57 Failed to parse config: lxc.uts.name = ubuntu_lxc
lxc-start: tools/lxc_start.c: main: 284 Failed to create lxc_container

The container I archived and copied the remote server is named "ubuntu_lxc", is the folder name, and is the name in the config file.

What did I miss?
