Ubuntu JeOS已经被官方抛弃,无任何支持了-2014.7.10 博主留言
出现这样的问题是因为软件源不对,用默认的软件源即可解决问题,下附默认sources.list(/etc/apt/sources.list)内容:

deb http://us.archive.ubuntu.com/ubuntu/ hardy main restricted
deb http://us.archive.ubuntu.com/ubuntu/ hardy-updates main restricted
deb http://us.archive.ubuntu.com/ubuntu/ hardy universe
deb http://us.archive.ubuntu.com/ubuntu/ hardy-updates universe
deb http://us.archive.ubuntu.com/ubuntu/ hardy multiverse
deb http://us.archive.ubuntu.com/ubuntu/ hardy-updates multiverse
deb http://security.ubuntu.com/ubuntu hardy-security main restricted
deb http://security.ubuntu.com/ubuntu hardy-security universe
