如发布中所述笔记。Zesty 将获得 9 个月的支持，直到 2018 年 1 月。因此，您可以使用old-releases站点来安装 zesty 包。
您可以使用以下来源列表条目：
deb http://old-releases.ubuntu.com/ubuntu/ zesty main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ zesty-updates main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ zesty-security main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ zesty-proposed main restricted universe multiverse
deb http://old-releases.ubuntu.com/ubuntu/ zesty-backports main restricted universe multiverse
# this repo is disabled!
#deb http://archive.canonical.com/ubuntu zesty partner
deb-src http://old-releases.ubuntu.com/ubuntu/ zesty main restricted universe multiverse
deb-src http://old-releases.ubuntu.com/ubuntu/ zesty-updates main restricted universe multiverse
deb-src http://old-releases.ubuntu.com/ubuntu/ zesty-security main restricted universe multiverse
可以通过 apt 成功检索，没有任何问题。
