我正在尝试更新运行 Debian Squeeze 的旧服务器。 apt-get 更新失败。输出在这里：

我的sources.list的内容在这里：
# local packages
deb file:/root debs/
deb-src file:/root debs/
# the basic archive
deb ftp://ftp.fi.debian.org/debian/ squeeze-lts main non-free contrib
deb-src ftp://ftp.fi.debian.org/debian/ squeeze-lts main non-free contrib
# the security patches
deb http://security.debian.org/ squeeze/updates main contrib non-free
deb http://backports.debian.org/debian-backports squeeze-backports main
到目前为止，我尝试的是将sources.list 中的前两个条目从squeeze 更改为squeeze-lts，因为squeeze 似乎不再存在于存储库中。
我知道 Squeeze 不再受到官方支持，我计划在不久的将来有时进行升级，但我想首先将当前安装设置为“干净”且最新的状态。

您的sources.list引用了两个file来源：
deb file:/root debs/
deb-src file:/root debs/
这些行期望目录下有本地 Debian 发行版/root/（带有子目录/root/debs/）。显然，那里的文件不再可用。
除非您在本地为自己的软件包维护一个特殊的存储库，否则您可以毫无问题地注释甚至删除这两行。不过，应该apt-get dist-upgrade可以工作。
