debian jessie apt-get update失败（404）

我是debian新手。我只是想在我的vps上安装更新，并且 apt-get update 最终导致404错误。我google了一段时间，有些人建议更换或重新生成sources.list文件，所以我已经完成了（afaik）。

这是我目前的来源。列表：

# Debian packages for stable
deb http://mirror.0x.sg/debian/ stable main contrib
# Uncomment the deb-src line if you want 'apt-get source'
# to work with most packages.
# deb-src http://mirror.0x.sg/debian/ stable main contrib

# Security updates for stable
deb http://security.debian.org/ stable/updates main contrib

这是我的系统：

root@debbox:/etc/apt# uname -a
Linux debbox 4.8.6-x86_64-linode78 #1 SMP Tue Nov 1 14:51:21 EDT 2016 x86_64 GNU/Linux

我安装并运行netselect-apt来重建你看到的sources.list：

root@debbox:/etc/apt# apt-get install netselect-apt
... snip ...
Writing sources.list.
Done.

但apt-get更新仍然失败。不确定ftp.utexas的东西是什么来的。

root@debbox:/etc/apt# apt-get update

任何提示赞赏！

APT还可以存储存储库配置 /etc/apt/sources.list.d/。其中一个文件可能包含ftp.utexas.edu的错误行;我的猜测是，而不是 stable/all 它应该只包含 stable。
