apt-get update 无法连接

apt-get update 无法连接

我在 Proxmox 4.4-1 服务器上运行 Ubuntu 16.10 Server VM。VM 的网络通过我的桥接接口 (LAN)。我的 pfSense 路由器也位于同一物理主机上,使用与 LAN 相同的桥接接口。我的 ISP 调制解调器设置为桥接模式。

每当我运行“apt-get update”时,它都会挂在“0%[连接到ca.archive.ubuntu.com(91.189.88.161)] [连接到securit”

我已经在 LAN 和 WAN 接口上完成了数据包捕获,结果显示我只发送 SYN 数据包,而没有从上面列出的 ubuntu 服务器接收到任何数据包。

我已经正确设置了 pfSense 防火墙 NAT 和规则,我正在输入此信息的笔记本电脑使用与 VM 相同的路由器并位于相同的子网/VLAN 上。

我也与我的 ISP 进行了交流,他们向我保证他们的调制解调器测试没有错误。

如果您需要更多信息,请询问。我对这个问题感到厌烦,想知道根源是什么。

谢谢!

答案1

因此我创建了以下内容: 普罗克斯莫克斯的桥梁

vmbr0 具有以下属性:

Ip Address: 10.2.0.240
Subnet Mask: 255.255.255.0
Gateway 10.2.0.1
autostart: Yes
Bridge Ports: ens33

vmbr1 具有以下属性:

autostart: yes
Bridge Ports: ens37

vmbr2 具有以下属性:

autostart: yes
Bridge Ports: ens38

由于 kvm 和 vmware 存在问题,我无法成功创建虚拟机,但我能够创建并实现 lxc 容器。激活后:1. 从 DHCP 收到 IP 地址。2. 能够成功运行命令:apt-get update

总体而言,问题可能出在防火墙规则上。不过,为了排除这个嫌疑,我建议排除虚拟机的 IP 地址,看看是否有帮助。

答案2

禁用 IPv6:

编辑您的/etc/sysctl.conf文件。

附加此内容:

net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1

运行此命令使其立即生效:

$ sudo sysctl -p

这取自这个答案

当 ISP 配置强制使用 IPv6 连接时就会出现问题。

答案3

这看起来像是某种与网络相关的配置问题。

首先,让我们回顾一下 的结果ifconfig。这些结果中要注意的是 inet 和 netmask 条目。

eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 10.2.0.220  netmask 255.0.0.0  broadcast 10.255.255.255
        inet6 fe80::226:2dff:fe46:c03b  prefixlen 64  scopeid 0x20<link>
        ether 00:26:2d:46:c0:3b  txqueuelen 1000  (Ethernet)
        RX packets 282331  bytes 209953345 (209.9 MB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 168130  bytes 106104466 (106.1 MB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

尽管有上述信息,但我的接口文件似乎存在错误。尽管我可以从网络内的机器 ping 该地址,甚至可以对其进行 ssh 访问,但网络掩码对于我的子网来说是错误的。

现在,让我们检查一下我的/etc/network/interfaces文件:

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet static
        address 10.2.0.220
        mask 255.255.255.0
        gateway 10.2.0.1
        dns-nameservers 8.8.8.8

看来我把 netmask 的条目拼错了,写成了 mask。我进行了更改,然后选择重新启动我的机器: sudo shutdown -r 0

当它重新启动时,我运行:ifconfig它提供以下内容:

eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 10.2.0.220  netmask 255.255.255.0  broadcast 10.2.0.255
        inet6 fe80::226:2dff:fe46:c03b  prefixlen 64  scopeid 0x20<link>
        ether 00:26:2d:46:c0:3b  txqueuelen 1000  (Ethernet)
        RX packets 282331  bytes 209953345 (209.9 MB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 168130  bytes 106104466 (106.1 MB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

如果您发现了类似的事情,那么此时您应该完成: sudo apt-get update

如果仍有问题,请从主机端检查虚拟机配置设置。验证网络是否已连接到网络,并且不是仅主机网络。

或者它可能与所选的镜子有关,安装时,它可能处于关闭状态,或者存在其他故障。

可以查看生成新的 sources.list: Ubuntu 源列表生成器

选择要包含的存储库和 PPA 后,单击页面底部的“生成列表”按钮。

它会为每个部分生成代码来下载并替换您当前的文件,因此在继续之前请进行备份。

curl https://repogen.simplylinux.ch/txt/yakkety/sources_SomeLongNumber.txt | sudo tee /etc/apt/sources.list

我希望这有帮助。
