无法 apt-get 安装，可能是因为 iptables

Question

我在 OVH VPS 上使用 iptables，但无法访问 Ubuntu 软件包，而且我完全不知道为什么......

apt-get install package_name

说：

未找到 package_name

并且自动完成功能不可用。

但当我做一个时apt-get update，所有目的地都到达了。

我粘贴了我的 iptables 列表：

Chain INPUT (policy DROP)
target     prot opt source               destination
ACCEPT     all  --  anywhere             anywhere
ACCEPT     all  --  anywhere             anywhere             state RELATED,ESTABLISHED
ACCEPT     tcp  --  anywhere             anywhere             tcp spt:http
ACCEPT     tcp  --  anywhere             anywhere             tcp spt:domain
ACCEPT     udp  --  anywhere             anywhere             udp spt:domain

ACCEPT     icmp --  anywhere             anywhere             icmp echo-request
LOG        all  --  anywhere             anywhere             LOG level warning
DROP       all  --  anywhere             anywhere

Chain FORWARD (policy DROP)
target     prot opt source               destination

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination
ACCEPT     all  --  anywhere             anywhere
