Freshclam - 无法完成下载 main.cvd

Question

几周前安装 Ubuntu 18.04 后，我尝试安装 clamav，我在以前的 Kubuntu 14.10 系统中有效地使用了它。clamav 安装的第一步进展顺利，但是当我尝试使用 freshclam 命令下载签名数据库 main.cvd 时，我无法继续进行。当下载过程到达 86% 时，我总是收到错误消息“！无法从 db.it.clamav.net 下载 main.cvd”。我尝试更改镜像下载站点（.it、.fr）并将超时从 30 增加到 120，并在几天内重新运行该命令，但没有结果。这是我从终端收到的一系列消息：

谁能帮我解决问题？提前致谢。

我遇到了类似的问题：clamav-freshclam 服务正在用这些超时故障填满 /var/log/clamav/freshclam.log，当我关闭该服务并手动运行 freshclam 时，它会中途通过然后失败。我发现在配置文件 /etc/clamav/freshclam.conf 中有两个超时指令，一个名为 ConnectTimeout，另一个名为 RecieveTimeout，默认情况下都设置为 30。我将 ConnectTimeout 更改为 10（没有理由等待连接超过 10 秒）并将接收超时设置为 120（需要更多时间通过我贫血的 DSL 连接下拉定义文件），现在 Freshclam 和 clamav- freshclam 服务都能够正确更新。
