无法更新rkhunter

Question

今天，当我运行命令时(我每天都运行它，一切都很好)：

sudo rkhunter --update

为了检查数据库文件的更新，我每次都会收到这个错误：

[ Rootkit Hunter version 1.4.2 ]

Checking rkhunter data files...

  Checking file i18n versions                                [ Update failed ]

Please check the log file (/var/log/rkhunter.log)

所以我检查了日志文件，这是它的内容：

运行此命令时：

sudo rkhunter --versioncheck

我还得到了一个类似的错误：

[ Rootkit Hunter version 1.4.2 ]

Checking rkhunter version...
  This version  : 1.4.2
  Latest version: Download failed

为什么会这样呢？我怎么才能修好它呢？或者这不是我的结局吗？在这种情况下，我该怎么办？

对于一些项目，sourceforge.net网站暂时处于静态离线模式。

因此，什么也不做，以后再试一次;)

在检查我的日志文件之后

我试过：

sudo /usr/bin/wget  -O "/var/lib/rkhunter/tmp/rkhunter.upd.UndVYmZ4q6" http://rkhunter.sourceforge.net/1.3/mirrors.dat

有结果

现在让我们检查一下http://rkhunter.sourceforge.net/1.3/mirrors.dat
