大家好，（请考虑我在询问之前研究了错误）所以一周前我在我的 ubuntu 18 机器上安装了 youtube-dl/youtube-dlg。突然（2019 年 7 月 30 日，星期二），该程序开始表现得很奇怪。从某种意义上说，它以前从未采取过行动，这很奇怪。下载视频列表（多个视频下载）后，程序将新下载的视频重命名为underscore issue。并且它停止了其他人的下载，因为它已经“已经下载”了。我运行终端终端命令：
~youtube-dl video-url
输出是：
[youtube:user] playlist: Downloading channel page
WARNING: Unable to downloadwebpage: HTTP Error 404: Not found
[youtube:user] playlist: Downloading page #1
ERROR: Unable to download webpage: HTTP Error 404: Not Found (caused by <HTTPError 404: 'Not Found'>); please report this issue on https://yt-dl.org/bug . Make sure you are using the latest version; see https://yt-dl.org/update on how to update. Be sure to call youtube-dl with the --verbose flag and inclue its complete output.
现在详细的输出是：

我采取的下一步是在从我的机器上删除它后安装最新版本。这解决了问题的一部分。youtube-dlg 中的错误没有通过更新解决，我仍然遇到下划线重命名问题的错误。但是我可以通过终端下载但不能下载所有视频。其中一些视频显示了此错误：

这是我的实际状态，我不知道要寻找什么或在哪里寻找。感谢任何帮助。
