IRC 频道是 Ubuntu 社区基础设施中最重要的部分之一。然而，我见过的所有 Ubuntu 频道都托管在irc.freenode.net. 有什么意义irc.ubuntu.com? 我看到一些用户声称他们可以在那里找到...但是该服务器到底有没有使用呢？

答案2
鉴于Ubuntu IRC 频道
freenode 网络 (irc.freenode.net) 上有多个互联网中继聊天 (IRC) 频道，用于 Ubuntu 支持和开发。
寻求 Ubuntu 一般帮助或者仅仅结识其他 Ubuntu 用户的最佳地点是 #ubuntu 或众多本地语言频道之一。
Ubuntu 衍生产品有特定频道：#kubuntu、#edubuntu、#lubuntu 和 #xubuntu，以及与开发、错误、本地社区 (LoCo) 团队、可访问性和文档相关的单独频道。从当前频道列表中选择。
希望对您有所帮助。
