我从安装了Dropboxhttps://www.dropbox.com/install-linux按照说明进行无头安装。但是，当我尝试运行它时，在输出列表的末尾出现了以下错误：

Dropbox isn't running!
Done!
我之前已经从 dropbox 存储库安装了 Dropbox，但我想在启动时以无头用户身份运行 dropbox，因此我删除了之前创建的 ~/.dropbox 和 ~/.dropbox-dist 。
我能做什么？最终目标是我可以在启动时将 Dropbox 作为无头守护进程运行，可能在 crontab 中的 @reboot 条目中。
提前致谢！
答案1
dropbox start
不是启动 dropbox 的正确命令，因为它需要显示，所以它可能是桌面系统上使用的命令。链接中使用的命令是
~/.dropbox-dist/dropboxd
这将启动守护进程（dropboxd 中的最后一个“d”）。
答案2
这对我有用
export DISPLAY=:0
dropbox start
