This is not really a programming question so it should be on superuser.

Short answer -
简答——
reboot the system.
重新启动系统。
If the system comes back up, try:
如果系统恢复正常，请尝试：
find / -mtime -3 -size +100000 -exec ls -ls {} \; | sort -n
The largest newest files will be at the bottom of the list. If you can see that the file is not part of an app- a data file for example- remove it. You need at least 5% free space on /.
最大的最新文件将位于列表底部。如果您可以看到该文件不是应用程序的一部分 - 例如数据文件 - 将其删除。/ 上至少需要 5% 的可用空间。
Long term you must add more disk space, like double or triple what you have.
从长远来看，您必须添加更多磁盘空间，例如您拥有的磁盘空间的两倍或三倍。
