在尝试升级系统时,我不断收到一条消息,提示我需要释放根分区中的空间。情况如下:
Filesystem Size Used Avail Use% Mounted on
/dev/sda5 20G 16G 3.1G 84% /
对我来说,这似乎占用了很多空间,我不知道是什么。在这个问题,一个答案建议OP(除其他事项外)搜索填满磁盘的核心转储
find / -xdev -name core -ls -o -path "/lib*" -prune
。
我进行了搜索并得出以下结果。删除这些文件夹以获得一些额外空间是否安全?也许仅从这个输出无法判断……

增加系统分区而不是删除可能导致系统崩溃的未知文件怎么样?如果硬盘上有未分配空间等可用空间,请尝试将其合并到磁盘管理中的系统分区。如果其他分区中有可用空间,请缩小其中一个分区并将冗余空间添加到系统分区。
