我检查了 /tmp 的分区，它似乎已满。
>> df /tmp
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda2 23854928 23579092 0 100% /
检查所有分区得到以下结果：
>> df -i
Filesystem Inodes IUsed IFree IUse% Mounted on
tmpfs 2021460 1660 2019800 1% /run
/dev/sda2 1525920 398781 1127139 27% /

另一个命令（仅针对根目录）给出了以下内容

我使用的是 Ubuntu 22.04，不知道在哪里以及如何释放空间。我非常感谢您提供的任何帮助。
