在尝试设置 cron 作业来自动删除软件包时，我遇到了apt autoremove -y命令失败的问题，现在我无法看到如何重新运行该操作。这是我尝试过的：
在 shell 中，我运行了
sudo apt autoremove它，它向我提供了要删除的“linux-aws-headers”类型包的列表。Reading package lists... Done Building dependency tree Reading state information...

apt autoremove -y代替cron 作业运行了，但没有像我预期的那样清理空间。我检查了 /usr/src/ ，所有 linux-aws-headers 内容仍然存在，但随后的运行

PATH从输出中可以看出，显然是有问题的。我在 cron 作业中设置了 PATH，但手动运行sudo apt autoremove仍然显示，0 to remove尽管磁盘空间仍在使用中。我的 apt 现在是否一团糟，我需要从 /usr/src 手动 rm ？
