Kubuntu 20.04：/boot磁盘大小为 500MB，但只有 7MB 可用。当我尝试从启动菜单进行修复时，它说我需要释放空间。
尝试过
sudo apt-get upgradesudo dpkg --configure -asudo apt-get updatesudo apt-get autoremovesudo apt-get cleansudo apt-get install --fix-brokensudo apt-get install -fsudo apt-get remove ––purge package_namesudo apt-get auto-remove && apt-get clean && apt-get update && apt-get upgrade
我总是得到：
