求救各位大侠：boot下空间不足，导致既不能删除就内核，也不能升级新版本

求救：boot下空间不足，导致既不能删除就内核，也不能升级新版本

搞一个够大的新分区 把boot下的文件复制过去
修改启动挂载设置，把boot指到新分区

请问具体怎么弄啊，我刚学linux不会弄呢

执行以下指令将结果全部复制贴上来

进live cd 手动删除一两个旧内核

1. 先了解你的掛載分割區情況 再給你建議

2. 如果可以登入 試用桌面 把下面指令 複製 貼進終端機 執行
2-1. sudo efibootmgr -v
2-2. sudo parted -l print
2-3. sudo cat /mnt/etc/fstab # /mnt 見 2-3-1
2-3-1. 把原來掛載 / 的分割區 掛載到 /mnt
sudo mount /dev/sda1 /mnt # 請以原來掛載 / 的 分割區 取代 /dev/sda1
2-4. 把 2-1, 2-2, 2-3 結果全部直接 選取/複製/貼上來
不要摘錄 以免遺漏重要訊息
不要擷圖 方便回文直接引用你貼上來的資料 方便你閱讀

按照你的提示，我执行了命令，结果如下：

不要重新启动计算机（即保证 uname -a 汇报 4.8.0-43-generic），先执行以下指令


重新启动计算机。

鉴于您的 boot 分区只有 180M，您也可以考虑不再升级内核

按照你前面的建议，我执行了，但是有错误发生。请帮忙看看。

1. 尝试执行一次 sudo apt update 刷新软件包列表
2. 您也可以暂时移除 linux-image-generic。如果您以后不打算再更新内核，可以不再安装
(如果 1. 有效则不需要这样做。)

3. 执行以下指令将结果贴上来 看看

4. 将 /etc/apt/sources.list 的内容贴上来 看看

单独给boot一个分区是错误的

这个命令我执行了，没有出错
