要安裝新軟體的時候發現 /boot空間不足
無法更新…..
問題原因就是 每次更新後，沒有把舊的刪除 造成的
以下有兩種解決方是
1. 比較正規的方法 ( 參考 http://www.2eggs.org/archives/476)
在root全限下輸入下列指令
觀看有哪些Linux核心
# dpkg –get-selections | grep linux
知後會出現 許多核心名稱
linux-image–(版本號)……
保留最後一個 其他刪除
刪除指令是
#apt-get remove [名稱]
不過有時候會卡住失敗 就用第二種方法
2.直接進入 /boot 刪除 (參考 http://ju.outofmemory.cn/entry/26160)
#cd /boot
#ls
進入/boot 然後觀看檔案
機本上會有下列五種檔案
abi-3.2.0-XX-generic-pae
config-3.2.0-XX-generic-pae
initrd.img-3.2.0-XX-generic-pae
System.map-3.2.0-XX-generic-pae
vmlinuz-3.2.0-XX-generic-pae
通通使用 rm 的方式 刪除，每一種只保留最版號最大的那一個
之後 值行下列四個指令
#sudo apt-get -f install
#sudo apt-get update
#sudo apt-get upgrade
#sudo apt-get dist-upgrade
在重開機 就完成了

You must set cylinders.
You can do this from the extra functions menu.
