我正在使用 Ubuntu 12.04 LTS，每当我使用时：
sudo apt-get remove
sudo apt-get install
它回复说：
cp: failed to extend `/boot/initrd.img-3.5.0-47-generic.dpkg-bak': No space left on device
dpkg: error processing initramfs-tools (--configure):
subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
initramfs-tools
E: Sub-process /usr/bin/dpkg returned an error code (1)
这是正确的吗？
正在安装/移除吗？
回复：
sudo apt-get install -f

答案1
您的错误指出：
设备上没有剩余空间
从 Dash 打开系统监视器并选择文件系统选项卡。
如果问题仅与 /boot 分区有关，请尝试以下操作：
sudo apt-get autoremove
如果不起作用，则说明 /boot 中没有空间
您有很多未使用的内核。使用以下命令删除除最后一个内核之外的所有内核：
sudo apt-get purge $(dpkg -l linux-{image,headers}-"[0-9]*" | awk '/ii/{print $2}' | grep -ve "$(uname -r | sed -r 's/-[a-z]+//')")
答案2
cp: failed to extend `/boot/initrd.img-3.5.0-47-generic.dpkg-bak': No space left on device
您必须释放该/boot分区。删除所有旧的未使用的内核。
