无法删除旧内核

Question

无法删除旧内核

5

我正在尝试删除旧的内核版本，以便进行升级。我使用的方法如下。

sudo apt-get purge linux-image-x.y.z-server

每次运行时都会出现以下错误：

    <(Reading database ... 516009 files and directories currently installed.)

好的，我明白的是这告诉我空间不足，这点我知道。有时候我还会收到一条消息，告诉我运行下面的内容来解决错误，但是在那时我又会收到空间不足的消息。

sudo apt-get install -f

每次我尝试都会出现现在空间错误。真是令人沮丧......谢谢大家的帮助。

这是您要求的输出，抱歉。

你的 / 或 /boot 分区的大小是多少？请附上 df -h 的输出。 - Wilf

2尝试释放启动空间，然后再试一次。 - Parto

先运行 sudo apt-get autoremove，然后再尝试删除旧内核。 - Parto

刚刚添加了autoremove和autoremove -f的结果。 - user2993692

你的boot/文件夹在你的主文件夹里吗？如果是的话，试着通过将主文件夹中的大文件移动到其他分区来释放一些空间，然后尝试运行sudo apt-get -f install命令。这样做是为了解决“设备上没有剩余空间”的错误。 - Parto

这不是在我的主文件夹里。我可以直接进入引导文件夹并删除文件吗？使用sudo rm命令？ - user2993692

我不太推荐这样做，尽管根据这位用户的说法，他就是这么做的。http://askubuntu.com/a/358860/163331 - Parto

我觉得那可能是我的问题的根源。我相信很久以前我就用这个服务器做过这件事了。这次我继续这样做是为了解决这个问题。已经浪费了一天时间在这上面了。非常感谢你的帮助！ - user2993692

我认为dpkg --force是唯一的选择。uname -r的输出是什么？ - Avinash Raj

这个命令^source：

dpkg -l linux-* | awk '/^ii/{ print $2}' | grep -v -e `uname -r | cut -f1,2 -d"-"` | grep -e [0-9] | grep -E "(image|headers)" | xargs sudo apt-get -y purge

我刚刚运行了一次，释放了723 MB的磁盘空间。这将检查您正在使用的当前内核版本，并删除其余部分。

为了避免未来出现“启动盘空间不足”错误，安装Ubuntu Tweak并使用其清理工具定期清理缓存程序、旧内核、不必要的程序等。

安装后，进入“清理工具”，在左侧边栏中选中“系统”复选框，然后在底部点击“清理”。请参考下面的图片。
