我已经看到这个页面以及 ubuntu 论坛本身有很多类似的问题，但是没有任何解决方案可以帮助我，所以我也会在这里尝试：
一般问题是我的启动已满，而这一切都是因为我想更新我的 Skype（4.2。它不想连接）以及安装操作系统的最新更新而开始的。
太空情况如下：
daniel@daniel-SVS1512Z9EB:~$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/ubuntu--vg-root 909G 803G 61G 93% /
none 4,0K 0 4,0K 0% /sys/fs/cgroup
udev 3,9G 4,0K 3,9G 1% /dev
tmpfs 787M 1,2M 786M 1% /run

none 100M 36K 100M 1% /run/user
/dev/sda1 228M 226M 0 100% /boot
我读到过，228MB 通常应该足够用于 /boot 空间，而增加 /boot 空间则有点棘手。我读到的下一件事是查看我有哪些内核，如下所示：
daniel@daniel-SVS1512Z9EB:~$ ls /boot/

在其他线程中，他们继续建议删除一些旧内核，例如，我正尝试使用其中一个旧内核进行测试：
daniel@daniel-SVS1512Z9EB:~$ sudo apt-get purge linux-image-3.8.0-19
Reading package lists... Done
Building dependency tree
Reading state information... Done
Note, selecting 'linux-image-3.8.0-19-generic' for regex 'linux-image-3.8.0-19'
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
linux-image-extra-3.11.0-19-generic : Depends: linux-image-3.11.0-19-generic but it is not going to be installed
linux-image-extra-3.11.0-26-generic : Depends: linux-image-3.11.0-26-generic but it is not going to be installed
linux-image-extra-3.8.0-19-generic : Depends: linux-image-3.8.0-19-generic but it is not going to be installed
linux-image-generic : Depends: linux-image-3.11.0-26-generic but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
如果我尝试运行，apt-get-f install我会得到以下结果：
daniel@daniel-SVS1512Z9EB:~$ sudo apt-get -f install
Reading package lists... Done

The following package was automatically installed and is no longer required:
openjdk-7-jre-lib
Use 'apt-get autoremove' to remove it.
The following extra packages will be installed:
linux-image-3.11.0-19-generic linux-image-3.11.0-26-generic
Suggested packages:
fdutils linux-doc-3.11.0 linux-source-3.11.0 linux-tools
The following NEW packages will be installed:
linux-image-3.11.0-19-generic linux-image-3.11.0-26-generic

这里也说没有剩余空间。
在这种情况下，您有什么解决方案可以让我真正释放 /boot 上的一些空间吗？很抱歉说了这么久，但我只是认为提供更多信息并完成任务比提供更少信息更好。提前谢谢您！
答案1
答案2
当空间不足时，我只需删除所有通用文件的最旧版本，即，如果 N 是文件名中“通用”前面的数字：
sudo rm *N-generic
您可以对最小的数字执行此操作，直到获得足够的空间。只需小心使用该命令并确保使用正确的数字即可。
