由于我通常能够在google的帮助下解决我的问题，因此第一次在这里发布，但是这一次我觉得我有点不高兴。
我有一个在DigitalOcean上运行的VPS，用于个人项目。我很早以前就安装了它，我认为它甚至可能是DO预先为我安装的。它正在运行Ubuntu 14.04，因此我决定是时候对其进行升级了-大错误。
我sudo apt-get update && sudo apt-get upgrade在运行之前运行了一些临时更新sudo do-release-upgrade。
这些问题之一开始出现-似乎apt-get remove无法删除旧的内核版本？但是我可能完全误读了这些信息，因为可悲的是，我对Linux更新并不那么精通。
我将尝试列出我已阅读的所有命令输出，这可能会有用。任何有关如何摆脱这种混乱的技巧都将受到赞赏。
df -hT 输出：
root@web:~# df -hT

udev devtmpfs 487M 4.0K 487M 1% /dev

看来我对服务器上的空间还好

并没有我预期的那么糟。好吧，让我们尝试修复它。
首先，确实要从您的重要数据进行备份。
确保您有足够的空间和inode可用。
df -h;df -i
下一步是重新安装initramfs-tools。找不到命令update-initramfs，这是必需的。
sudo apt install --reinstall initramfs-tools=0.122ubuntu8.16
根据软件包搜索，这是xenial版本，位于xenial-updates中。
如果不可能的话。直接用wget绘制包装
wget -c http://mirrors.kernel.org/ubuntu/pool/main/i/initramfs-tools/initramfs-tools_0.122ubuntu8.16_all.deb
并使用dpkg安装它。
sudo dpkg -i initramfs-tools_0.122ubuntu8.16_all.deb
仅当此程序运行无误时。
sudo dpkg --configure -a && sudo apt-get -f install
检查与
dpkg -l | egrep -v '^ii|rc'
如果所有程序包都处于干净状态。应该像我的
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend
+++-=============================================-========================================-============-===============================================================================
然后就可以准备升级了。
sudo apt-get update && sudo apt-get dist-upgrade
