我的 Ubuntu 服务器运行在具有 512mb RAM 的 VPS 上。我将其从 14.04 升级到 16.04。我正在尝试安装 phpmyadmin，但出现了一些错误：

我不知道它是否boot已满或者其他原因导致了这个问题。
答案1
apt-get 命令无法正常运行，因为您的 /boot 分区已达到其最大容量。可能发生的情况是某些内核升级未完全执行，因此 apt-get 卡住并将保持冻结状态，直到您清除 /boot 中的一些空间。通过以下方式找出已安装的内核版本：
dpkg --list 'linux-image*'
检查当前正在使用的版本
uname -r
删除不再需要的内核安装
sudo apt-get remove linux-image-version
用内核版本替换版本。之后
sudo apt-get autoremove
sudo update-grub
最后更新 grub。
