请注意，我无法物理访问该服务器。
但是我可以使用 WinSCP 或 WEBmin。
我使用 Linux 内核 4.10.0-35-generic；Ubuntu 16。
我的 80GB 硬盘（根）甚至太小，无法更新某些软件包。

答案1
根据您的输出，df -h您没有遇到/（根文件系统）大小的问题。
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/WeBuntu--vg-root 72G 18G 51G 27% /
/dev/sda1 236M 236M 0 100% /boot
您的可用字节数为 0 /boot，这是一个问题。
安装 Byobu 包并sudo apt-get install byobu运行sudo purge-old-kernels && sudo apt-get autoremove。
