因此我在尝试升级 Ubuntu 16.04 时遇到了困难。
运行更新命令时我得到以下信息：
$ sudo apt-get upgrade

Calculating upgrade... Done
The following packages were automatically installed and are no longer required:
linux-headers-4.10.0-28 linux-headers-4.10.0-28-generic linux-headers-4.8.0-36 linux-headers-4.8.0-36-generic linux-image-4.10.0-28-generic
linux-image-4.8.0-36-generic linux-image-extra-4.10.0-28-generic linux-image-extra-4.8.0-36-generic
Use 'sudo apt autoremove' to remove them.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
2 not fully installed or removed.
After this operation, 0 B of additional disk space will be used.
Do you want to continue? [Y/n]
