Kubuntu 16.04 升级失败（xserver-xorg-video-all 有问题？）

我正在尝试升级我的 Kubuntu Wily 15.10 计算机，但是失败了。

我正在这样做：

$ sudo do-release-upgrade -m desktop

这是我得到的：

Calculating the changes

Could not calculate the upgrade 

An unresolvable problem occurred while calculating the upgrade. 

This can be caused by: 
* Upgrading to a pre-release version of Ubuntu 
* Running the current pre-release version of Ubuntu 
* Unofficial software packages not provided by Ubuntu 

If none of this applies, then please report this bug using the 
command 'ubuntu-bug ubuntu-release-upgrader-core' in a terminal.

我在以下网址找到了它/var/log/dist-upgrade/main.log：

我能做些什么？

答案1

我可以解决。我遵循这个答案的建议：https://askubuntu.com/a/367329/483417

我所做的是：

sudo apt-get remove xserver-xorg-video-all
sudo do-release-upgrade -m desktop

我等待升级结束并重新启动计算机。之后，Kubuntu 启动顺利。图形也配置好了。我认为这是因为我有一块 nvidia 显卡，驱动程序升级重新安装了所有内容，甚至xserver-xorg-video-all。

最后，我的 Kubuntu 是 Xenial :-)
