我一直尝试将我的 ubuntu 16.04lts 更新到 18.04lts，但出现以下错误：
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
当我检查 /var/log/dist-upgrade/apt.log 中的错误日志时，我得到的结果如下
