AttributeError: 'Template' object has no attribute 'official'

这是我尝试升级桌面版时得到的结果：sudo do-release-upgrade。还有一个信息：我已安装 kde。

答案1

在 Google 上搜索第一个结果（搜索“AttributeError: 'Template' 对象没有属性 'official'”）会出现下一个 Ubuntu 论坛主题：升级到 10.10：“AttributeError：‘Template’对象没有属性‘official’”。

在升级到 10.10 之前，尝试刷新您的软件包列表并确保您的系统是最新的：

sudo apt-get update && sudo apt-get upgrade
