我正在运行sudo update-manager -d并启动升级过程。我选择升级选项，然后当管理员进入时，Setting new software channels它抛出一个错误。
无法计算升舱 计算升级时出现无法解决的问题。 这可能是由以下原因造成的： * 升级到 Ubuntu 的预发布版本 * 运行当前预发布版本的 Ubuntu * Ubuntu 未提供的非官方软件包 如果这些都不适用，那么请在终端中使用命令“ubuntu-bug ubuntu-release-upgrader-core”报告此错误。
我已禁用所有非官方和第三方软件包，由于我使用的是 13.04，因此我没有运行预发布版本，并且我正尝试更新到非预发布的 beta 2。在我填写错误报告之前，由于我的两个系统都遇到了这个问题，我想弄清楚是否有其他人遇到过同样的问题。

答案1
对我有用的是删除所有损坏的包裹，因为它们阻碍了升级。
首先找出哪些包裹已损坏：
grep Broken /var/log/dist-upgrade/apt.log
然后删除它们：
sudo apt-get remove <packages to remove>
有些可能会在升级期间重新安装，其他的您可能需要自行重新安装。
答案2
系统升级失败后，请检查文件/var/log/dist-upgrade/main.log
我找到了这一行：
2013-10-17 15:00:30,543 ERROR Dist-upgrade failed: 'The package 'xubuntu-desktop' is marked for removal but it is in the removal blacklist.'
我手动删除了 xubuntu-desktop。然后升级继续进行，没有任何问题。
答案3
这里也有类似的问题。上一篇文章中指出的“main.log”文件中的最后几行是：
2013-10-17 23:44:38,233 DEBUG blacklist expr 'unity$' matches 'unity'
2013-10-17 23:44:38,233 DEBUG The package 'unity' is marked for removal but it's in the removal blacklist
2013-10-17 23:44:43,585 ERROR Dist-upgrade failed: 'The package 'unity' is marked for removal but it is in the removal blacklist.'
2013-10-17 23:44:43,586 DEBUG abort called

手动卸载 Unity 并继续升级。不太清楚是什么导致了这个问题，也不太清楚这是否真的是一个好的“解决方案”，但我想我会在更新完成后找到答案？！？
答案4
就我的情况而言，问题是由抓住状态。放回安装国家解决了这个问题。
放入或移除包的可能方法抓住state 正在使用dpkg。首先，获取所有包的当前状态，并将其放入文件中：
dpkg --get-selections > myselection
然后，编辑文件并替换install为hold，反之亦然。最后，设置新的选择：
sudo dpkg --set-selections < myselection
sudo apt-get update
sudo apt-get upgrade
