无法升级到22.04，因为“`ubuntu桌面”在升级后出现故障

Question

我尝试使用软件更新程序从20.04更新到22.04。当尝试创建“新软件通道”时，它失败了。/var/log/dist-upgrade/main.log中的错误是

2022-10-23 16:55:26,408 WARNING Can't mark 'ubuntu-desktop' for upgrade (E:Unable to correct problems, you have held broken packages.)
2022-10-23 16:55:34,181 ERROR Dist-upgrade failed: 'Broken packages after upgrade: ubuntu-desktop'

由于某些原因，ubuntu-desktop没有更新。/var/log/dist-upgrade/apt.log为ubuntu-desktop展示了这个。

我读过以前的答案，它与我安装的外部ppa相关。但从日志中我找不出要删除什么。这是我的/etc/apt/sources.list.d

任何关于如何解决这个问题的建议都会很有帮助。

您有一个令人印象深刻的第三方PPA列表。这给您提供了一个不标准的系统，因此可能无法升级。

也许，清除每个PPA，即移除PPA及其附带的软件，可能会使您恢复到一个可以再次更新的标准系统(前提是您将其与sudo apt full-upgrade完全更新)。然后可以在upgrade.Note之后添加这些内容，您有责任检查它是否适合新的Ubuntu版本。一些PPA继续工作，在其他情况下，一个专用的PPA可用于新版本，在某些情况下，可能没有合适的PPA。

但是，重新安装reinstall并重新配置系统也同样容易。优点是，您将有一个干净的系统，旧的过时的配置已经消失。
