Could not calculate the upgrade
An unresolvable problem occurred while calculating the upgrade.
If none of this applies, then please report this bug using the
command 'ubuntu-bug ubuntu-release-upgrader-core' in a terminal. If
you want to investigate this yourself the log files in
'/var/log/dist-upgrade' will contain details about the upgrade.
Specifically, look at 'main.log' and 'apt.log'.
我/var/log/dist-upgrade/main.log看到以下内容
2022-09-10 19:16:11,956 DEBUG Marking 'ubuntu-desktop' for upgrade
2022-09-10 19:16:12,108 WARNING Can't mark 'ubuntu-desktop' for upgrade (E:Unable to correct problems, you have held broken packages.)
2022-09-10 19:16:12,350 ERROR Dist-upgrade failed: 'Broken packages after upgrade: ubuntu-desktop'
但是我找不到任何被扣留的破损包裹。sudo dpkg --get-selections | grep hold是空的。
运行sudo apt update && sudo apt upgrade并没有发现任何奇怪的事情

经过反复试验，并查看了 /var/log/dist-upgrade/apt.log，很明显，问题主要是由 Python 3.10 软件包（及其依赖项）和其他几个已安装的应用程序（如 Zoom）引起的。删除这些软件包后（我使用了 Synaptic 软件包管理器），升级顺利完成。
