从 Ubuntu MATE 21.10 Impish 升级到 Ubuntu MATE 22.04 Jammy 后，当我运行时lsb_release出现此错误：
$ lsb_release

我发现lsb_release错误的方式是因为mate-menu（高级 MATE 菜单）停止工作（从任务栏中消失），当我尝试重新安装它（使用 Synaptic）时，出现此错误：
E: mate-menu: package is in a very bad inconsistent state; you should reinstall it before attempting configuration

虽然我找到了这些类似的线程，但它们对我来说不起作用。谢谢。

正如@steeldriver 评论中所建议的，我切换了ln -s命令中的参数。 撤销它解决了该问题：
sudo ln -s /usr/bin/python3.10 /usr/bin/python3
