我想在我的 Ubuntu 20.04 上安装。它给出了这个错误：
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
onboard : Depends: python3 (< 3.8) but 3.8.2-0ubuntu2 is to be installed
Recommends: gir1.2-ayatanaappindicator3-0.1 but it is not going to be installed
Recommends: gir1.2-atspi-2.0 but it is not going to be installed
Recommends: onboard-data (>= 1.4.1-4) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
我安装了 3 个 Python 版本 (3.8.10 <- 预装、3.10.4 和 3.11.0a7)。apt只检测 Python 3.8。可以修复吗？
编辑：我确信我的系统不包含损坏的软件包（当我安装其他东西时不会出现错误）。所以我认为这与安装有关。
