解决dpkg错误代码(1)：systemd与python3配置失败导致无法安装软件的问题求助

我现在完全卡壳了，一直碰到同一个错误，根本没法正常操作——既装不了任何软件，网上帖子里别人说的各种修复方法也都不管用。

安装Firefox时的错误详情 #

当我执行sudo apt-get install firefox时，出现了以下错误：

The following packages were automatically installed and are no longer required:
libmpdec3 libpython3-stdlib libpython3.10-minimal libpython3.10-stdlib
python3 python3-minimal python3.10 python3.10-minimal
Use 'sudo apt autoremove' to remove them.

The following additional packages will be installed:
apparmor dbus dbus-user-session dirmngr fuse3 gnupg gnupg-l10n gnupg-utils

强制安装也没用，我尝试安装Chrome、Chromium、Brave等其他浏览器时，都会出现相同的错误。

执行sudo dpkg --configure -a时的错误详情 #

我试过重新配置dpkg，但完全不管用，执行这个命令后出现了一堆错误：

我真的快被逼疯了，网上大家说的唯一解决办法就是重新配置dpkg，但这根本没用。有没有大佬知道怎么解决这个问题啊？
