更新到版本 20.04 后（强制使用 -d 命令），我现在无法使用 termical 或使用软件进行更新或升级。
import apt_pkg
ImportError: libapt-pkg.so.6.0: cannot open shared object file: No such file or directory

上次尝试更新时又出现了这个问题，而且电池图标旁边还有一个红色标记，上面写着“检查更新时出现问题”
cd /etc/apt/sources.list.d/ 中的内容

任何帮助都将不胜感激。我是 Ubuntu 新手。
编辑：
sudo apt upgrade给出此错误：
E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.

也许有人可以解释为什么以下内容对我有用。
我从 Ubuntu 18 升级到 20 时中断了，我知道升级没有完成。所以我运行了 sudo apt update 和 sudo apt upgrade，结果出现了以下错误，与楼主的错误非常相似。
sudo apt update
Traceback (most recent call last):

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
gnupg : Depends: gpgv (>= 2.2.19-3ubuntu2.1) but 2.2.4-1ubuntu1.4 is installed

sudo apt --fix-broken install
没有解决任何问题。但是，我随后运行了以下所有命令：
sudo apt --fix-broken install gnupg
sudo apt --fix-broken install gnupg-utils
sudo apt --fix-broken install gpg
sudo apt --fix-broken install gpgconf
sudo apt --fix-broken install gpgsm
sudo apt --fix-broken install grub-common
sudo apt --fix-broken install grub2-common
sudo apt --fix-broken install initramfs-tools-core
sudo apt --fix-broken install klibc-utils
sudo apt --fix-broken install libpython3.8-stdlib
sudo apt --fix-broken install python3-apt
sudo apt --fix-broken install systemd-sysv
请注意，运行完每个命令后，似乎没有取得任何进展（每个命令后都会显示上述相同的错误消息 -The following packages have unmet dependencies:运行完每个命令后都会显示依赖项列表）。
但是，运行所有这些命令之后，以下内容有效：
sudo apt --fix-broken install
sudo apt update重新启动并运行后sudo apt upgrade，从 Ubuntu 18 到 Ubuntu 20 的升级就完成了。
