我没有 root 密码，因此我进入 sudo 超级用户模式，尝试在笔记本电脑上安装 wireshark。我之前尝试过安装 wireshark，但第一次安装时我没有 root 访问权限，因此没有收到任何数据。我删除了该程序并尝试重新安装它，结果收到了这个漂亮的错误消息：
Daniel-Thinkpad daniel # sudo aptitude install wireshark

我不知道该怎么办。
答案1
关键部分是这个。
Most probably the wireshark group exists, but is not a system group.
Please delete the existing group or re-create it as a system group and try configuring wireshark-common again.
尝试使用 删除现有wireshark组（可能是您以前安装 Wireshark 时遗留下来的）sudo groupdel wireshark，然后运行sudo dpkg --configure -a以配置新的 Wireshark 包。
答案2
答案就在你的问题里：
Executing "addgroup --quiet --system wireshark" failed.
Most probably the wireshark group exists, but is not a system group.
Please delete the existing group or re-create it as a system group and try configuring wireshark-common again.
因此删除该群组
sudo delgroup wireshark
sudo addgroup --quiet --system wireshark
sudo apt-get install --reinstall wireshark
