我正在尝试安装需要此软件包的应用程序，当我尝试安装此软件包时，出现上述错误。

我已经使用 apt update 更新了 apt 软件包列表。我能做些什么？

我需要在 64 位 ubuntu 上安装它，它是一个 32 位软件包。

添加架构并没有解决问题：

sudo dpkg --add-architecture i386

sudo apt update

您的 中应该有以下几行/etc/apt/sources.list：

    deb http://security.ubuntu.com/ubuntu bionic-security main universe

由于该软件包属于universe存储库，因此软件包更新是通过安全更新应用的，并且bionic-update：packagekit-gtk3-模块

示例 source.list （更完整）：

deb http://us.archive.ubuntu.com/ubuntu/ bionic main restricted universe multiverse
deb http://us.archive.ubuntu.com/ubuntu/ bionic-security main restricted universe multiverse
deb http://us.archive.ubuntu.com/ubuntu/ bionic-updates main restricted universe multiverse
deb http://us.archive.ubuntu.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb http://us.archive.ubuntu.com/ubuntu/ bionic-backports main restricted universe multiverse
deb http://archive.canonical.com/ubuntu/ bionic partner

然后运行：

sudo apt update
sudo apt install packagekit-gtk3-module:i386
