包裹数据包追踪器指的是Cisco Packet Tracer 7.3。我的操作系统是 Ubuntu 20.04。
我安装了 packettracer,但是该软件包需要一个qt-在spi我在 Ubuntu 20.04 存储库中找不到该软件包。
$sudo dpkg -i PacketTracer_730_amd64.deb

我搜索了该包,但我找到的只是qt-在spi对于 Ubuntu 18.04。我尝试安装它,但它还需要其他包。

我再次搜索了其他软件包(libqt4-dbus、libqtcore4、libqtgui4),但我发现的仅适用于 20.04 以下的 Ubuntu 版本(即 18.04、19.04、19.10),没有适用于 Ubuntu 20.04 的软件包。
我继续尝试安装这些软件包,但它们又依赖于其他不可用的软件包,等等。
我尝试安装Qt-5。安装了 Qt-5.12.8,但我仍然没有得到qt-在spi包裹。
Packettracer 似乎甚至不需要qt-在spi,因为它可以正常运行,没有错误。但是,当我尝试安装另一个包(不管它是什么)时,出现了依赖性错误:
packettracer : Depends: qt-at-spi but it is not installable
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
因此,我必须先运行“apt --fix-broken install”并卸载 packettracer,然后才能安装另一个软件包。然后,当另一个软件包安装完成后,我又重新安装了 packettracer。这很烦人。

问题是:
- 您能帮忙找到适用于 ubuntu 20.04 的 qt-at-spi 吗?或者
- 我可以从 apt --fix-broken install 中排除 packettracer 吗?
答案1
按着这些次序 :
cd Desktop
mkdir working-dir
cd working-dir
cp ~/Downloads/PacketTracer_730_amd64.deb .
ls
wget http://ftp.br.debian.org/debian/pool/main/d/double-conversion/libdouble-conversion1_3.1.0-3_amd64.deb http://archive.ubuntu.com/ubuntu/pool/main/libj/libjpeg-turbo/libjpeg-turbo8_2.0.3-0ubuntu1_amd64.deb http://archive.ubuntu.com/ubuntu/pool/main/libj/libjpeg8-empty/libjpeg8_8c-2ubuntu8_amd64.deb
ls -l
chmod +x *
ls -l
sudo dpkg -i *
sudo featherpad /var/lib/dpkg/status #featherpad here, is my text editor
#ctrl+f (search) > Depends: libdouble-conversion1, qt-at-spi > (delete-this-line) > save & close
sudo apt --fix-broken install
packettracer
我还在 YouTube 上发布了一个视频https://www.youtube.com/watch?v=5FuBKG49bIY它展示了相同的过程但可能会更有帮助。
答案2
在 20.04 focus 上。除 qt-at-spi 外,没有依赖性问题。
在下载的目录中PacketTracer_730_amd64.deb:
sudo dpkg -i *
sudo vi /var/lib/dpkg/status
使用/
搜索,然后输入qt-at-spi
。
使用x
删除“,qt-at-spi”,然后<shift>:wq
写入/保存并退出。
sudo apt --fix-broken install
谢谢你们!
