为 ubuntu 20.04 寻找 qt-at-spi

  • 772

包packettracer指的是Cisco Packet Tracer 7.3。我的操作系统是 Ubuntu 20.04。

我安装了 packettracer，但该软件包需要一个我在 Ubuntu 20.04 存储库中找不到的qt-at-spi软件包。

$sudo dpkg -i PacketTracer_730_amd64.deb
Selecting previously unselected package packettracer.
(Reading database ... 199702 files and directories currently installed.)
Preparing to unpack .../PacketTracer_730_amd64.deb ...

我搜索了那个包，但我发现只有qt-at-spi for ubuntu 18.04。我尝试安装它，但它还需要其他软件包。

$ sudo dpkg -i qt-at-spi_0.4.0-8_amd64.deb 
Selecting previously unselected package qt-at-spi:amd64.

 qt-at-spi:amd64 depends on libqtcore4 (>= 4:4.8~); however:

 qt-at-spi:amd64 depends on libqtgui4 (>= 4:4.8~); however:
  Package libqtgui4 is not installed.

dpkg: error processing package qt-at-spi:amd64 (--install):

Errors were encountered while processing:
 qt-at-spi:amd64

我再次搜索了其他软件包（libqt4-dbus、libqtcore4、libqtgui4），但我发现仅适用于 20.04 以下的 Ubuntu 版本（即 18.04、19.04、19.10），Ubuntu 20.04 没有。

我一直在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，依此类推。

我试图安装Qt-5。安装了 Qt-5.12.8 但我仍然没有得到qt-at-spi包。

Packettracer 甚至似乎不需要qt-at-spi，因为它运行正常而没有错误。但是，当我尝试安装另一个包（不管它是什么）时，出现依赖错误：

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包。然后，当安装了另一个软件包时，我再次重新安装了 packettracer。这很烦人。

$ sudo apt --fix-broken install

问题是：

  • 你能帮忙找到 ubuntu 20.04 的 qt-at-spi 吗？或者
  • 我可以从 apt --fix-broken install 中排除 packettracer 吗？

    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 https://www.youtube.com/watch?v=5FuBKG49bIY上放了一段视频，它显示了相同的过程，但可能更有帮助。

  2. 在 20.04 焦点上。除了 qt-at-spi 之外没有依赖问题。

    在您下载PacketTracer_730_amd64.deb的目录中：

    sudo dpkg -i *
sudo vi /var/lib/dpkg/status

    用于/搜索，然后键入qt-at-spi。

    用于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！
