Cisco Packettracer 无法启动

  • 772

尝试安装和运行Cisco packettracer 7。

显然，因为：

似乎安装了正确的库，但 CPT 需要旧版本 - 52 而不是 55。包含旧版本 libicui18n 的 Debian 软件包可在 http://security.ubuntu.com/ubuntu/pool/main/i/获得icu/libicu52_52.1-3ubuntu0.8_amd64.deb。

手动安装旧包：

thufir@dur:~/deb$

结果相同。已安装的软件包包括：

sudo apt install libqt5webkit5 libqt5multimedia5 libqt5xml5 libqt5script5 libqt5scripttools5
software-installation networking cisco make ps

  1. 从这里下载 libpng12 包，然后用你的包管理器安装它，或者sudo dpkg -i <package>

    我只需要安装这个包就可以了。

    这些软件包似乎已经解决了这个问题：

    thufir@dur:~/deb$ 
thufir@dur:~/deb$ sudo dpkg -i libicu52_52.1-3ubuntu0.8_amd64.deb libpng12-0_1.2.54-1ubuntu1_amd64.deb

    虽然我不确定这就是所需要的，但我也安装了其他软件包。
