Ubuntu 19.04 上的 Packet Tracer 7.2 没有可用的版本信息

我正在尝试在 Ubuntu 19.04 上安装 Packet Tracer，但是当我尝试启动它时出现以下错误：

./PacketTracer7: ./libcrypto.so.1.0.0: no version information available (required by ./PacketTracer7)

但是当我尝试安装时libssl1.0.0出现以下错误：

**Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package libssl1.0.0 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source**

**E: Package 'libssl1.0.0' has no installation candidate**

我还收集了此的调试：

提前感谢你的帮助。再次抱歉，我缺乏技术知识来解释这个问题。

您可以尝试从下载18.10 存储库，因为它在 19.04 还不可用。

wget http://security.ubuntu.com/ubuntu/pool/main/o/openssl1.0/libssl1.0.0_1.0.2n-1ubuntu6.2_amd64.deb
sudo dpkg -i libssl1.0.0_1.0.2n-1ubuntu6.2_amd64.deb

我在让 PT 在 Ubuntu 19.04 上运行时遇到了一些麻烦，经过一番研究，我发现不仅需要 libpng12 包，而且由于 /lib 现在是 /usr/lib 的符号链接，因此需要进一步自定义。虽然我很感谢大家提供自定义 .deb 包的链接，但我想自己动手

假设 PacketTracer 7.2.2 已安装到 /opt/pt

#create dir to hold libpng12
sudo mkdir /opt/pt/libpng
cd /opt/pt/libpng

#obtain official package
sudo wget http://security.ubuntu.com/ubuntu/pool/main/libp/libpng/libpng12-0_1.2.54-1ubuntu1.1_amd64.deb .

#extract package
sudo dpkg-deb -x libpng12-0_1.2.54-1ubuntu1.1_amd64.deb ./libpng12
