Packet Tracer 7.2 on Ubuntu 19.04 no version information available

Question

I am trying to install Packet Tracer on Ubuntu 19.04, but it gives me the error below when I try to launch it:

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

But when I try to install libssl1.0.0 I get the following error:

**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**

I also collected a debug for this:

Reading symbols from PacketTracer7...

(gdb) run

Thanks in advance for helping me. And again, excuse my lack of technical knowledge to explain this issue.

Answer 1

You can try downloading one from 18.10 repository, since it's yet to be available on 19.04.

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

Answer 2

I ran into some trouble getting PT to run on Ubuntu 19.04 and after a bit of research it looks like not only is the libpng12 package required but it needs further customization due to /lib being a symlink to /usr/lib now. While I appreciate the folks dropping links to custom .deb packages I wanted to roll my own

Assumes PacketTracer 7.2.2 has already been installed to /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
