I have installed Cisco Packet Tracer 7.1.1 on Ubuntu 18.04. Every time I launch the application it closes and give me a message Segmentation fault (core dumped)
.
Using the gdb
, I went to the installation directory /opt/pt/bin
and I typed the following commands:
$gdb Packettracer
$gdb > run
$gdb > where
Which reports a problem with libpng
and libcrypto.so.1.0.0
Warning: libpng warning: iCCP: known incorrect sRGB profile
Warning: libpng warning: iCCP: known incorrect sRGB profile
Thread 1 "PacketTracer7" received signal SIGSEGV, Segmentation fault.
0x00007ffff79f49a7 in CRYPTO_add_lock () from /usr/lib/x86_64-linux- gnu/libcrypto.so.1.0.0
How can i fix this?
libssl1.0.0
package, which has a lot of reverse-dependencies. As alternative you may try previous version of CPT. But CPT 7.1.1 works on 16.04 LTS (see my answer).
