I have updated my Ubuntu version to 18.04. Now when I try to start Packet Tracer via /opt/pt/bin/PacketTracer7 I get lots of those messages:

"Warning: libpng warning: iCCP: known incorrect sRGB profile"

I also got those ones:

QFSFileEngine::open: No file name specified
"INFO  - Qt Version: 5.5.1"
QFSFileEngine::open: No file name specified
Warning: QT_DEVICE_PIXEL_RATIO is deprecated. Instead use:
   QT_AUTO_SCREEN_SCALE_FACTOR to enable platform plugin controlled per-screen factors.
   QT_SCREEN_SCALE_FACTORS to set per-screen factors.
   QT_SCALE_FACTOR to set the application global scale factor.

Warning: libpng warning: iCCP: known incorrect sRGB profile
Warning: QObject::connect: No such slot CLogicalToolbar::showViewport()
Warning: QObject::connect:  (receiver name: 'CBaseLogicalToolbar')

I also tried gitgudgithub's answer from here: Packet Tracer 7 on Ubuntu 18.04 cannot launch. Got this message as a result:

error while loading shared libraries: libicui18n.so.52: cannot open shared object file: No such file or directory

The problem is that i got libicu60 installed. I have know idea what to do. Any idea about fixing this?

Fixed this! Just needed to install another version of the package. Then just execute

packettracer

And everything will work fine!
