Initially, I had this problem after installing Cisco Packet Tracer 7.2.2
user@linux:~$ /opt/pt/bin/PacketTracer7
/opt/pt/bin/PacketTracer7: error while loading shared libraries: libQt5WebKitWidgets.so.5: cannot open shared object file: No such file or directory
user@linux:~$
It turns out 5 libraries were not found.
user@linux:~$ ldd /opt/pt/bin/PacketTracer7 | grep no
libQt5WebKitWidgets.so.5 => not found
libQt5WebKit.so.5 => not found
libQt5Multimedia.so.5 => not found
libQt5ScriptTools.so.5 => not found
libQt5Sql.so.5 => not found
user@linux:~$
I followed suggestion from chili555 and managed to fix 4 of them https://askubuntu.com/a/987765/769117
sudo apt install libqt5webkit5 libqt5multimedia5 libqt5printsupport5 libqt5script5 libqt5scripttools5
Then, I launched PacketTracer7 and found another one was missed which was libQt5Sql.so.5.
user@linux:~$ /opt/pt/bin/PacketTracer7
/opt/pt/bin/PacketTracer7: error while loading shared libraries: libQt5Sql.so.5: cannot open shared object file: No such file or directory
user@linux:~$
Checked ldd again, and verified libQt5Sql.so.5 was missing. The other 4 were fixed on previous update.
user@linux:~$ ldd /opt/pt/bin/PacketTracer7 | grep no
libQt5Sql.so.5 => not found
user@linux:~$
I tried to installed it but didn't work
user@linux:~$ sudo apt install libQt5Sql
Reading package lists... Done

E: Unable to locate package libQt5Sql
user@linux:~$
I did not see anything helpful in syslog
user@linux:~$ cat /var/log/syslog | grep acket
user@linux:~$
What should I do to fix this?
Had the same issue. All of those libs are present in /opt/pt/bin, so if you start PacketTracer from there, it will work.
