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
Building dependency tree       
Reading state information... 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?

  • Did you start with sudo apt update? The package exists in all recent Ubuntu versions. Which is yours? lsb_release -d – chili555 Nov 30 '19 at 15:40

Had the same issue. All of those libs are present in /opt/pt/bin, so if you start PacketTracer from there, it will work.

If after execute command "ldd yourExecutable", the end tell you "libQt5Sql.so.5 => not found", execute command:

apt-cache search libQt5Sql

to search relevant libs. The searched results:

libqt5sql5 - Qt 5 SQL module

libqt5sql5-ibase - Qt 5 Firebird database

driver libqt5sql5-mysql - Qt 5 MySQL database driver

libqt5sql5-odbc -Qt 5 ODBC database driver

libqt5sql5-psql - Qt 5 PostgreSQL databasedriver

libqt5sql5-sqlite - Qt 5 SQLite 3 database driver

libqt5sql5-tds - Qt 5 FreeTDS database driver

Seeing from the results that you need "libqt5sql5". after execute command:

sudo apt-get install libqt5sql5

"libQt5Sql.so.5" will be installed. if you want to know where it is installed at ,execute command

sudo find / -name "libQt5Sql.so.5"

If you need to write data into mysql, "libmysqlclient.so.21" should also be installed. execute command:

apt-cache search libmysqlclient

to search relevant libs. The searched results:

libmysqlclient-dev - MySQL database development files

libmysqlclient21 - MySQL database client library

default-libmysqlclient-dev - MySQL database development files (metapackage)

libcrypt-mysql-perl - Perl module to emulate the MySQL PASSWORD() function

libglpk40 - linear programming kit with integer (MIP) support

librust-mysqlclient-sys-dev - Auto-generated rust bindings for libmysqlclient - Rust source code

Seeing from the results that we need "libmysqlclient21", after execute command:

sudo apt-get install libmysqlclient21

"libmysqlclient.so.21" will be installed.
