How to install new Cisco Packet Tracer 7.3 on Fedora 31 Workstation?

Oh for the error below i found a solution:

Fatal: This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
Available platform plugins are: linuxfb, xcb.
/opt/pt/ptdebug: line 8:  3756 Aborted                 (core dumped) ./PacketTracer7 "$@"
  1. Deinstalled flatpak (flatpak sort of uses their own version of libraries for qt5, plugins, libcrypto and openssl, no wonder my system got confused), which I wasn’t using anyways.
  2. Reinstalled qt5, libxcb
  3. Deleted packet tracer 7.3
  4. Reinstalled packet tracer 7.3
    Note that my kernel is 5.7.10-201.fc32.x86_64.

For anyone who needs it I leave commands down:

dnf remove flatpak
dnf reinstall qt5-*
dnf reinstall libxcb

Then uninstalled Packet Tracer 7.3

rm -rvf /opt/pt
rm -rvf /usr/share/applications/cisco-pt7.desktop
rm -rvf /usr/share/applications/cisco-ptsa7.desktop
rm -rvf /usr/share/icons/hicolor/48x48/apps/pt7.png

And lastly I installed Packet Tracer 7.3 again following instructions.

Thanks guys

Hello.

I am trying to use the folder tmp but looks like it is locked on my computer and there is no modifications allowed. Can you please let me know how to change the settings and do this changes as a super user.

Hello,
Open a terminal.

Is your account member of the wheel group ?
If you don’t know, type:
id YOUR_ACCOUNT

If it is then type:
sudo -s
(type your password)
The /tmp folder should be accessible.

If not, add your account to wheel group.
1. Type:
su -
(type root password)
usermod -aG wheel YOUR_ACCOUNT

2. Close the terminal

3. Close your session and login

4. Open a terminal and verify if /tmp is accessible now.

For more information about sudoers,
see: Adding a user to sudoers :: Fedora Docs

Regards.

Thank you for that philpinch.

Unfortunately have applied the changes but still I am not allowed to do any changes into tmp folder.
Can’t delete, can’t copy, can’t rename… basically nothing. As well, into tmp folder settings shows that I am allowed only access but nothing else.

"
[root@localhost ~]# id x
uid=1000(x) gid=1000(x) groups=1000(x),10(wheel)
"

When I am trying to install the Packet Tracer and copy the file into tmp it just doesn’t work.

25

Then just use the all mighty sudo su , I think pretty much ran all commands as root and my installation went just fine.

26

I suppose to copy first the Packet Tracer file into tmp folder prior installation but I can’t do this.

Which command shell I use to be able to copy PT into tmp please.

My “PacketTracer_730_amd64.deb” file it is located into “/home/x/Downloads/Retelistica/Packet Tracer”.

27

Follow this, but double-check my commands because I didn’t :

sudo su
mkdir /tmp/pt730
cp /home/x/Downloads/Retelistica/Packet\ Tracer/PacketTracer_730_amd64.deb /tmp/pt730
cd /tmp/pt730

You would really benefit on spending an hour or two on an introductory tutorial on linux command line 101 or something.

Done that already but as I said before, the tmp doesn’t allow any changes.

I am in the same situation, I can’t move anything in tmp. This directory simply doesn’t accept changes.

Hi,

Instead of using /tmp, create a temporary directory in your home directory.

in step 3 I’m typing : mkdir -p tmp/pt730.
The directory is tmp/pt730 (it meams $HOME/tmp/pt730) but not /tmp/pt730.

Regards,
Phil

Hi,
The Packettracer 7.3.1 installation on Fedora 32 Workstation is in the same way as 7.3.0.

This setup also works on a Rhel 8.
