Can't Open GNS3 in Manjaro after an update

Support Third-party Applications
1

Hi, I was using the program just fine a while a go.
I posted this issue in the official forum of the application but they tell me to ask in the Manjaro forum.
Unfortunately I don’t know exactly what update that broke the application for me because it’s been a while that I used the GNS3 application.
This week, I tried to run it, but I’m getting this output in terminal:

/usr/lib/python3.10/site-packages/pkg_resources/init.py:116: PkgResourcesDeprecationWarning: 2.0.5-build-libtorrent-rasterbar-src-libtorrent-rasterbar-2.0.5-bindings-python is an invalid version and will not be supported in a future

I didn’t manage to figure this out, can someone help me?

See if this helps… :arrow_down:

Hi Aragorn, thanks for your quick response!
I tried that and it didn’t work, BUT you pointed me to the right direction.
I uninstalled and reinstalled both gui and server application, and that did the trick (shame I didn’t think of that simple solution before).
I lost some configs but that isn’t a big deal for me.
Thanks again for the help!

sudo pip3 uninstall gns3-gui
sudo pip3 uninstall gns3-server
sudo pip3 install gns3-gui
sudo pip3 install gns3-server
