By the way, the package released for 17.10, working back then for the beta, doesn't work anymore.

It reports dependency issues without possibility to install packages:

Update for kubuntu case - with the fresh install there is no issue. Default there is python 3.6 but user has 3.5 so he has updated Kubuntu but we need to have an information from which version.

Hi @AJNOURI ,
I've tried with the fresh install of Ubuntu 17.10 and also haven't experienced any issue.
Have you installed gns3-gui on the fresh copy? Or were you upgrading Ubuntu or GNS3? Many thanks!

Cheers,
Dominik

Can't install on kubuntu 17.10.
It says "Unable to locate package gns3-gui"

Can't install on kubuntu 17.10. It says "Unable to locate package gns3-gui"

I can see it there:

What are the steps you have done to try to install gns3-gui?

[z4kio]

sudo add-apt-repository ppa:gns3/unstable && sudo apt update && sudo apt install gns3-gui

and also tried adding this ppa before "sudo add-apt-repository ppa:gns3/ppa"
but the result is same.

Hi @z4kio,
Could you try again:

sudo add-apt-repository ppa:gns3/ppa
sudo apt update
sudo apt install gns3-gui

?
We've done some changes to related packages and everything seems to fine during the upgrade time.
Thank you,
Dominik

Hi @z4kio ,
I've made small changes to packages. Could you test now?
Please let me also know if it helps.
Thank you,
Dominik
