Hello. I am completely new to gns3. Should ubridge be made a dependency to gns3-server or gns3-gui?

When I try to add the cloud in the gns3-gui I get an error complaining about ubridge. Installing the aur/ubridge appears to resolve that issue.

Similarly dynamips is probably also a good idea to add as dependency

EDIT: Fixed it by downgrading python-charset-normalizer to 2.1.1-1

Hi, I get an error when I tried to start gns3-server@user service, running gns3server outputs:

Traceback (most recent call last):

jsonschema requirement should be fixed now – I hope it works with the newer version, too.

3Jl0y_PYCCKUi commented on 2022-10-10 15:07 (UTC)

The service does not start with python-jsonschema from the arch linux repositories, it might solve the problem by creating a separate python-jsonschema package for gns3, for example alpine did so

I just built this version of the python-jsonschema package and everything worked, with no modifications except updpkgsums

I actually have the same issue as @jpbd. What do yo mean with rebuild?

I have removed the package and reinstalled it but with the same result.

EDIT: rebuilding means removing the aur helper cache if you have that and reinstalling. That fixed it for me indeed.

@jpbd, rebuild gns3-server

s13g3lb4um: Thanks. I've patched the requirements to allow async-timeout>=3.0.1 but aiohttp>=3.7.4 was already there, so that should have worked already.

s13g3lb4um commented on 2021-11-30 07:29 (UTC)

the initial setup fails for me, this installed aiohttp==3.8.1 and async-timeout==4.0.1, but this package require async-timeout==3.0.1.

i unninstall aiohttp and async-timeout, after i install aiohttp==3.7.4 and async-timeout==3.0.1 and this works.
