Dependancy issue : wxpython, python2-gobject

[QuentinM]

Hello, everyone,

I’m currently using Fedora 32,

When i try to install the RPM provided on this site, i have this issue:

dnf install DisplayCAL-3.8.9.3-1.1.x86_64.rpm

conflicting requests
- nothing provides wxPython >= 2.8.11 needed by DisplayCAL-3.8.9.3-1.1.x86_64
- nothing provides python2-gobject needed by DisplayCAL-3.8.9.3-1.1.x86_64

But  wxPython is installed :, through the python3-wxpython4 package, when i test :

pip list --format=columns | grep wxPython
wxPython 4.0.7

and i have already installed the pygobject2 package too,

Who has an idea to solve this?

There is no Python3 version (yet).

Got it, for those facing the same issue you have to force the use of python2 :

1- After installing the displaycal recommended devel libraries  use python 2 and pip to get the needed pyhon modules installed,

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

python get-pip.py

python2 -m pip install PyGObject

python2 -m pip install PyOpenGL

 python2 -m pip install faulthandler

python2 -m pip install -f https://extras.wxpython.org/wxPython4/extras/linux/gtk3/fedora-30/ wxpython

2- Install DisplayCAL with code source

I think the following is a better approach which uses packages from Fedora 31:

wget https://download-ib01.fedoraproject.org/pub/fedora/linux/releases/31/Everything/x86_64/os/Packages/p/python2-wxpython-3.0.2.0-26.fc31.x86_64.rpm https://rpmfind.net/linux/fedora/linux/releases/31/Everything/x86_64/os/Packages/p/python2-gobject-base-3.34.0-3.fc31.x86_64.rpm https://rpmfind.net/linux/fedora/linux/releases/31/Everything/x86_64/os/Packages/p/python2-gobject-3.34.0-3.fc31.x86_64.rpm https://displaycal.net/download/Fedora_31/x86_64/DisplayCAL.rpm

sudo rpm -i python2-wxpython*.rpm python2-gobject*.rpm DisplayCAL*.rpm
