Fedora 43, Does Not Launch

[cprin21]

Traceback (most recent call last):
  File "/usr/bin/davinci-helper", line 5, in <module>
    from davinci_helper.main import main
ModuleNotFoundError: No module named 'davinci_helper'

I understand that Fedora 43 is pre-beta, and not (yet) listed under supported distros, not expecting a fix but this is a heads up that it currently does not launch.

[cprin21]

Fedora 43 is now in beta.

I'm on 42 and am having the same issue, any chance you were able to fix this?

Unfortunately no, and going through things it may be a different issue on 42 - the issue on 43 is that 43 is not included in the files at all so it doesn't launch because it doesn't know what to do. I just followed the wiki steps to do what the gui does but via the command line.

Im having the same issue.
Trying to figure why, at this point, but thought I'd post in here to let you know

What wiki?

43 just launched, it is now the stable version of Fedora.
And can confirm Davinci Helper doesn't launch in 43.

[pwrdryl]

Same issue here. I just updated the official release of 43

[cprin21]

What wiki?

trying to do this myself, i got it to launch davinchi but after half a second it crashes on the project selection screen with this crash log:

is there any extra stuff you did besides what was listed @cprin21?

Hey,

Managed to get it working by using the Distrobox method:

To put it simply, it runs a fedora 42 container within your system (ig, new to Linux)
https://github.com/zelikos/davincibox
this vid explain how to set it up, but it's quite straight forward
https://www.youtube.com/watch?v=mdPZBe_CKOk

At least for now, seems like a good workaround

[DevintheSeventh]

Having this same issue rn

How is the performance compared to run it using Davinci helper?

[yotamguttman]

Also having an issue, not only would Resolve not launch but also DavinciHelper won't launch...

[slavkosky]

Fedora 43 here as well, davinci-helper doesn't launch for me. Here were my steps:

1. Installed davinci-helper package via the copr repo (completed without error)
2. Find out where davinci-helper was installed:

me@linux:/$ which davinci-helper
/usr/bin/davinci-helper

3. Go to folder

cd /usr/bin

4. Run the app:

python3 davinci-helper
Traceback (most recent call last):
  File "/usr/bin/davinci-helper", line 5, in <module>
    from davinci_helper.main import main
ModuleNotFoundError: No module named 'davinci_helper'

Opening the app via the desktop shortcut = same result. Restarting the computer = same result.

Looking at the file davinci-helper, it's looking for the aforementioned davinci_helper.main python module, which I am unable to find anywhere on my system or in my python pkg manager.

[steckes]

The issue is that Fedora 43 switched to Python 3.14 and the package is still trying to install in Python 3.13.
You can install it manually, which works, but the functions are not ready for Fedora 43...

1. Install Build dependencies

sudo dnf install gtk4-devel libadwaita-devel python3-devel python3-pip python3-gobject

2. Download the files

wget https://github.com/H3rz3n/davinci-helper/raw/main/davinci-helper-2.4.7.tar.gz
tar -xzf davinci-helper-2.4.7.tar.gz
cd davinci-helper-2.4.7

3. Install

sudo pip3 install .

4. Copy data files

sudo mkdir -p /usr/share/davinci-helper
sudo cp -r data /usr/share/davinci-helper/
sudo cp -r locale /usr/share/davinci-helper/
sudo cp data/desktop/com.davinci.helper.app.desktop /usr/share/applications/
sudo cp data/desktop/com.davinci.helper.app.svg /usr/share/icons/hicolor/scalable/apps/
sudo mkdir -p /usr/share/metainfo
sudo cp data/desktop/com.davinci.helper.app.metainfo.xml /usr/share/metainfo/

5. Run

davinci-helper
