I had FLUKA and Flair already installed and working fine in my laptop, with Fedora42. I did the upgrade to Fedora43 and when I try to launch Flair simply nothing happens.
I’ve tried to launch Flair form the term and this is the result:
The problem is not with a specific project. Even if I try to launch Flair alone it did not work.
I have continued to try, and I saw that if I use
flair -i /usr/local/flair.ini
from the terminal, it is working. Note that in upgrading the operating system I did not changed anything in the configuration, nor environmental variables, nor the position of the Flair.ini, that is alwais in ./config under my Home. In the configuration of Flair the Fluka directory is not set. If I set it manually, I can load my existing projects and run them. But I am not able to “consolidate” this. Every time I have to launch again Flair from the terminal, need to accept the Licence and set again the Fluka dir. The plots work, but if I try to load the Geometry this make everythying crash.
I wonder if there is a problem with the latest Gnome version not supporting anymore X11, but it is not clear to me why configurations that were pre-existing now are not working.
Dear Mario,
it’s a FC43 bad surprise linked to a (hopefully temporary) python issue.
For the time being, install python3.13 and point the PYTHON variable to it.
Please let us know if problems persist.
good to know that you confirm this. It is a useful information for all Fedora users (like me) that it could be better to delay a bit the upgrade to F43. Personally, I will continue to use FLUKA on my older (but still valid) laptop, waiting for a solution.
