It seems not to be able to find the class jiconfont.icons.FontAwesome, even though the package was listed as installed and set up.
If further testing would be helpful, let me know - happy to assist.

@becker44a Thank you for the detailed info. It seems that jiconfont-font-awesome changed the package structure between 4.7.0.0 and 4.7.0.1. I'll check if I can workaround this issue.

@becker44a I updated the PPA packages today. Would you test it?

Just updated, Lightzone starts on Ubuntu Noble 24.04.01 LTS now.

Just updated, Lightzone started w/ no issues on Mint 22 VM. Launched successfully both from cli and gui menu. Loaded some images - operation appears to be normal.
