It's still got to be some library in the xcb library system. So far as I can see it's a Qt problem, not really a Leo one - although that doesn't help, does it? Just having them already installed isn't always enough. I remember one of my VMs had the culprit installed, but after I ran the installation command for it then Qt worked. I don't remember any details, though. I also recall that in one case the library name was different from the one or two that had been suggested in the error message. That time I lucked out with an Internet search.
Which distro is this, BTW? On Monday, July 22, 2024 at 10:48:32 AM UTC-4 [email protected] wrote: > Latest qt6-tools are Installed already. Installed qtutilities-qt6.
