I'm experiencing the same issue as of today. I'm running KasmVNC as part of a https://github.com/selkies-project/docker-nvidia-glx-desktop docker container.

@mmcclaskey thank you! I've got it installed and running now, I'll let you know if the issue returns.

@mmcclaskey I'm sorry, but as a downstream container maintainer, when will the new release be out? It's three and a half months after Ubuntu 24.04 came out and at least KasmVNC can use a release.

[mmcclaskey]

A new release will be out in the approximately 1 to 3 weeks.

Thank you. @mmcclaskey
