Is it related to the GUI? I am still able to run the server and access the web portal through browser.

Hello, I hope this is the right place to post this. I have created a similar post over on Mobile Read as well. https://www.mobileread.com/forums/showthread.php?t=359250&highlight=lxc

Issues installing on a Proxmox LXC.

Hypervisor: Proxmox 8.1.4
LXC OS: Ubuntu 22.04.04 fresh install (Headless)
LXC Storage: 25GiB
VCPU Cores: 2
Memory: 4096 MiB
Swap: 0

Hello, I am having trouble getting Calibre to install and run for me. I am on LXC 15 or 16 now, as I have tried multiple guides, and install methods, but none seem to work. All roads lead to the same issue.
