I run a Omada Controller LXC on Proxmox, currently at version 5.14.32.2 (Stable), if I try & upgrade to V 5.15.6.7 Build 20241128140044 I get the error: -

Reading package lists... Done
Building dependency tree        
Reading state information... Done
Reading state information... Done
This package is uninstallable
Dependency is not satisfiable: mongodb-server (< 7.1.0)|mongodb-10gen (< 7.1.0)|mongodb-org-server (< 7.1.0)

If I try and upgrade mongodb I get this: -

Reading package lists... Done
Building dependency tree       
Reading state information... Done
mongodb is already the newest version (1:3.6.9+really3.6.8+90~g8e540c0b6d-0ubuntu5.3).

Any ideas what I'm doing wrong?

Cheers
