bwrap and flatpaks inside Proxmox 8 LXC

[rcarmo]

I’ve been trying to get flatpak (which uses bwrap) to work inside an unprivileged LXC container in Proxmox 8. That particular container used to work fine under LXD (with LXD’s nesting), but LXC clearly manages things differently.

I have been trying to work around it using apparmor and hit upon the discussion at [Question] bwrap in LXC · Issue #362 · containers/bubblewrap · GitHub, but clearly Proxmox’s LXC has some nuance that I cannot pin down.

Does anyone here have any hints/experience with this issue? I need to be able to run RDP desktops inside LXCs (for my own use) and flatpaks are a must these days.

(running VMs is not an option due to resource constraints, and my former LXD setup did this with ease)

Thanks!

Same problem here, did you managed to solve it?
Thanks!

No. I began by setting up a VM on a slower machine in my cluster, but later I just gave up and set up LXD on bare metal Ubuntu and using rclone to set up backups. LXD _just worked_ and I honestly don't know how--perhaps the answer is in better apparmor defaults, but either way Proxmox engineering should take a look at this...
