Lxc with proxmox to use a LXC gui container

LXC
1

Hello,

I’m testing proxmox and its ability to create LXC container.

I tried to install ubuntu mate from an LXC container with template of ubuntu 16.04. It seems so that all pre existing template are just text and we have to install ourself gui interface.

For example, this is the error I have when I try to install it with apt-get install ubuntu-mate-desktop.

But I have dependances errors :

Is it possible to have this working perfectly on lxc or it’d not recommended?

Thanks

It’s possible to install and run GUI apps from a container, but you’d usually install individual software rather than an entire desktop. That’s unless your goal is to offer a VNC/NX type remote desktop environment, in which case installing the entire desktop does make sense.

Here it looks like package installation is failing due to the bluetooth service failing to start. You’d need to look into that particular systemd unit and either override it or mask it which should let you go a bit further.

In this blog post: http://ghanima.net/doku.php?id=wiki:lxc:guiappsinlxd

scroll down (or search) for the section that begins with: bluetoothd error (probably unnecessary)

Shaun describes a work-around for the bluetooth that you might try.

I’ve seen those same errors if I try to install a full desktop in an “unprivileged” container. I never see them in a “privileged” container though.
