It’s been a wile that @nachoparker has published a LXD of NCP.
In theory, that should make it possible to install NCP on Proxmox as a CT.
However, things are more complicated than they seem. To my knowledge, there is nobody who has succeeded to install it on Proxmox (mid-December 2021).
So let’s try to solve this together. If we succeed, I will write a documentation and add it to Getting started with NextCloudPi on Proxmox and the official NCP Docs.
The first problem is that Proxmox needs .tar.gz the LXC is .tar.bz2
This means it can not even be uploaded.
Workaround
- Decompress
NextCloudPi_LXD_10-08-21.tar.bz2and compress it as .tar.gz
I found someone with a related issue on the Proxmox Forum and used the advice given to compress the image as .tar.gz
After downloading the NCP_LXD image …
~]$ cd /home/mnj/Downloads/
Downloads]$ ls -l
drwxr-xr-x 2 mnj mnj 4096 30. Nov 21:17 NextCloudPi_LXD_10-08-21
Downloads]$ mkdir temp-convrt
Downloads]$ cd temp-convrt/
temp-convrt]$ tar xpf /home/mnj/Downloads/NextCloudPi_LXD_10-08-21/NextCloudPi_LXD_10-08-21.tar.bz2
temp-convrt]$ ls -l
drwxr-xr-x 3 mnj mnj 4096 17. Dez 23:36 backup
temp-convrt]$ sudo tar cpzf /home/mnj/Downloads/ncp-lxd4proxmox.tar.gz -C backup/container/rootfs/ .
Note: You need to pack backup/container/rootfs/ . if you try to directly pack the backup/ directory, you will get the following error when trying to install on Proxmox:

TASK OK
It could be that you also succeed if you pack: backup/container/ . I believe I tried that and also succeeded to install.
It seems to me, Proxmox does not search the directory. But actually, I have no idea what the issue is.
Packed as .tar.gz the ncp-lxd template can now be uploaded
with this output:

TASK OK
And it can be installed successfully,
with the following output.

The second problem ist that if you start the CT Container and go to the initialization page with your browser, you will be greeted with a promising:
“Warning: Potential Security Risk Ahead”
but subsequently, you will be disappointed with a:
Forbidden
You don’t have permission to access this resource.
It is possible to use the >_shell and even reach ncp-config
It will ask to update but seems to fail. Maybe due to ncp not yet being initialized?

Basically, this is where I’m stuck for now.
Do you have any ideas how to see what the reason is that I get the permission error?
I can’t login through the console, and the web splash page isn’t showing when I browse to the IP of the container.
(i.e Proxmox itself, or maybe just VM Hypervisors & Docker containers), at least not yet. They can be quite difficult to understand after all, I don’t know everything about them myself either
