LuCI LXC Containers not is working

Software SW bugs discussion
1

I have installed the next packages:

# cat /etc/updater/auto.lua
– A file with auto-generated Install commands. Do not edit.
Install “6in4”
Install “block-mount”
Install “kmod-ata-mvebu-ahci”

And next package groups:

# cat /etc/config/updater 

config pkglists 'pkglists'
        list lists 'base'
        list lists 'cacerts'
        #list lists 'luci-controls'
        list lists 'lxc'
        #list lists 'nas'
        #list lists 'netutils'
        #list lists 'shell-utils'

config override 'override'
        #option branch 'stable-new'
        option disable '0'

When I go to LuCi LXC Containers and try to create one, it is not listed “Available Containers” and it is no created:

# ls -la /srv/lxc/
drwxr-xr-x 1 root root 0 Dec 9 15:09 .
drwxr-xr-x 1 root root 6 Dec 9 14:06 …

“/srv/lxc/” is a mount point for my mSATA:

# mount | grep -i sda
/dev/sda2 on /srv/lxc type btrfs (rw,relatime,ssd,noacl,space_cache,subvolid=259,subvol=/lxc)

Try creating it from command line:

lxc-create -t download -n container

It should display any errors it runs into.

Output:

# lxc-create -t download -n server

So it looks like you have only busybox tar and not a real tar. Install tar and it should work and I’ll fix dependencies.

After install “tar” all is working without troubles. Please, consider add “tar” to package group “lxc” or patch BusyBox.

I don’t sure if this can help:
