LAB 3.2 LXC - setfacl

Battogtokh

Hello,

I am working on Lab 3.2 and on the page 3 of the lab document, we need to set the access control list on ~/.local directory.

Do we need to create this directory, please? I cannot find if we created ~/.local directory. Can you please advise?

Hi @Battogtokh,

How did you provision the lab environment, what hypervisor or cloud are you using (if at all) and what guest OS? Also, is all ingress traffic allowed to your VM per the instructions in the first chapter?

As a last resort, we can disable the validation to help you move past this step:
lxc-create --name unpriv-cont-user --template download -- --no-validate

Ok. It looks like the .local directory is created itself after running the lxc-create command. I can set an ACL now.

But I am stuck at running this command now. Can you please advise?
I don't understand why the optional argument --keyserver is not recognizable.

student@lfs253:~$ lxc-create --name unpriv-cont-user --template download --keyserver keyserver.ubuntu.com
lxc-create: unrecognized option '--keyserver'

Hi @Battogtokh,

The following syntax may help:

lxc-create --name unpriv-cont-user --template download -- --keyserver keyserver.ubuntu.com

Hi @chrispokorni, thank you very much for your reply.
Mine is showing this response.

Thank you very much. --no-validate works. I am running the Ubuntu Server edition v20.04 VM on VMware ESXi host. The server has access to internet and every other lab works, except the lxc one. The --no-validate made it working. Thanks again.

Hi,

to give further informations here if someone walks in later with this problem. I have used Ubuntu 18.04 here and had this problem also. I manually created the ~/.local directory before running the lxc commands. After that I created the acl and ran the lxc-command with the --no-validate option.

Have a nice day
