How to copy files from PC to LXC?

[antamy]

I have LXCs created by the tteck scripts, with autologin to the console from Proxmox. I would like to copy files to the LXC from my Windows PC. I would normally use WinSCP to do that, however I don't know the root password. If I create a user in the LXC using adduser it does not allow me to set a password, failing with Authentication token manipulation error. How do I resolve this?

LXCs Install scripts have defaults set to NO when it comes to "allow SSH" at all. Here you will find all the steps to enable password connection (if you wish, you can also use an ssh-key):

The problem isn't in the ssh configuration, it's that trying to set or change passwords gives Authentication token manipulation error. That I do not know how to resolve.

passwd root
sed -i -e 's/#PermitRootLogin prohibit-password/PermitRootLogin yes/g' -e 's/^PasswordAuthentication.*/PasswordAuthentication yes/' /etc/ssh/sshd_config
ssh-keygen -A
systemctl restart sshd

for ssh

Should this be on the host as I get the error above about Authentication token manipulation error on the LXC when running passwd root?

no @ lxc: don't know what you have done in the past, I get the New Password dialog.
