I installed on QNAP LXC Debian (from ready to use package).
Whe I started, I can access to it via some virtual console - it is atomatically logging as root (not asking for password).
I changed root password via passwd, created new user and installed SSH server.
I am able to login via SSH to server but I can't use "su". It shows that password is incorrect.
I can't also login via SSH as root.
I don't know even what I can show to help you? What is this LXC debian image changing to standard Debian version?
Something in PAM? I don't know how it works and what file I can show.
Code: Select all
root@debian-buster-1:~# cat /etc/issue Debian GNU/Linux 10 \n \l
