Hello, I just encountered the same issue. Thanks Alex for debugging and finding the reason: lxc-console attaches by default to tty 1 vs. but the template listens by default on tty 0.
Host is an up-to-date Debian buster, with packages lxc (1:3.1.0+really3.0.3-8) and lxc-templates (3.0.3-1). I created a Debian buster container like this: # lxc-create -n buster -t debian -- -r buster Then tried to open a console like this: # lxc-console -n buster Connected to tty 1 Type <Ctrl+a q> to exit the console, <Ctrl+a Ctrl+a> to enter Ctrl+a itself Nothing happened, so I specified tty 0 and it worked: # lxc-console -n buster -t 0 Connected to tty 0 Type <Ctrl+a q> to exit the console, <Ctrl+a Ctrl+a> to enter Ctrl+a itself buster login: Now I don't actually need lxc-console, I use lxc-attach which works great, but when I tested it it was weird that it didn't work with default options. Thanks!
