to re-create the issue,
1 clean install of impish
# probably need sudo or be root for the following
2 boot into impish and install all updates
3 apt get install "lxc lxcfs lxc-utils lxc-templates lxctl"
4 lxc-create -n test -t ubuntu
5 lxc-start test
6 lxc-console -n test
# the above command FAILS to get a response, HOWEVER:-
7 lxc-console -t 0 -n test
# WORKS, only tty0 works in the container
==============================================================
THE CAUSE OF THE ISSUE!!
==============================================================
Previous to impish there are systemctl services to tend to all tty[1-4] and the
console (tty0)
eg, on Focal Fossa, in the container :-
systemctl | grep tty # gives
dev-lxc-tty1.mount loaded active mounted /dev/lxc/tty1
dev-lxc-tty2.mount loaded active mounted /dev/lxc/tty2
dev-lxc-tty3.mount loaded active mounted /dev/lxc/tty3
dev-lxc-tty4.mount loaded active mounted /dev/lxc/tty4
console-getty.service loaded active running Console Getty
container-getty@0.service loaded active running Container Getty
on /dev/pts/0
container-getty@1.service loaded active running Container Getty
on /dev/pts/1
container-getty@2.service loaded active running Container Getty
on /dev/pts/2
container-getty@3.service loaded active running Container Getty
on /dev/pts/3
system-container\x2dgetty.slice loaded active active
system-container\x2dgetty.slice
system-getty.slice loaded active active
system-getty.slice
getty.target loaded active active Login Prompts
================================================================================
In impish, in the container,
systemctl | grep tty # gives
dev-lxc-tty1.mount loaded active mounted /dev/lxc/tty1
dev-lxc-tty2.mount loaded active mounted /dev/lxc/tty2
dev-lxc-tty3.mount loaded active mounted /dev/lxc/tty3
dev-lxc-tty4.mount loaded active mounted /dev/lxc/tty4
console-getty.service loaded active running Console Getty
system-getty.slice loaded active active system-getty.slice
getty.target loaded active active Login Prompts
===============================================================================
As can be seen, there are no daemons started for any of the tty[1-4]
consoles apart from console getty service.
The command lxc-console doesn't seem to default to tty0, so it picks a
console that doesn't have a daemon to service it. Specifying tty0 (-t
0) makes it work. This seems to be a regression from the original,
Focal Fossa as well as Hirsute Hippo
