"Must be connected to a terminal error" with screen -x command on a Linux Container
Solution 1
I found a solution that works for same case(https://www.svennd.be/screen-in-lxc-attach)
Execute this
script /dev/null
Then you can run screen, et voila
Solution 2
This is happening mostly because of the reason that you must have
switched user
to the current terminal user using the command sudo su
or user changing command.
You will need to own the shell on which you are working.
You can do so by running this:
script /dev/null
.
Alternatively, You can restart the terminal session with the user(which was used when creating screen) and not coming to current user using switch user commands.
To know active screens :
screen -list

I am using Linux containers with Proxmox 4. When I am connected on an Ubuntu 16.04 container with:
pct enter <id>
I run a script with screen and try to watch the process running with:
screen -x <processname>
I got the error:
Must be connected to a terminal error
When I connect with:
ssh -t <user>@<container_ip>
It works, I can attach the display to the screen.
How can I use screen -x when I am connected with pct enter ?

JdeBP over 4 yearsThat does not explain what the cause of the problem is, though; it merely bodges around it with a pseudoterminal.

JdeBP over 4 yearsThis explanation makes no sense at all.
script
is not a command for owning a shell, andsudo
is unrelated to a lack of a controlling terminal because it does not adjust the controlling terminal. -
