I’ve just upgraded from debian buster to bullseye on an arm64 platform.
For various reasons unrelated to this issue, I run debian with sysv init instead of the default systemd.
On this platform, I have an unprivileged container, also running a sysv init bullseye debian, which worked fine before the upgrade.
After the upgrade of the host to bullseye, the lxc-attach command starts to display this error:
terminal.c: lxc_terminal_create_native: 924 Permission denied - Failed to open terminal multiplexer device
Yet, I am connected to the container as expected.
I wonder if the above error is the symptom of something I have to take care of, or if I can simply ignore it.
Could someone explain me what it means and what I should do to get rid of it ?
