As reported by [1], the lxc test is broken since lxc >= 4.0.11.
A patch was added to lxc 4.0.11 to use the new mount api for devpts
setup [2] but the fall back code doesn't work when this new mount
API is not supported. This API was added in kernel 5.6.
(kernel 5.5)
DEBUG conf - conf.c:lxc_setup_devpts_child:1682 - No new devpts instance will be
mounted since no pts devices are required
lxc-start lxc_iperf3 DEBUG conf - conf.c:lxc_setup_dev_console:1966 - Cleared
all (0) mounts from "/dev/console"
lxc-start lxc_iperf3 ERROR mount_utils - mount_utils.c:mount_at:661 - No such

lxc-start lxc_iperf3 TRACE conf - conf.c:lxc_setup_dev_console:1990 - Setup

Bump the kernel to the current LTS 5.15.38 version that fully support the
mount API needed by lxc.
