Failed to decode the keys ["machine"] from "/usr/share/containers/containers.conf"

After upgrading to 0.46.0, whenever I use podman commands I receive the following WARN messages:

WARN[0000] Failed to decode the keys ["machine"] from "/usr/share/containers/containers.conf".
WARN[0000] Failed to decode the keys ["machine"] from "/etc/containers/containers.conf".

Did you update your containers.conf?

I'm not sure what you mean.
I upgraded the packages:
pacman -Syu

Same issue here. A [machine] section is present in "/etc/containers/containers.conf" and "/usr/share/containers/containers.conf" (created by Arch).

[machine]
# Number of CPU's a machine is created with.
#
#cpus=1

# The size of the disk in GB created when init-ing a podman-machine VM.
#
#disk_size=10

# The image used when creating a podman-machine VM.
#
#image = "testing"

# Memory in MB a machine is created with.
#
#memory=2048

# The [machine] table MUST be the last entry in this file.
# (Unless another table is added)
# TOML does not provide a way to end a table other than a further table being
# defined, so every key hereafter will be part of [machine] and not the
# main config.

Is this enough of configuration?

/edit: right now I "resolved" it by commenting the table header #[machine].

Yes, this means that they are shipping a newer version because we have released a newer version of containers-common, but podman 3.4 has not been released, which should understand the new format. For now you can safely ignore the error. or edit the containers.conf file to remove the stanza. Or wait for podman 3.4 to get released.
Either way this is not an upstream podman on common issue.
