命令说明了一切：
~> sudo snap refresh
All snaps up to date.
~> sudo snap install podman
error: snap "podman" is not available on stable but is available to install on the following
channels:
edge snap install --edge podman
Please be mindful pre-release channels may include features not completely tested or
implemented. Get more information with 'snap info podman'.
~> sudo snap install --edge podman
error: The publisher of snap "podman" has indicated that they do not consider this revision to be
of production quality and that it is only meant for development or testing at this point. As
a consequence this snap will not refresh automatically and may perform arbitrary system
changes outside of the security sandbox snaps are generally confined to, which may put your
system at risk.
If you understand and want to proceed repeat the command including --devmode; if instead you
want to install the snap forcing it into strict confinement repeat the command including
--jailmode.
~> sudo snap install --edge podman --devmode
podman (edge) 0.11.1.1 from Lokesh Mandvekar (lsm5) installed
~> podman
Command 'podman' not found, did you mean:
command 'pod2man' from deb perl (5.30.0-9ubuntu0.3)
Try: sudo apt install <deb name>
知道如何podman使用快照/为什么这不起作用？
