Is it possible you upgraded the kernel at the same time? Newer kernels add
a new capability (`CAP_CHECKPOINT_RESTORE`); Podman is reporting that your
container has this new capability. It seems like whatever Java library
Jenkins is using to contact Podman does not account for the fact that new
capabilities are occasionally added to the kernel, and is hard-failing on
this new cap it doesn't understand.
Thanks,

Wonder if anyone can tell me what changed with the API from version

We use the jenkins docker plugin to allow jenkins to connect to our Linux
nodes and spin up podman containers to run builds in.
up till now, everything worked fine. on a new Linux node, we ran an update
and it picked up the latest podman version from our RedHat Satellite
server. On the older Nodes, this is the version jenkins shows when using
the cloud "test connection" button from the cloud/template setup screen.
Version = 3.0.2-dev
on the new node to that has the newer version of podman,
newer version:
Version = 3.2.3
However, Jenkins can no longer spin up the containers.
here is the error jenkins provides when trying to start a container with
the newer version.:
Note: Disabled 21 sec ago due to error. Will re-enable in 4 min 38 sec.
Reason: Template provisioning failed.
com.fasterxml.jackson.databind.exc.InvalidFormatException: Cannot
deserialize value of type `com.github.dockerjava.api.model.Capability` from

the only thing that changed is the newer version of podman. seems like
maybe the API is returning some new information of the formatting of the
returned info has changed? any help or insights would be greatly
appreciated.
Thanks,
Rusty
