Podman pull failures – Ensure the host has network access and the target
image reference is valid. Review Podman's stderr output for registry errors.
Missing execution backends – Install bubblewrap or proot to avoid
requiring root privileges for chroot. On Fedora, for example, run
dnf install bubblewrap proot.
Permission errors – Use a writable store directory. The defaults point to
/var/tmp, which typically supports world-writable storage.
