podman random error - device busy / sandboxing

Post by rob153 » 2021/07/30 06:59:07

Hi all,

I'm running a rootless container, and whenever I try to restart it, on the first attempt to `podman restart` I get

Code: Select all

Error: slirp4netns failed: "ioctl(TUNSETIFF): Device or resource busy
WARNING: Support for sandboxing is experimental
child failed(1)
WARNING: Support for sandboxing is experimental"
Then, I run the exact same command again and it works on the second attempt. This currently prevents me from automating.

Does anyone have an idea what this error means?

I'd guess you've got an OpenVPN (or something similar with a TUN interface) on there. Perhaps try it without the tunnel?
