it seems that the image contains device nodes, this cannot work when creating unprivileged containers -> use a different image or create them as privileged

please post in english (potentially via google translate or a similar service) - since these forums use english to reach as many users as possible.


Else - the error-message indicates that you try to restore the container as _unprivileged_, but if it contains devicenodes ( './var/spool/postfix/dev/random') this does not work. Restore as _privileged_ container.

(The standard-template for ubuntu-18.10 does work as unprivileged container (and already contains postfix))
