Unable to scan within a container that has access to an immutable OS

[Ricky-Tigg]

Hello, I am probably not making a mistake in thinking that the use of this program is not incompatible within an OCI-type container that has access to an immutable OS host.

Immutable OS host

$ hostnamectl | sed -n '8p;10p' | awk '$1=$1'
Operating System: Fedora Linux 43.20260224.0 (Silverblue)
OS Support End: Wed 2026-12-02

Container

OCI-image from which the container was created

$ podman images --format '{{.Names}} {{.Size}} | {{.IsReadOnly}}' | grep toolbox
[registry.fedoraproject.org/fedora-toolbox:latest] 2.11 GB | false

Entering the container with toolbox enter fedora-toolbox:latest.

Commands executed within the container

That would be the root of the following
non-existing paths. Waiting more than ten minutes does not affect the operation successfully.

⬢ [...@toolbx ...]$ maldet -a /home/$USER | sed '1,5d'
public scanning is enabled (scan_user_access=1) but paths do not exist, please contact your system administrator to run '/usr/local/bin/maldet --mkpubpaths' or wait for cron.pub to execute in ~10 minutes.
