update error

hi, i tried to install a plugin and got an error.

Plugin: openmediavault-zfs 5.0.6

error #0:
OMV\ExecException: Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C.UTF-8; export DEBIAN_FRONTEND=noninteractive; apt-get --yes --auto-remove --purge remove openmediavault-zfs 2>&1' with exit code '100': E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem. in /usr/share/openmediavault/engined/rpc/pluginmgmt.inc:153

#5 /usr/sbin/omv-engined(537): OMV\Rpc\Rpc::call('Plugin', 'remove', Array, Array, 1)
#6 {main}

Can someone please explain me how I can solve the problem concretely?

Now it says this here

error #0:
