Getting tasks like this one.

No clue what to make of this.
Debien 10 on an i7-4770.
Have ran the following as outlined.
sudo sed -i '$ a\kernel.unprivileged_userns_clone = 1' /etc/sysctl.conf
sudo sysctl -p
Still getting user namespace errors nonetheless, as well as the above.
Recommendations appreciated.

Have a look at this thread.
