Nail/drill Cable trunking to concrete wall?

[AndersRenovering2023]

Hello,

I am planning to run about 20 m (total) of cable duct against a concrete wall (on top of existing moldings). Should I buy concrete nails and hammer or do I need to drill and screw?

Unfortunately, my wooden moldings are not wide enough to support the duct itself.

Glue?

There are no nails you can just hammer in, so a small nail plug (adjusted to the thickness of the list) is probably the best option.
