Exterior wall of brick and aerated concrete, what should I have on the inside?

[xl15]

I am renovating a room on the upper floor of an old farm. The outer wall consists of brick and 10 cm light concrete. Plastered and painted on the outside with no air gap in the construction. The previous wall covering was about 2 cm thick slats nailed into the light concrete and then a layer of Tretex. No sill paper or similar between wood and light concrete. Everything dry and fine though.

The wall will be wallpapered and the question is whether I should make a similar construction or if I should plaster the wall with, for example, gypsum plaster? Or glue up drywall panels?

How do people usually do if they have an interior wall made of aerated concrete?

Now, 3.5 years later, I can report that what I did worked. Since it was dry and nice on the wall when I tore it down, I simply glued up drywall panels with plaster. No air gap or anything. No moisture problems and the wallpaper is still there 3 years later ✌️
