Why would you pain’t over The Wallpaper? Take the time to strip it...it can be a fun job,not odious.

Remove knobs, it's easier to take the doors off to paint, sand all doors and drawer front. Clean the rest of the brown laminate with a good de-creaser, sand lightly, paint. If you want to paint a real light color on the brown parts, use primer, let it dry, sand lightly, vacuum, paint. If the wallpaper is still good connected to the walls, wash it with soap and water, I would use a roller to paint it, looks good, I have done it. If there are loose parts of the wallpaper, glue it after it is washed and dried. My kitchen was very dark brown, very depressing, I have paint all cabinets a very light color lilac, walls and ceiling white, it is a pleasure to be in the kitchen. Good luck to you!!

I've successfully painted over floral and striped wallpaper by 1) dusting off the whole wall with a dry Swiffer on a mop handle; 2) applying (mostly by roller) 2 coats of oil-based Kilz; 3) 2 coats of a good acrylic latex paint (with primer included.) Very good look with many many compliments. Walls were NOT Sized before papering. Saved LOTS of time and patching/sanding - Good Luck!

Best to remove the wallpaper. Moisture in the paint can cause the paper to bubble or unglue in areas.

Make sure they are clean and dry. Remove the doors and hardware. Mark the doors and cabinets with tape where they go. Lightly sand the doors and cabinets to remove any gloss and roughen the surface for paint with 120- to 220-grit sandpaper. Use a tack cloth or damp rag to remove dust after sanding. Prime with a stain blocking primer like Zinsser 123, KILZ,or BIN and have it tinted to the color of the top coat. This will prevent dark or stained surfaces from showing through the top coat. Acrylic, or water-base, paints are low-fume and clean up easily with water. Alkyd, or oil-base, paints require good ventilation because the paint contains solvents that can irritate your lungs and make you feel sick. Alkyd options require mineral spirits for cleanup, but they provide a hard, durable paint finish. Whichever you use, buy the best-quality paint you can afford for a lasting kitchen cabinet finish. Seal with at least three coats with a water based polyurethane. Use a small foam roller and foam brush for a smooth finish.

We stripped the wallpaper in the bathroom and it was a disaste! The wall wasn’t primed under it, just 1990’s drywal!

Thank you

my painters actually painted right over my wallpaper because it was too hard to remove. A good primer base and then your top-coat. No problems. As far as the cabinets make sure you lightly sand and again, a good base primer then usually enamel is recommended for cabinets but I'm sure you can use a good latex paint.
