This is how my Vivitar lens looks like. Is it necessary to cut something of?
As Just1MoreDave said you can try to unscrew the dark grey inner ring thing.
It works without it and that is what hinders it from attaching to the house proper.

Your image is so small I cant really see but in my case there was just 2 small screws to remove and then lift that grey/black aluminum ring of.

Maybe it is easier to damage the lens/camera without that ring? Maybe not.
I prefer to still have it, just in case, even if I had to spend 5 minutes modifying it.

You are right, there are two small screws. I`ll try just unscrew it instead of surgery. Thank you very much for your help guys

why are you removing it? I have an old Vivitar 75-300 with the same aperture lever protector, it works just fine as is.

although the optical quality is really bad (soft and very low contrast).

Those lenses were made for Pentax film cameras. The DSLR's are built different in the mirror box area. Third party film camera lenses are not guaranteed to fit, only Pentax lenses are.
