aptitute became non-working after installation of manual-compiled .deb Linux kernel

["Ebanutiy Ebanatik Ebanatovich" <ebanutiy.ebanatik.ebanatovich@gmail.com>]

I compiled Linux kernel package using make-kpkg --initrd
--revision=bitobor.1.1 kernel_image.
Then I succesfully installed it
(/usr/src/linux-image-2.6.23_bitobor.1.1_amd64.deb)
After that, synaptic & aptitude safe-upgrade became non-working:

E: I wasn't able to locate file for the linux-image-2.6.23 package.
This might mean you need to manually fix this package.

I tried to add the below to my sources.list but it wasn't helped so
I'm still unable to install any package. Could you help please?

deb file:/usr/src/ unstable main contrib non-free
