In an effort to get monitor mode working on any raspberry pi, I grabbed the 32 bit image, verified the published Sha 256, and installed it with dd from another raspberry pi, using an adapter that allowed me to plug a micro sd card into a USB slot. All this worked, I verified that I had a good partition table. Then I moved the chip into a previously working 3b, and booted it up.
Then I got it hooked to my wifi and it reset my clock properly.
Finally, I did "sudo su" and "apt update".
This step failed. The message I got was that http.kali.org did not have a release file, that I could not update from such a repository securely, and therefore could not issue an apt update.
So this stops me from trying monitor mode on this platform at all.
Is this a known bug or an I supposed to point to a different repository?
