I have serious key problems that I am not able to solve. Apt keeps telling me that I do not have a key that I can verify I DO have. The normal answer to this issue is 99% of the time to apt-key add the missing key. However, that is NOT working on this machine and I dont know why. See below as the commands describe the problem better than I can here.

EDIT: DO NOT SUGGEST apt-key add as a fix. That is NOT the problem here. Take note below that the keys are ALREADY listed in apt-key list. Since the keys exist, I suspect the problem is in trying to read the key files themselves, (permissions maybe), but IDK where or what to look for to check that

I figured this out on my own! I was correct in my assumption that it was permissions. I took a shot in the dark and ran:

sudo bash
cd /etc/apt
chmod -R 755 .
apt-get update (At this point it began to work!)
exit

So if you have tried apt-key add and it doesnt work, maybe this will work for you. IDK how these permissions got jacked up, but this seemed to fix whatever it was.
