super sleep deprived but coherent. Hopefully not being a complete dope and this laptop has caused me some trouble before. I added the keys from Neuroscience Debian just yesterday no sweat on another machine. Not sure if it's the lack of sleep or what but I'm receiving an error I can't mentally process right now. Thanks for all the help.

Following the instructions on this link: http://neuro.debian.net/ and selecting "Ubuntu Xenial (16.04), USA California Server, I receive this from the instruction outputs:

" wget -O- http://neuro.debian.net/lists/xenial.us-ca.full | sudo tee /etc/apt/sources.list.d/neurodebian.sources.list

That's fine and dandy, problem is the key ain't checking out:

"sudo apt-key adv --recv-keys --keyserver hkp://pool.sks-keyservers.net:80 0xA5D32F012649A5A9
Executing: /tmp/tmp.ZGsHDOyuEZ/gpg.1.sh --recv-keys

gpg: Total number processed: 0

I tried clearing any existing keys and re-signing, updating and rebooting. Not a weird cache issue and not a lost packet error. Thanks again for any assistance.

  • sounds like their key doesn't exist in the keyservers, or you've got something odd going on? Typically this isn't solvable by end-users, and needs to be handled by the people publishing the specific software. – Thomas Ward Aug 22 '17 at 2:16
  • Ok thanks Thomas, I wasn't sure what I could possibly be doing wrong... If there's any info I can provide let me know. – Tmanok Aug 22 '17 at 3:13

you could also just fetch the key from the neurodebian website directly... see http://neuro.debian.net/faq.html "What means “The following signatures couldn’t be verified...”?"

  • Hi Yaroslav, I was away for some time and my network turned into chaos. I will re-check whether this answer is correct. However on another machine off site I was able to install without any issues- perhaps the key has been fixed or perhaps this is a device specific issue. I will update you within the next few days. Thanks for your patience. – Tmanok Aug 29 '17 at 7:00
  • yes, in general fetching the key from public servers should work. But some times there are hiccups from the overloaded servers etc. That is why we also provide that key as a simple download (pointed in the FAQ) – Yaroslav Halchenko Aug 30 '17 at 13:42
