apt-get update GPG error: NO_PUBKEY

Question

Hello NETGEAR engineers,&nbsp;I recently try to update the package lists on RN214 running ReadyNasOS 6.6.0 version. and got the following error:&nbsp;It seems that apt.readynas.com is NOT working, and egnyte-cdn.egnyte.com requires a GPG pubkey.&nbsp;Will NETGEAR still allow user to modify/update/install packages from apt.readynas.com? I've searched through the forum and could not find any post regarding this issue.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

FWIW, apt.readynas.com works for releases 6.8.0 and later.&nbsp;&nbsp;http://apt.readynas.com/packages/readynasos/dists/6.8.0/updates/binary-armel/Packages.&nbsp;&nbsp;
&nbsp;
If you browse for releases before that, you get a forbidden error.
&nbsp;
So one option might be to upgrade your firmware.

The NAS does not run from flash, and I doubt you managed to remove anything from the gzipped OS version in flash. So, all you should need to do is an OS re-install, which will refresh the running copy on your drives from the copy in flash. You can accomplish that from the boot menu. Just be sure to not accidently do a factory default, which will wipe your data. Note that this will also set the password back to the default password, disable volume quotas (if you have them enabled), and set the LAN to unbound and DHCP (if you have them set to somehting else). So, you just need to go back and reset your password and options.

Why you would continue to run an ancient version of the OS is yet another question; but it's your choice.

Thank you&nbsp;StephenB for replying. It's good to know that Netgear does NOT maintain the packages avaiable for each ROM versions!&nbsp;I accidently deleted one of the package "readynas-agent", which is preventing admin web interface to be loaded.

I wonder if this is anyway to get this packages for ROM 6.6.0? or Will the package be recovered, if I re-flash the rom 6.6.0 again?&nbsp;I searched on the forum the way to flash through ssh is:# echo /root/ReadyNASOS-6.6.0-arm.img &gt; /etc/.flash_updateIs there anything else I shoudl pay attention to? (of course I will do back up first). Thank you all for your advices and suggestions in advance.&nbsp;

Thank you Sandshark and StephenB for your reply!&nbsp;I spent several days backing up all the files, and about to perform an OS reinstallation. After a clean reboot, I am able to get admin web interface back! Now, I recalled that after I removed "readynas-agent" package and had an power failure (my UPS did not perform an graceful shutdown successfully).&nbsp;When I get to the NAS through ssh, the apt.readynas.com is magically working, but egnyte-cdn.egnyte.com still not, unfortunately.&nbsp;I immediately updated the full package list and downloaded the missing package:&nbsp;# apt-get update
# wget http://apt.readynas.com/packages/readynasos/dists/6.6.0/main/pool/r/readynas-agent/readynas-agent_1.0_armel.deb--2021-04-16 15:02:12-- http://apt.readynas.com/packages/readynasos/dists/6.6.0/main/pool/r/readynas-agent/readynas-agent_1.0_armel.debResolving apt.readynas.com (apt.readynas.com)... 99.84.210.101, 99.84.210.79, 99.84.210.23, ...Connecting to apt.readynas.com (apt.readynas.com)|99.84.210.101|:80... connected.HTTP request sent, awaiting response... 200 OKLength: 7994 (7.8K) [application/x-debian-package]Saving to: ‘readynas-agent_1.0_armel.deb’&nbsp;It will be nice if packages could be extracted from the ReadynasOS rom files, and I did a quick search through the forum, found that it's not allowed due to some proprietary code.&nbsp;Lesson learned here is:back-up the packages with the correct version number before remove themRAID is NOT a backup, should maintain a real backup regularly!Do NOT touch/change any working system:smileyhappy:It still remains a mystery to me why a power failure killed the admin web interface. I am happy to the current results, and Thank you all for your supports!&nbsp;&nbsp;
