Apt-get update NO_PUBKEY error solution, I believe that many inexperienced people do not know what to do, so this paper summarizes the causes of the problem and solutions, through this article I hope you can solve this problem.

This problem will also appear in other versions of Ubuntu, in fact, there are more or less similar details errors in the online system templates of merchants, which are worthy of our attention and correction. Of course, this kind of problem is not really big, but it may require some search work to solve it.

The solution to the error of NO_PUBKEY returned by apt-get update

The code is as follows:

W: GPG error: http://security.ubuntu.com trusty-security Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 40976EAF437D05B5 NO_PUBKEY 3B4FE6ACC0B21F32

Run the following command to solve the problem

The code is as follows:

Apt-key adv-recv-keys-keyserver keyserver.ubuntu.com 3B4FE6ACC0B21F32

Apt-key adv-recv-keys-keyserver keyserver.ubuntu.com 40976EAF437D05B5

In fact, similar problems, no matter what Key is, just need to replace it with the same code to the location of the relative Key.

The return result of each command is similar

The code is as follows:

Executing: gpg-ignore-time-conflict-- no-options-- no-default-keyring-- homedir / tmp/tmp.w8njroYZkC-- no-auto-check-trustdb-- trust-model always-- keyring / etc/apt/trusted.gpg-- primary-keyring / etc/apt/trusted.gpg-- recv-keys-- keyserver keyserver.ubuntu.com 40976EAF437D05B5

Gpg: requesting key 437D05B5 from hkp server keyserver.ubuntu.com

Gpg: key 437D05B5: public key "Ubuntu Archive Automatic Signing Key" imported

Gpg: Total number processed: 1

Gpg: imported: 1

Then there should be no similar errors in apt-get update.
