My update manager tells me that it "could not refresh the list of updates". I tried to solve it by doing like in this post viewtopic.php?t=231516#p1226233
When I update the cache I get this message. If I just close it and try and update my update manager, I get the same message.

Code: Select all

W: GPG error: http://dl.google.com/linux/chrome/deb stable Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 6494C6D6997C215E
W: The repository 'http://dl.google.com/linux/chrome/deb stable Release' is not signed.

I guess it has something to do with google chrome and uninstall it only to continue to have the same message. When I search for chrome files I get over 700 hits and many of them are locked folders simply called 'chrome'.

I have know idea what this means and what to do about it.

Could someone please help me solve this and maybe make me understand what happened?

Thank you!

I'm seeing the same thing. (I installed google chrome via that repo)
As for what happened, it's tough to say. Perhaps their key expired.

Open a Terminal and copy and paste this into it,

Code: Select all

sudo apt update

Enter your password (It won't look as though anything is typing) and press Enter.

When it's finished, close the terminal (press the X or input Exit).

Then retry your Update Manager.

Should be refreshed now.

Thank you for answering, but I still get the same error, this time in the terminal window though.

Do you have an active internet connection? Or is it just the google repo that is not available?

Try

Code: Select all

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 6494C6D6997C215E

Then refresh the list of updates or do

Code: Select all

sudo apt-get update

It can also be fixed with

Code: Select all

wget -q -O - https://dl.google.com/linux/linux_signing_key.pub | sudo apt-key add -

This solved my Google Chrome issue but I am still have the same problem with OpenVpn.

I am in the process of researching how to update the authentication key but so far no luck.

W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: http://build.openvpn.net/debian/openvpn/stable xenial Release: The following signatures were invalid: KEYEXPIRED 1501828379 KEYEXPIRED 1501828379 KEYEXPIRED 1501828379
W: Failed to fetch http://build.openvpn.net/debian/openvpn ... elease.gpg The following signatures were invalid: KEYEXPIRED 1501828379 KEYEXPIRED 1501828379 KEYEXPIRED 1501828379
W: Some index files failed to download. They have been ignored, or old ones used instead.

I'm going to ask a very critical question about this solution.

what does the command do:

Code: Select all

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 6494C6D6997C215E

Why do I need to update the keys on this app?

Are you part of a nationally sponsored intelligence system?

Posted: **Sun Aug 06, 2017 7:31 pm**

Google Chrome had their key expire. It is that simple and I don't work for any intelligence agency so you can remove the tinfoil hat.

It also seems as if the OpenVPN authentication key has expired - any guidance as to how to update it will be appreciated.

Please direct us to Chrome documentation that provides the updated key and the expiration notice.

Hi "majpooper", & Anyone Else getting the OpenVPN and Google Expired keys,

I.) FYI: Google Chrome Linux information link
https://www.google.com/linuxrepositories/

II.) To Update or fix the OpenVPN expired key, open a console terminal prompt, and copy and paste each line below one at a time. Info came from link below.
https://community.openvpn.net/openvpn/w ... twareRepos

Code: Select all

sudo wget -O - https://swupdate.openvpn.net/repos/repo-public.gpg|apt-key add -

OR

Code: Select all

sudo -s

Code: Select all

wget -O - https://swupdate.openvpn.net/repos/repo-public.gpg|apt-key add -

Code: Select all

exit

Then, do an update

Code: Select all

sudo apt-get update

Hope this helps ...

THX much

I tried reinstalling OpenVPN and used the commands you show from the OpenVPN site with no joy.

However I found the solution below and it fixed it rooting around - sorry I did not bookmark or copy the URL but it was a Linix Mint site . . . . ? ? ? ? ?

sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com `sudo apt update 2>&1 | grep -o '[0-9A-Z]\{16\}$' | xargs`

Hi "majpooper",

You are welcome...

Those instructions I gave were for updating the "openVPN" security key to stop getting messages when updating your software sources in the Mint Update Manager or from the console terminal command line (sudo apt-get update), not for installing or updating their "openVPN" software. Your command in your last reply is not from the developers of the "openVPN" software.

After running the commands I gave before, If you still were getting messages, then run the command below to remove their expired key.

Code: Select all

sudo apt-key del E158C569

For instructions on installing a current version of "openVPN" software, or updating it, which is a great thing to do if you use VPN's, see the link below because their instructions from the web link I provided are a little cryptic.

Is it possible to install the latest openvpn on 17.3 without breaking everything[SOLVED]

Hope this helps ...
