<solved> Added Repository: now get an error message.

[chrism66]

I was missing the following repoistiry in my sources list:

deb http://debian.linuxmint.com/latest/multimedia testing main non-free

Now when I run the update manager and click the refresh button I get the following messsage:

W: GPG error: http://debian.linuxmint.com testing Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 07DC563D1F41B907

When I remove the added repository the message goes away. I have searched and tried many things too fix this message but it will not go away.

For help here is the output for $ inxi -Sr

sorry, a bit unclear, with the repos you posted in the end of your post you are getting that "missing key error"?

[chrism66]

Yes.

[zerozero]

what is the output of

Code: Select all

apt-cache policy debian-multimedia-keyring

[chrism66]

debian-multimedia-keyring:
Installed: (none)
Candidate: 2010.12.26
Version table:
2010.12.26 0
500 http://debian.linuxmint.com/latest/multimedia/ testing/main amd64 Packages

[zerozero]

Code: Select all

apt install debian-multimedia-keyring

Code: Select all

apt update

(now the error should be gone)

[chrism66]

Thanks zerozero! that fixed it.

[zerozero]

good
though it's strange because that pkg should be installed by default nevermind, the fix was easy.

Thanks zerozero! that fixed it.

This is what I get when I try to update the repositories, and I have the debian-multimedia keyring properly installed and working. I have also tried to import the GPG key from a working Mint Debian machine...

W: GPG error: http://packages.linuxmint.com debian Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 3EE67F3D0FF405B2
E: Release file expired, ignoring http://debian.linuxmint.com/latest/dist ... ng/Release (invalid since 59d 7h 8min 34s)

The affected repository is:

deb http://packages.linuxmint.com/ debian main upstream import

Why is such a simple thing, the GPG key for the repository, so IMPOSSIBLE to find on the Linux Mint website?? When I search for "Mint Debian pubkey" I get "not found, did you mean PUKE?"

Not very encouraging.

[zerozero]

Not very encouraging.

no need to
linuxmint-keyring is here http://packages.linuxmint.com/list.php?release=Debian (but should be in your repos as well)

Code: Select all

apt policy linuxmint-keyring
linuxmint-keyring:
  Installed: 2009.04.29

the other error (yes, you have 2 there)

E: Release file expired, ignoring http://debian.linuxmint.com/latest/dist ... ng/Release (invalid since 59d 7h 8min 34s)

Neglected to thank you for this good advice - am not a churlish lout, just occasionally lax...

Thx very much!
