Signatures Couldn’t Be Verified: Public Key Not Available

Asked By 0 points N/A Posted on -

I am running Linux Mint 12 with MATE. I just added WINE PPS following the instructions and downloaded the Wine package from the winehq download page. However, when I try to refresh in synaptic, an error occurred. And then another warning pops up on Wine 1.3 installation stating that the package cannot be trusted. I want to know, can I just get rid of the warning and continue with the installation? Any ideas? Thanks.

An error occurred

Signatures Couldn’t Be Verified: Public Key Not Available


This is a common error while installing an application or updating a package and solution is very simple. This error means the public key has not been added.

To resolve this issue, open the terminal by pressing Ctrl+Alt+T and use the following command in the terminal:

sudo apt-key adv –recv-key –keyserver 5A9A06AEF9CB8DB0

After adding the missing Public key run the following command one more:

sudo apt-get update

Henceforth you should not face this problem anymore.
