Removed skype still have apt get update errors about skype

  • 772

I've completely purged Skype from ubuntu 20.04 since I kept receiving the following error whenever apt-get update and couldn't find a solution:

Err:4 https://repo.skype.com/deb stable InRelease                        
  The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 1F3045A5DF7587C3
  
  Reading package lists... Done
W: GPG error: https://repo.skype.com/deb stable InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 1F3045A5DF7587C3
E: The repository 'https://repo.skype.com/deb stable InRelease' is not signed.

Yet, I still receive the above error when apt-get update even though I've removed the public key, all Skype installs and Snaps.

What is going on?

apt

  2. 1F3045A5DF7587C3 key is no longer valid which can be removed using apt-key del command.

    Step 1: Delete the invalid key:

    sudo apt-key del 1F3045A5DF7587C3

    If anyone has Skype running but facing the signature verification error while running sudo apt update command then continue with the below steps.

    Step 2: Add a valid key:

    curl https://repo.skype.com/data/SKYPE-GPG-KEY | sudo apt-key add -

    Step 3: Run the below commands:

    sudo apt update

sudo apt upgrade

    This error should be removed now!
