Deinstallation von Heroku CLI brach apt in Ubuntu

Question

Ich benutze Ubuntu 16.04 und ich habe die Anweisungen, Uninstalling the Heroku CLI folgen.

sudo apt-get remove heroku 
sudo apt-key del <Heroku's key from 'apt-key list'> 

habe ich heroku-toolbelt Paket nicht deinstallieren, da es nicht gefunden wurde. Auch /etc/apt/sources.list.d/heroku.list existiert nicht.

Problem tritt auf, wenn ich nachher sudo apt update und sudo apt dist-upgrade mache.

Err:7 https://cli-assets.heroku.com/branches/stable/apt ./ InRelease 
The following signatures couldn't be verified because the public key is not available: NO_PUBKEY C927EBE00F1B0520 
...

W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: https://cli-assets.heroku.com/branches/stable/apt ./ InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY C927EBE00F1B0520 
W: Failed to fetch https://cli-assets.heroku.com/branches/stable/apt/./InRelease The following signatures couldn't be verified because the public key is not available: NO_PUBKEY C927EBE00F1B0520 
W: Some index files failed to download. They have been ignored, or old ones used instead. 

Ich denke, apt-key del brach die apt aber ich wollte ganz Heroku-CLI deinstallieren (die den Schlüssel enthalten), da ich nicht mehr benötigen.
