Vagrant reload --provision Error

Hi team, i was working with vagrant and it was all ok.
But yesterday i have this error when i run Vagrant reload --provision


I think that is the followings lines:
homestead: Err:10 Index of /pub/repos/apt/ bionic-pgdg Release
homestead: 404 Not Found [IP: 217.196.149.55 80]
homestead: Err:11 https://cli-assets.heroku.com/apt ./ InRelease
homestead: The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY 536F8F1DE80F6A35
homestead: Reading package lists…
homestead: E: The repository ‘Index of /pub/repos/apt/ bionic-pgdg Release’ no longer has a Release file.

I would be very gratefull if someone could help,
thank you.
