I got the following error on every update.

Pls fix it..

W: A error occurred during the signature verification. The repository is not updated and the previous index files will be used.

That's because the subkey for deb.torproject.org expired, and you don't have the deb.torproject.org-keyring package installed.

Probably the simplest fix is to follow the instructions at https://www.torproject.org/docs/debian.html.en#ubuntu again, i.e., re-fetch and re-add the key. Then apt-get install the keyring this time too.
