Question apt error

i am using Linux mint and sometimes i got errors when i am updating the system using apt .
my question is about the letters in the error messages. the letter W or the letter E .. to make my self clear i am not asking about the errors them self, i am only interested in the letters before them

W: GPG error: stable Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 9AA38DCD55BE302B NO_PUBKEY 4D270D06F42584E6
E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.

what am i supposed to know from W or E
thanks for your time guys ...

"E:" indicates an error message. Not sure about "W:" though.

ETA: Okay, I think "W:" stands for "warning". So, "E" is Error, and "W" is warning. I got that from the following URL, which indicates that "W" is a warning. If the warning is ignored and a user's action is leading to something more serious, then it will fully spell out "WARNING". See for an example, wherein it's described as "If you ignore that warning and try to install a package later, apt will warn again: ..."
