When I try to update my laptop running Ubuntu 18.04.1 LTS I use the commands sudo apt update and sudo apt-get update and every time I get this message:
E: The repository 'cdrom://Ubuntu 18.04 LTS _Bionic Beaver_ - Release amd64 (20180426) bionic Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.
W: GPG error: https://dl.bintray.com/resin-io/debian stable Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 379CE192D401AB61
E: The repository 'https://dl.bintray.com/resin-io/debian stable Release' is not signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.
Has the OS updated? What should I do so that it updates?

Just remove your repository above from sources.list,
The repository 'cdrom://Ubuntu 18.04 LTS _Bionic Beaver_ - Release amd64
and try update and upgrade again your system.
Hope this helps.

With CDROM in the /etc/apt/sources.list you will not likely to find updates there. The RESIN repository will only find etcher, you can add the gpg key if you want to get rid of the error message.
To add an internet mirror, you can run this command to add an apt repository
apt-add-repository http://archive.ubuntu.com/ubuntu
You can find official mirrors closer to you here:
