I also notice that running apt update throws the following error:
E: The repository 'http://ppa.launchpad.net/bdbcat/opencpn/ubuntu eoan Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
Please could you let me know how to install plugins in Linux. Without the O-Charts plugin OpenCPN is completely unusable for me. This worked on previous versions.

That is not Ubuntu release info. That's the kernel version your distro is running.
type the following command on a shell terminal instead to get your release: lsb_relase -a

Distributor ID: Ubuntu
Description: Ubuntu 19.10
Release: 19.10
Codename: eoan
I've removed the PPA from /etc/sources.d/ and re-run update.
I then run
apt-cache search opencpn-plugin
opencpn - Concise chartplotter and navigation software
opencpn-plugin-climatology-data - Data for theOpenCPN Navigation software Climatology plugin
opencpn-plugin-launcher - Launcher plugin for OpenCPN
Finds only 2.
There are no OpenCPN releases for eoan. O only target the Long Term Releases such as 18.04 (bionic). Having said that you should be able to use the bionic versions of the plugins. You just have to edit your repository source to use bionic instead of eoan.

Note that this method is not, generally, guaranteed to work. In the case of eoan - bionic it works as no major upgrades for OpenCPN's dependencies was done in eoan. The next version of Ubuntu - 20.04 will be a different beast, with Gtk2 changing to Gtk3, among other things.
