Plugin not working

[madmaxmiller]

Thanks for the responses but it is the case that I not seeing the plugins in carla and getting a system error message.. So I am coming round to updating my ubuntu. What's your opinion MMM, with this type of error will I get away with upgrading from 18.04 or do I need a fresh install of 20.04?

If you are considering a fresh install anyway - do it! Upgrades over multiple versions (LTS or not) is not a good idea. In the best case you end up with a lot of clutter.
If you have recycable config files in /etc save them first (I have a few NFS mounts in /etc/fstab for instance), it just saves time later.
