Hi all

Newb here with a fresh install of linuxlite 5.0. After installation, I tried to update software but got the following errors. I hope someone is able to help and guide me in the right direction to fix this. Many thanks.

You have something already open - perhaps command line or synaptic?  Close any open windows/apps.
You can close any of these to release the lock or if you cannot locate the app you can try rebooting and rerunning.
