somewhere along the way, when I started the computer I chose to run a previous version, probably after a failed update. Since then I have added many users. Last week I restarded the computer and chose the current kernel and the users were gone and the more recently added programs were gone. I restarted, chose previous version, chose kernel 48 and everything was fine.
How can I make this previous version the current working version? Do I simply run updates or will that update the version I am not using?
My thought is to delete all the other newer versions, restart, then update.
Many posts suggested using Tweak to remove older kernels. Is that what I should use or does anyone have a better suggestion.
