Not much to introduce, I'm new, Hi.
I just wanted to say, you folks are all lovely. The sense of community you get in the posts and comments, the genuine care and respect for other people in the conversation.
I'm happy to be here, hopefully the vibe weathers the user storm.

Moving from Ubuntu to a debian based distro makes sense - a lot of stuff is familliar. Base debian is fine, but MX is a little more friendly. They have a KDE image here: https://mxlinux.org/download-links/
