dist upgrade trouble shooting

Hi.
Thought I would upgrade Kali on my laptop, but the process stopped with a flashing cursor top left. Waited but no good. Rebooted and get command prompt with message about trouble shooting minimal install. Tried continuing upgrade but whatever I try I get error message about unmet dependencies. Have tried loads of stuff from Google, --fix-missing fix broken etc. etc. but still get the same message.
Kali was setup just as I like it, so can I do a sort of repair install keeping all my apps and settings or is a clean install needed?
Thanks ......
