I had a look at the apt log, and I think removing the third-party nodejs package might help. Please run "sudo apt remove nodejs" and then try again.

[Paul Linney (paullinney)]

It was indeed nodejs and after removal the upgrade installed ok.

Thanks so much for looking at the log files and seeing what I missed. I appreciate the time taken to look into this issue.

Many thanks,
Paul
