package scite 3.3.5-1 failed to install/upgrade: ErrorMessage: EOF on stdin at conffile prompt - requested root password without any means to enter it

[Antony den Dulk]

Used Control-Alt-F1 to run the do-release-upgrade and left overnight. In the morning it was stuck on a screen asking if I wanted to keep the old file or replace with the package managers new version. After the selection it requested the root password or Control-D to continue. Tried to enter the password and it straight away bought up the message again.
