This site is for the co-ordination of the Ubuntu project(s), and not support.

For Ubuntu Support options, there are many listed at https://community.ubuntu.com/t/finding-help/712

Just run ‘sudo dpkg --configure -a’ to correct the problem. That’s what you do, when dpkg gets interrupted.

And, if you have further problems, check with Ubuntu forums. https://ubuntuforums.org
