Q:

I am trying to install sbt on Ubuntu 16.04.  I have mistakenly stopped the process when running the following command,
sudo apt-get install sbt

Now when I try to install again, I am getting the below error,

A:

it's so long time since you asked.  Because of no answer here, I show you my solution that works well for me. 
The root cause of your problem may be from previous java install (it's not from any repositories, but from manually download package). 
Thus, you must manually remove post-install scripts, use below commands:
sudo rm /var/lib/dpkg/info/oracle-java8-installer.postinst -f
sudo dpkg --configure oracle-java8-installer

Hope them help you. 

A:

For Ubuntu 19.04 and Oracle JDK 11:
sudo rm /var/lib/dpkg/info/oracle-java11-installer-local.postinst -f
sudo dpkg --configure oracle-java11-installer-local

A:

!!  NOTE !! 
This solution may not work if Oracle stops serving files from their FTP service. 
They do that for older Java releases. 

When using ppa:webupd8team/java there can be deprecated/archived Oracle links hardcoded in PPA. 
Oracle is moving their older versions to archive and PPA has internal links to "active" (at the time of PPA creation) Oracle download versions. 
The maintainer of ppa:webupd8team/java is only one man - Andrew (see here)

Java versions change "often" so update 8u151 and 8u162 to reflect your environment. ( this versions worked on Ubuntu 16.04.3 LTS - 2018-01-18)

Try again
apt install oracle-java8-installer
apt install oracle-java8-set-default
