OTP update issue 2.1.0, ncurses-6, libtinfo.so.6

When trying to update to 2.1.0 i am receiving the following error: ~# su pleroma -s $SHELL -lc "./bin/pleroma_ctl migrate" /opt/pleroma/erts-10.7.2.1/bin/beam.smp: error while loading shared libraries: libtinfo.so.6: cannot open shared object file: No such file or directory

i'm didn't see any other extra steps for OTP release and I also tried to install the missing library with the following results: E: Unable to locate package libtinfo.so.6

I'm running Ubuntu 18.04 (LTS) x64

This is the update steps I used: systemctl stop pleroma systemctl stop nginx su pleroma -s $SHELL -lc "./bin/pleroma_ctl update" su pleroma -s $SHELL -lc "./bin/pleroma_ctl migrate"
