When trying to build navcoin-core ./configure (to be exact) I was getting this error:
checking for Berkeley DB C++ headers... no
configure: error: libdb_cxx headers missing, Navcoin Core requires this library for wallet functionality (--disable-wallet to disable wallet functionality)
needed this lib to make it work
sudo apt-get install -y libdb5.3++-dev
So basically on Ubuntu 18.04 this lib was present after running your script libdb5.3++ but also need libdb5.3++-dev
