I installed a debian file (db1'say) using dpkg -i and an executable file (ex1 say) was created.
Later another debian file (db2) was installed, overwriting the executable ex1.
I now wish to overwrite ex1 with the data in db1, so I tried to install db1 again, but nothing seemed to happen.
Did nothing happen because db1 had already been installed ?
Do I need to completely uninstall db1 by using
dpkg --purge db1
before I can install db1 again and overwrite ex1 with data from db1 ?
