DB Browser for SQLite is the new name for SQLite Browser.
Database filtering is not working
In SQLite Browser that comes with Linux Mint (Ubuntu) version 18.1 the Filter function of the database does not work.
Solution: I installed the most recent version of DB Browser and this solved the problem.
To add the update to the Linux repository, run the following code in a terminal:
sudo add-apt-repository ppa:linuxgndu/sqlitebrowser
sudo apt-get update
After this, go to Mint Update and click the Install Updates button.
