In what directory did you put the latest sqlite3 executable? Does that directory appear when, in bash, you enter:<code> echo $PATH </code> Here are commands entered (to bash) in a Ubuntu 20 session just now:<code> sudo apt install gcc sudo apt install automake sudo apt install make cd sqlite-autoconf-3340000/ ./configure make sudo mv sqlite3 /usr/bin/ which sqlite3 sqlite3 </code>, which (after omitting much install and build verbosity) yields:<code> SQLite version 3.34.0 2020-12-01 16:14:00 Enter ".help" for usage hints. Connected to a transient in-memory database. Use ".open FILENAME" to reopen on a persistent database. sqlite> </code> I had to build because the 32-bit executable for Linux cannot be run on my 64-bit system, at least not conveniently.
