Mint 19.3 vs 20 - different behaviour?

When you run command in a terminal if the program isn't installed you get this message:Code:jonk@jonk-Len-usff:~$ abcde

Command 'abcde' not found, but can be installed with:

sudo apt install abcde

jonk@jonk-Len-usff:~$But with Mint 20 I don't, I get this:Code:jonk@dave:~$ abcde
bash: abcde: command not found
jonk@dave:~$Any suggestions folks?
Just to be clear $PATH is the same on both machines:Code:$ echo $PATH
/home/jonk/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/gamesAnd the Mint versions are both 64bit:Code:jonk@jonk-Len-usff:~$ hostnamectl
