In every ubuntu derivative, if I open a terminal and type an unrecognized command I always get suggestions.
This is so far not what happens with debian 12.5. What package do I need?
And what do debian users use to find new packages from the terminal?
To manage packages on the terminal, I personally like to use aptitude which has a nice visual interface to find, install, and remove packages. It also lets you resolve conflicts interactively. If you do not want a separate tool, you can use
apt-cache search
to search for new packages.As is typical with Linux, there are multiple ways to do it. I found an article that outlines a few alternatives.
