pkg is the exact name of the package you want to work on.

Example:
To install a new package called nginx, enter:
apt install nginx

For more specific and detailed info.
Use the man command or --help option.

Example:
man apt
apt --help
.

Big Note:
The latest version of Bookworm Pup64 should have a information file under menu -> Help -> How to use the APT Package Manager

Note:

apt upgrade will only update user-installed packages. Updates for preinstalled packages are (intentionally) disabled using apt-mark hold to avoid updates from polluting your save file/folder and/or slowing down the system, and to prevent updates from undoing Puppy-specific customization done to the Debian packages at Puppy build time.

You can use apt-mark unhold to allow updates to a package, but this is risky. Updating your entire Puppy to a new build is a much safer way to update all core system packages.

(Debian 12 is currently frozen and the only changes are important bug fixes. If you don't see any available updates or see updates today but don't see more updates tomorrow, this is probably why. Generally, the Debian stable release receives few updates, just stability and security fixes, and Debian 12 will receive even fewer updates after the release.)

I found 'apt autoremove' does a cleanup & should be run after 'apt remove (pkg name)', to remove remnants.

Example for getting all sub-packages and optional dependencies.

program VLC

You can use apt install --install-recommends vlc to install VLC including all optional sub-packages and optional dependencies.

Thanks to dimkr for this information!

/var/log/apt/history.log is a record of packages you add/remove with apt. It can be handy, I also like to copy/paste the suggested/recommended packages in a text editor and save them in a folder, like /root/AptNotes or something.

Especially with the A/V stuff, sometimes an app is missing a feature or something doesn't work right and I can go back to the suggested packages when I installed it and find what I need to make it work.

apt install --install-recommends vlc | tee vlc.log

will create the file vlc.log that contains the sometimes helpful messages that roll by during the install.

Some may not know, one of the differences between how apt and apt-get operates is that when installing package(s) using apt, e.g. apt install <package(s)>, then after install succeeded, the downloaded .deb files will be removed.
As opposed to when using apt-get, apt-get install <package(s)>, then the .deb files will be kept in /var/cache/apt/archives/ .
edit: and to remove these cached .deb packages: apt clean
edit2: When installing from Synaptic, it works the same as apt-get, i.e. packages are not removed from the cache after installing.

Especially handy for whatever archiving/unzipping program you use so you don't have to lookup and install the package for each format as they fail to work.

Hm. Nice one.

Thanks to everybody for posting this info. I had to laugh; everybody else in the Linux world has been using this stuff for decades.....yet here WE here, just learning all this for the first time!

It's all good stuff, though.
