APT is the package manager on Debian based Linux distributions and includes apt-get and dpkg and related utilities.

Usage

Task	Command
Install a package by name	# apt-get install <package>
Remove a package by name	# apt-get remove --purge # apt-get autoremove <package>
Upgrade a package	# apt-get update # apt-get upgrade <package>
Search for a package	# apt-cache search <package> Apt gathers all the commands together, so you can now do: # apt search package
List installed packages	# dpkg -l
Look for a specific package by name	# dpkg -l <package name>
Determine which package provided a file	# dpkg -S <path to file>

Troubleshooting

Couldn't create temporary file /tmp/apt.conf.* for passing config to apt-key

On a clean install of Raspbian Buster, I got:

# apt-get update
Get:1 https://repos.influxdata.com/debian buster InRelease [4,731 B]

It turns out /tmp wasn't configured with the right permissions and only root could write to it. To fix this, run:

# chmod 1777 /tmp
