Installation Chain
apt, apt-get, apt-cache talks to the repository servers, download .deb, calculate dependency tree, the hand the final files to dpkg for the actual install. E.g.,
1
sudo apt install curl
- apt finds curl & its deps
- downloads .debs
- dpkg -i each_downloaded.deb
dpkg
dpkg, the debian package manager, works directly with .deb files. It maintains a database of Debian packages.
dpkg -i <FILE>.deb: install.debfiledpkg -r foo: remove (remove the binaries but keeps config files)dpkg -P foo: purge (remove the binaries + configs)dpkg -S <Path>: search forpathof the file.dpkg -S /usr/bin/python3 → python3.8: /usr/bin/python3dpkg -l: Shows version, description of all deb packages
