![]() ![]() Performs the following command with super-user (root) capabilities. Sudo apt-get update essentially has three parts: sudo You need sudo both times, but since sudo by default doesn't prompt you within 5 or so minutes since the last sudo operation, you will be prompted for your password only once (or not at all).Ī Google search can give you the definition for almost any terminal command, as can -help in the terminal. Or to get newest versions possible as per version requirements of dependencies: sudo apt-get update & sudo apt-get dist-upgrade You can combine commands with & as follows: sudo apt-get update & sudo apt-get install foo bar baz foo-dev foo-dbg ![]() See also apt_preferences(5) for a mechanism for over-riding the general settings for individual packages. The /etc/apt/sources.list(5) file contains a list of locations from In addition to performing the function of upgrade, this option also intelligently handles changing dependencies with new versions of packages apt-get has a "smart" conflict resolution system, and it will attempt to upgrade the most important packages at the expense of less important ones, if necessary. See here: What is "dist-upgrade" and why does it upgrade more than "upgrade"? An update must be performed first so that apt-get knows that new versions of packages are available.Īpt-get dist-upgrade ( on apt equivalent to full-upgrade) will do the same job which is done by apt-get upgrade, plus it will also intelligently handle the dependencies, so it might remove obsolete packages or add new ones. New versions of currently installed packages that cannot be upgraded without changing the install status of another package will be left at their current version. Packages currently installed with new versions available are retrieved and upgraded under no circumstances are currently installed packages removed, nor are packages that are not already installed retrieved and installed. Used to install the newest versions of all packages currently installed on the system from the sources enumerated in /etc/apt/sources.list(5). An update should always be performed before an upgrade or dist-upgrade.Īpt-get upgrade will fetch new versions of packages existing on the machine if APT knows about these new versions by way of apt-get update. The indexes of available packages are fetched from the location(s) specified in /etc/apt/sources.list(5). Used to re-synchronize the package index files from their sources. It will do this for all repositories and PPAs. Instead, it updates the package lists for upgrades for packages that need upgrading, as well as new packages that have just come to the repositories.Īpt-get update downloads the package lists from the repositories and "updates" them to get information on the newest versions of packages and their dependencies. To read more about dpkg and apt refer to Debian wiki.In a nutshell, apt-get update doesn't actually install new versions of software. dpkg can however be used to install and list locally installed packages. APT instead utilizes dpkg under the hood to install packages. Conclusionĭpkg and APT are not made to do the same things. That said, dpkg does have exclusive uses such as configuring/ unpacking/ repacking and comparing packages as discussed above. To list packages, we can use apt list instead of dpkg -l. ![]() ![]() To install a local package we can use apt install.Most of what dpkg does can be done directly through apt as shown below. deb packages that aren’t available on remote repositories such as Discord and Steam. Using dpkg over APT would mean, manually downloading the package, manually figuring out and downloading all dependencies, manually downloading any upgrades, etc. NO (users need to manually download a package if they wish to use dpkg)ĭpkg is a low-level application usually not supposed to be used by the end-user. Can download packages from remote repositories ![]()
