This write up will be useful to both new and veteran Debian users Linux OS. I am currently an undergraduate student in my 1st year.
I am an internee author with Linuxhint and loved learning the art of technical content writing from senior authors. I am looking forward to opting my career as a full time Linux writer after I graduate. The apt-get command is a common and useful Linux command. If you are new to Linux, then you must know the usage of this command. Thanks to this your system can see if an installed package has new version available. In fact, you can see the packages that can be upgraded using:.
It is important to run the apt update command before so that your system is aware about the availability of the new version of packages. With that information, the apt upgrade command fetches the new version of the packages from the Debian repositories and installs them. Why is the -y option used here? Because the apt upgrade needs your conformation before downloading and updating the system.
You can save some time by supplying it with yes thanks to the -y. This way, you don't need a manual intervention while updating Debian. Everything is done in a single command even if it is a combination of multiple commands. Please enter at least 3 characters 0 results found.
They look and act the same, but one can accidentally nuke your OS, so be careful. If your install gets interrupted, you want to make use of: sudo apt -f install. In order to remove this, run the following:. These should not be manually removed! You can also run: sudo apt autoclean to only remove deb files for outdated packages only.
These can all take multiple packages as necessary. This just removes the selected package. The difference is that remove only removes the packaged parts and purge removes the package and all relevant configurations and cache.
This is one of the few commands which cannot be used with apt-get. Something like aptitude can be installed and used where apt may not be available much older distributions. In order to edit the sources. Install automatically attempts to resolve dependency problems with the listed packages and will print a summary and ask for confirmation if anything other than its arguments are changed. Dist-upgrade is a complete upgrader designed to simplify upgrading between releases of Debian. It uses a sophisticated algorithm to determine the best set of packages to install, upgrade and remove to get as much of the system to the newest release.
In some situations it may be desired to use dist-upgrade rather than spend the time manually resolving dependencies in dselect. Once dist-upgrade has completed then dselect can be used to install any packages that may have been left out. It is important to closely look at what dist-upgrade is going to do, its decisions may sometimes be quite surprising.
