= APT commands on Fedora
|
|
|
|
APT is the package manager/dependency solver for the Debian ecosystem, i.e. it manages `.deb` packages installed by the dpkg program. Fedora software uses `.rpm` packages, and thus uses DNF, the package manager/dependency solver for the RPM program. This document gives a brief overview of the most common APT commands one might find in tutorials and their DNF equivalents.

|
.Apt vs DNF commands
|
|
|===
|
|
| APT command | DNF command | notes
|
|
|
|
| `apt update`
|
|
|
|
`apt-get update`
|
|
|
|
| `dnf check-update`
|
|
| This command is rarely needed, as dnf updates its package cache automatically when it is stale. A cache update can be forced by appending `--refresh` to other commands, e.g. `dnf upgrade --refresh`
|
|
|
|
| `apt upgrade`
|
|
|
|
`apt-get upgrade`
|
|
|
|
| `dnf upgrade`
|
|
|
|
|
|
|
| `apt full-upgrade`
|
|
|
|
`apt-get dist-upgrade`
|
|
|
|
| `dnf distro-sync` or
|
|
|
|
`dnf system-upgrade` (see note)
|
|
|
|
| While `distro-sync` is the most direct functional equivalent, `dnf system-upgrade` should be used to upgrade from one release to another, e.g. from Fedora 31 to 32. This is a multi-step process as described xref:dnf-system-upgrade.adoc[here].
|
|
|
|
| `apt remove`
|
|
|
|
`apt-get remove`
|
|
|
|
| `dnf remove`
|
|
|
|
|
|
|
| `apt purge`
|
|
|
|
`apt-get purge`
|
|
|
|
| ---
|
|
|
|
|
|
|
| `apt autoremove`
|
|
|
|
`apt-get autoremove`
|
|
|
|
| `dnf autoremove`
|
|
|
|
|
|
|
| `apt search`
|
|
|
|
`apt-cache search`
|
|
|
|
| `dnf search`
|
|
|
|
|
|
|
|===
|
|
|
|
With the exception of of the dist-upgrade working different and dnf updating the cache automatically, the commands are very similar. More info on DNF can be found xref:dnf.adoc[here].

== Why is APT in the Fedora repositories?
|
|
|
|
WARNING: APT *can not* be used to install packages on Fedora, you *have to use DNF* instead.
|
|
|
|
The `apt` command on Fedora used to - until https://fedoraproject.org/wiki/Changes/Move_apt_package_from_RPM_to_DPKG_backend[Fedora 32] - actually be `apt-rpm`, which basically mapped normal apt commands so that they worked with Fedora's RPM package management system.
|
|
|
|
However, `apt-rpm` is unmaintained, broken & insecure, and so was dropped in favour of shipping the actual Debian `apt` software. Since `apt` exclusively deals with `.deb` packages, the `apt` command can no longer be used to manage Fedora packages. It's purpose is now purely as a tool for people trying to build packages for Debian-based distributions on a Fedora system.
