Remove unused packages - Fedora

I have installed some rpm package on my fedora 17. Some packages had a lot of dependencies. I have removed some packages but I

forgot remove unused dependencies with yum remove.

How can I do that now?

Many thanks!

It's not easy. How do you differentiate between "a file that was required by something I have

since removed" from "a file that is not required by anything else that I really want"?

You can use the command from the package to list "leaf nodes"

in your package dependency graph. These are packages that can be removed without

affecting anything else:

package-cleanup yum-utils

$ package-cleanup --leaves

This will produce a list of "libraries" on which nothing else depends. In most cases you can

safely remove these packages. If you add to the command line:--all

$ package-cleanup --leaves --all

You'll get packages that aren't considered libraries, also, but this list is going to be so long that

it probably won't be useful.

APT (the Debian equivalent of Yum) has a notion of “automatically installed package”. If a package wasn't explicitly

requested but only pulled in as a dependency, it'll be automatically removed (with a confirmation prompt) if the

packages that depend on it are all removed. Without an indication of this type, it is indeed not easy. Gilles Jun 6

If you install a package with , say , it will pull in a lot of

dependencies:

yum install pdftk

Installed:

pdftk.x86_64 0:1.44-10.fc18

Dependency Installed:

bouncycastle.noarch 0:1.46-6.fc18

itext-core.noarch 0:2.1.7-14.fc18

libgcj.x86_64 0:4.7.2-8.fc18

bouncycastle-mail.noarch 0:1.46-6.fc18

java-1.5.0-gcj.x86_64 0:1.5.0.0-40.fc18

sinjdoc.x86_64 0:0.5-13.fc18

bouncycastle-tsp.noarch 0:1.46-5.fc18

will remove only that package and not all the dependencies.yum remove pdftk

But you can look at all the 'transactions' (install, remove etc.):

$ sudo yum history list pdftk

ID | Command line | Date and time | Action(s) | Altered

-------------------------------------------------------------------------------

88 | install pdftk | 2012-12-14 13:35 | Install | 11

And then you can undo that transaction:

$ sudo yum history undo 88

Undoing transaction 88, from Fri Dec 14 13:35:34 2012

Starting from Fedora 18, you can simply use this command

yum autoremove

or

yum remove --setopt=clean_requirements_on_remove=1

You can also apply autoremove command with specific package

yum autoremove <package>

Which will remove unneeded dependencies from that installed package. autoremove is very

much an aliais of "remove --setopt=clean_requirements_on_remove=1" but for some reasons,

is still undocumented.
