How to uninstall newly installed dependencies for a RPM package?

  • 772

Is there an easy way to make a list of the dependencies a newly installed RPM package will install with yum?

Example: If you do yum install ruby then it will also install some rubygems.

But when I uninstall the ruby package I also want to get rid of the dependencies it installed.

So my first idea were to make a list of those new packages, and then do an rpm -e on those when I uninstall ruby.

Question

How to make such list in an automated way?

Or is there an easier way then to have to manage text files with rpm package names?

    yum keeps its own history, so you can find out when a package was installed or updated using its history.

    For instance, yum history packages-info ruby will give you all the transactions involving ruby, where the oldest one is usually the one where the package was installed.

    Transaction ID : 102
Begin time     : Thu Apr  3 17:15:17 2014
Package        : ruby-2.0.0.353-16.fc20.x86_64
State          : Install
Size           : 64,734
Build host     : buildvm-17.phx2.fedoraproject.org
Build time     : Thu Nov 28 06:01:20 2013
Packager       : Fedora Project
Vendor         : Fedora Project
License        : (Ruby or BSD) and Public Domain
URL            : http://ruby-lang.org/
Source RPM     : ruby-2.0.0.353-16.fc20.src.rpm
Commit Time    : Mon Nov 25 07:00:00 2013

Reason         : user
Command Line   : install ruby rubygems
From repo      : updates

    This will give you the transaction ID, which you can then look up and find the dependencies which were installed, e.g. with yum history info <ID>.

    Transaction ID : 102
Begin time     : Thu Apr  3 17:15:17 2014
Begin rpmdb    : 2336:55d492c6f5d091f328529861bdf95111264337f6

    Dep-Install rubypick-1.1.1-1.fc20.noarch            @updates/20

    If the package was just installed, and hasn't yet been updated, you can rollback the transaction with, e.g. yum history undo 102. This won't work if any of the packages has been updated since installation, though, as it matches name, version and release.

    And if you really just installed the packages, you can skip everything else and run yum history undo last to rollback the most recent transaction.

  2. You can remove them with yum autoremove.
