[one-liner]: Using Yum to Download RPMs under Fedora, CentOS, and RHEL

slmingol posted this in tips & tricks on March 30th, 2010, @ 10:37 am

Background

From time to time I’ve run into an RPM that won’t install via yum. These usually pop up because I’ve mixed packages in from a 3rd party repository, and the 3rd party package has some overlapping files with an already installed RPM.

Problem

Here’s an example that happened to me recently on a Fedora 10 system where I was trying to install some pulseaudio related packages.

% yum install xmms-pulse xine-lib-pulseaudio
Package xmms-pulse-0.9.4-6.fc10.i386 already installed and latest version
Resolving Dependencies
--> Running transaction check
---> Package xine-lib-pulseaudio.i386 0:1.1.16.3-2.fc10 set to be updated
--> Processing Dependency: xine-lib = 1.1.16.3-2.fc10 for package: xine-lib-pulseaudio-1.1.16.3-2.fc10.i386
--> Finished Dependency Resolution
xine-lib-pulseaudio-1.1.16.3-2.fc10.i386 from updates has depsolving problems
  --> Missing Dependency: xine-lib = 1.1.16.3-2.fc10 is needed by package xine-lib-pulseaudio-1.1.16.3-2.fc10.i386 (updates)
Error: Missing Dependency: xine-lib = 1.1.16.3-2.fc10 is needed by package xine-lib-pulseaudio-1.1.16.3-2.fc10.i386 (updates)
 You could try using --skip-broken to work around the problem
 You could try running: package-cleanup --problems
                        package-cleanup --dupes
                        rpm -Va --nofiles --nodigest

Solution

If you’re confident that this is a “false positive” type of error you can force your way around it like so. First download the RPM using the never mentioned command yumdownloader.

NOTE: yumdownloader is part of the yum-utils package.

1	% yumdownloader xine-lib-pulseaudio

Next try to install/upgrade the package.

% rpm -Uvh --nodeps xine-lib-pulseaudio-1.1.16.3-2.fc10.i386.rpm 
Preparing...                ########################################### [100%]
	file /usr/lib/xine/plugins/1.26/xineplug_ao_out_pulseaudio.so from install of xine-lib-pulseaudio-1.1.16.3-2.fc10.i386 conflicts with file from package xine-lib-1.1.16.3-18.fc10.i386

This is what I would consider a bogus error. For whatever reason, both RPMs share the same file, so let’s just install it already by doing a forced installation of the RPM.

 % rpm -Uvh --force --nodeps xine-lib-pulseaudio-1.1.16.3-2.fc10.i386.rpm

   1:xine-lib-pulseaudio    ########################################### [100%]

Fixing Ruby Support in Vim on Fedora 10, 11, and CentOS 5 & Installing the Vim Textile plugin

slmingol posted this in tips & tricks on September 28th, 2009, @ 11:00 am

Background

A while back I was trying to get the vim textile plugin installed and ran into a problem. Apparently the vim that’s included with Fedora 10, 11, and CentOS 5 doesn’t include ruby support. This bug report explains what’s wrong with vim and how it’s missing ruby support. The problem is visible with this command:

% vim --version | grep ruby
+printer +profile +python +quickfix +reltime +rightleft -ruby +scrollbind 
...
...

The –ruby tells us that ruby support isn’t enabled. The only solution I’ve seen thus far is to rebuild vim. Not really a huge deal but it’s work non the less 8-).

Rebuilding vim with ruby support

Here’s how I fixed it.

download vim Source RPM (SRPM)

1	% wget http://mirrors.xmission.com/fedora/updates/10/SRPMS/vim-7.2.148-1.fc10.src.rpm

confirm that ruby is installed

% yum list installed ruby*|column -t|grep ruby
ruby.i386        1.8.6.287-2.fc10  installed
ruby-devel.i386  1.8.6.287-2.fc10  installed
ruby-irb.i386    1.8.6.287-2.fc10  installed
ruby-libs.i386   1.8.6.287-2.fc10  installed
ruby-rdoc.i386   1.8.6.287-2.fc10  installed

make sure you have your own rpmbuild directory

% mkdir -p ~/rpmbuild/{BUILD,RPMS,SOURCES,SPECS,SRPMS}
 
# caution with this second command if you already have your own .rpmmacros, this will overwrite!
% echo '%_topdir %(echo $HOME)/rpmbuild' > ~/.rpmmacros

rebuild vim / re-install vim

1 2	rpmbuild --rebuild vim-7.2.148-1.fc10.src.rpm rpm --force -Uvh /root/rpmbuild/RPMS/i386/vim-{c,e,m,X}*

check that vim now has ruby support

% vim --version | grep ruby
+printer +profile +python +quickfix +reltime +rightleft +ruby +scrollbind 
...
...

Ahh. a +ruby means it worked.

Textile Plugin for vim

Now onto installing the vim textile plugin.

First things first, we need to install rubygems

1	% yum install rubygems

Next we need to install the RedCloth gem, it’s required by the textile plugin

% gem install RedCloth
Building native extensions.  This could take a while...
Successfully installed RedCloth-4.2.2
1 gem installed
Installing ri documentation for RedCloth-4.2.2...
Installing RDoc documentation for RedCloth-4.2.2...

Finally, install the textile plugin

Downloading the textile plugin from here,

Setting up XMMS and MP3 support on Fedora 10

slmingol posted this in tips & tricks on April 24th, 2009, @ 9:22 pm

Quick list of the steps I needed to go through in order to get XMMS with MP3 support working on Fedora 10.

# add rpmfusion free
% rpm -ivh http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm
# add rpmfusion nonfree
% rpm -ivh http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm
 
% yum install gstreamer-plugins-bad gsteamer-plugins-ugly xine-lib-extras-nonfree
% yum install xmms xmms-mp3

Couple of notes. I had previously installed atrpms, and xmms & xmms-libs from this repo which didn’t seem to be compatible from the fusion repos. So I disabled the atrpms repo in the /etc/yum.repo.d atrpms files and then ran this command.

1	% yum removed xmms xmms-libs

Thanks to Jack over on the Ghacks.net website for showing me the way on this one quickly. Saved me a ton of time in chasing this one down.

Step 1a: the manual way

NOTE: Lifted from Lic Fessden’s blog here

yum install rpm-build
 
mkdir -p ~/rpm
mkdir -p ~/rpm/BUILD
mkdir -p ~/rpm/RPMS
mkdir -p ~/rpm/SOURCES
mkdir -p ~/rpm/SPECS
mkdir -p ~/rpm/SRPMS

And create the file ~/.rpmmacros with the following in it:
