CentOS 5 yum error: Error: None

On some new installs of CentOS we have been getting the following error while using yum:

[root@s yum]# yum upgrade
Error: None

To fix this phython sqlite and yum must be re-installed.

First remove phython sqlite and yum, then download and re-install them using the following:

rpm -ivh yum-metadata-parser-1.1.2-2.el5.x86_64.rpm
rpm -ivh python-sqlite-1.1.7-1.2.1.x86_64.rpm
rpm -ivh yum-3.2.8-9.el5.centos.1.noarch.rpm
rpm -ivh yum-updatesd-0.9-2.el5.noarch.rpm

Then execute:

yum clean all
yum upgrade

This should fix the issue.

If you are still having issues try the following:

rm /var/lib/rpm/__db*
rpm –rebuilddb
yum clean all
yum upgrade

Error: Missing Dependency: perl(URI) >= 1.17 is needed by package subversion

Steps to resolve this:

1. Download the perl(URI) with version greater than 1.17 using the following command.

wget http://fr.rpmfind.net/linux/fedora/core/3/x86_64/os/Fedora/RPMS/perl-URI-1.30-4.noarch.rpm

2. Install the specified package using the follwing command.

rpm -i perl-URI-1.30-4.noarch.rpm

3. Install subversion using “yum”.

yum install subversion
You should now have successfully installed Subversion:

[root@sXXX ~]# svn help
usage: svn [options] [args]
Subversion command-line client, version 1.4.2.
Type ‘svn help ‘ for help on a specific subcommand.
Type ‘svn –version’ to see the program version and RA modules
or ‘svn –version –quiet’ to see just the version number.

Most subcommands take file and/or directory arguments, recursing
on the directories. If no arguments are supplied to such a
command, it recurses on the current directory (inclusive) by default.

Available subcommands:
add
blame (praise, annotate, ann)
cat
checkout (co)
cleanup
commit (ci)
copy (cp)
delete (del, remove, rm)
diff (di)
export
help (?, h)
import
info
list (ls)
lock
log
merge
mkdir
move (mv, rename, ren)
propdel (pdel, pd)
propedit (pedit, pe)
propget (pget, pg)
proplist (plist, pl)
propset (pset, ps)
resolved
revert
status (stat, st)
switch (sw)
unlock
update (up)

Subversion is a tool for version control.
