yum claims python isn't installed

Question

Trying to install collectd, but for some reason it claims python isn't installed:

yum install collectd

 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
[root@vitlinpup001 templates]# find / -iname "libpython2.4.so.1.0" -type f
/usr/lib64/libpython2.4.so.1.0
[root@vitlinpup001 templates]# file /usr/lib64/libpython2.4.so.1.0
/usr/lib64/libpython2.4.so.1.0: ELF 64-bit LSB shared object, AMD x86-64, version 1 (SYSV), stripped
[root@vitlinpup001 templates]# ls -lah /usr/lib64/libpython2.4.so.1.0

[root@vitlinpup001 templates]# yum info python | grep installed
Repo       : installed

I've tried to run package-cleanup --problems, package-cleanup --dupes and rpm -Va --nofiles --nodigest.

This is a first timer for me regarding missing dependency, so I'm a little lost on how to proceed.

Answer 1

You're misreading the output. It's saying that the 32-bit library for Python is missing, which is correct. Try installing collectd.x86_64 instead.

Answer 2

another work around for this is to add the following line in /etc/yum.conf

exclude=collectd.i386

Answer 3

This seems to be a problem with collectd on EPEL. The x86_64 repository seems to have both 64 bit and 32bit packages. Which is clearly broken.

Adding exclude=collectd.i386 to /etc/yum.conf as mentioned by kisoku is probably the best solution until EPEL is fixed, if you want yum install collectd to "just work"

Answer 4

You can tell Yum to prefer packages that match the machine architecture if more than one is available. Set the following in yum.conf:

multilib_policy=best

This replaces the previous yum-basearchonly plugin as core functionality. It is the default behaviour in Fedora 9 and RHEL 6 onwards.
