Python problems with FC5

saywot · 09-05-2006, 10:56 AM

I have been getting error messages when I use the command
yum-y update.

Quote:

[root@usaidwot saywot]# yum -y update
Could not find platform independent libraries <prefix>
Could not find platform dependent libraries <exec_prefix>
Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
'import site' failed; use -v for traceback
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:

No module named yum

Please install a package which provides this module, or
verify that the module is installed correctly.

It's possible that the above module doesn't match the
current version of Python, which is:
2.4.1 (#2, Nov 11 2005, 12:26:27)
[GCC 4.0.1 (4.0.1-5mdk for Mandriva Linux release 2006.0)]

which is odd as I seem to have installed a Mandriva Linux component and this is FC5.

Also when I download and have run rpm -ivh Python-2.4.x.x.x.FC5.i386.rpm
I get you have already installed this

and the same applies to installing YUM

How can I get rid of the Mandriva components and replace with the appropriate Fedora Core equivalents

Here's the message I get when I try and install a later (FC5) version of Python

Quote:

[root@usaidwot saywot]# rpm -ivh python-2.4.3-8.FC5.i386.rpm
Preparing... ########################################### [100%]
package python-2.4.3-8.FC5 is already installed

saywot · 09-05-2006, 09:58 PM

and, of course, the same applies to YUM

Quote:

[root@usaidwot saywot]# rpm -ivh yum-2.6.1-0.fc5.noarch.rpm
Preparing... ########################################### [100%]
package yum-2.6.1-0.fc5 is already installed

So while I can blame myself for doing things to my computer waaaay past my bedtime I would have thought a simple

Quote:

rpm -e [package-name]

should remove all of python - but NO !

# rpm -e python2.4.1

# rpm -e Python2.4.1

But when I do (as the super user)
rpm -ivh python-2.4.3-8.FC5.i386.rpm

Quote:

# rpm -ivh python-2.4.3-8.FC5.i386.rpm

So V 2.4.1 is not installed
but V 2.4.3 is

YUM needs python to work and the command I use to update all the packages is
yum -y update
so when I use this (again as su) I get

Could not find platform independent libraries <prefix>

So that which doesn't exist does indeed but that which shouldn't does
The package I'm trying to remove isn't there
the package I'm trying to install is already installed

I'm starting to think that my only solution is to do a complete re-install of Core 5.

I have looked through all of /etc and found nothing called (or resembling) python 2.4.1 there
have looked through /usr with the same result

Where else should I be looking as (apart from this) I have the machine running everything I wanted above my expectations ?

Have you tried yum clean all
It's a long shot, but may help, before you try a reinstall.

saywot · 09-07-2006, 09:14 AM

Well if

yum -y update

returns an error message of "Yum is not installed"

Quote:

yum clean all

will probably return the same message won't it ?

something like

Quote:

# yum clean all
Could not find platform independent libraries <prefix>
Could not find platform dependent libraries <exec_prefix>
Consider setting $PYTHONHOME to <prefix>[:<exec_prefix>]
'import site' failed; use -v for traceback

woops, sorry didn't mean to increase your frustration, guess i should have read a bit more carefully.

saywot · 09-11-2006, 01:51 AM

Latest --

#updatedb --(wait a few minutes)
#locate python

this gives me the location of the file I don't want
remove the file
replace with Python 2.4.3 FC5
installs like a charm !! - (briefly happy and hopeful)

This all started because I was unable to update anything because of the incorrect version of Python now this has been solved I expected the problem to have cleared up

But

So now rpm has gone and I'm no better off (except I do have python 2.4.3 FC5 installed)

You hosed python, yum and rpm by installing Mandriva packages on Fedora Core. Whilst Mandriva and Fedora Core share the same basic package management system, their packages are not compatible. Since rpm is hosed and there is not way to reinstall yum, python and rpm a complete OS reinstall maybe necessary.

Which leads me ...
with the greatest reluctance to accept this as sage advice

but
Since I have re-installed the correct python package, the correct yum package what's the impediment to fixing rpm ?

reddazz · 09-11-2006, 04:22 PM

Since rpm seems to be somehow working, try doing

Code:

# rpm -Uvh --nodeps --force rpm-4.4.2-15.2.i386.rpm

Make sure you use the latest rpm available from the updates section in the Fedora Core mirrors. Also make sure your reinstall the rpm-python package.

This looked good so I tried it

OK so rpm forced itself

Now to the latest python from the fedora core repository
so python forced itself

But to no avail the report is still

"no module named rpm"

So I'm still at a loss

reddazz · 09-12-2006, 03:12 AM

Did you read the last bit of the post that talks about rpm-python?

# rpm -ivh python-2.3.4-13.1.i386.rpm
error: Failed dependencies:
libdb-4.2.so is needed by python-2.3.4-13.1.i386
libreadline.so.4 is needed by python-2.3.4-13.1.i386

So should I install the dependencies OR do the "nodeps" thing
