Hi Michael; Aside, the python-list@#python.org was just as stumped as
we were, but please read on for a blow by blow report.
Thinking I had a mobo/memory problem, I've now thrown $410 at this
problem, for a new mobo, 2x the memory, and 2x faster cpu, basicly so
I can make mysteaks 2x as fast :)
My mistake/error isn't exactly the same, but its very very close, here
is a fresh snip:
-------------
[root at coyote root]# yum update
Traceback (most recent call last):
File "/usr/bin/yum", line 22, in ?
import yummain
File "/usr/share/yum/yummain.py", line 31, in ?
import yumcomps
File "/usr/share/yum/yumcomps.py", line 4, in ?
import comps
File "/usr/share/yum/comps.py", line 5, in ?
import libxml2
File "/usr/lib/python2.2/site-packages/libxml2.py", line 1, in ?
ImportError: No module named libxml2mod
----------------
Humm, now thats a fresh error, but why is it now reverting to looking
in the python 2.2 tree? Without disturbing the 2.2 tree, the 2.3
tree is installed alongside it, and the appropriate links corrected
(I thought).
ATM, an ls -l on that dir (once I fix the ^#$*% links in /usr/bin
again) returns:
[root at coyote bin]# ls -l /usr/lib/python2.3/site-packages/
total 1396
-rw-r--r-- 1 root root 15097 Jul 1 05:19 drv_libxml2.py
-rw-r--r-- 1 root root 336540 Jul 1 05:19 libxml2mod.a
-rwxr-xr-x 1 root root 900 Jul 1 05:19 libxml2mod.la
-rwxr-xr-x 1 root root 254768 Jul 1 05:19 libxml2mod.so
-rw-r--r-- 1 root root 291327 Jul 1 05:19 libxml2.py
-rw-r--r-- 1 root root 493151 Jul 15 11:23 libxml2.pyc
-rw-r--r-- 1 root root 119 May 27 05:29 README
And, with the links fixed again (so /usr/bin/python is a link from
python2.3 in that dir), running yum returns this:
--------------------
[root at coyote bin]# yum update
Traceback (most recent call last):
File "/usr/bin/yum", line 22, in ?
import yummain
File "/usr/share/yum/yummain.py", line 22, in ?
import clientStuff
File "/usr/share/yum/clientStuff.py", line 18, in ?
import rpm
ImportError: No module named rpm
----------------------
Ok, I'll bite, where is the rpm stuff for python? I've reinstalled
this ,rpm-python-4.2.1-0.30 but that had no effect on this. I'm
about to rip out all python and reinstall, but my ripout will be with
mc (probably, I want it gone before I re-install)
Update: I blew away the python2.3 install with an rpm -e, and rebuilt
the links in /usr/bin yet again, and I am now back a wee bit closer
to the original error:
[root at coyote bin]# yum update
Traceback (most recent call last):
File "/usr/bin/yum", line 22, in ?
import yummain
File "/usr/share/yum/yummain.py", line 31, in ?

import comps
File "/usr/share/yum/comps.py", line 5, in ?
import libxml2
File "/usr/lib/python2.2/site-packages/libxml2.py", line 1, in ?
ImportError: No module named libxml2mod
Humm, cd to yum/updates-released/packages and
#> "rpm -Uvh --force libxml2*" reinstalled those 3 packages but as a
small downgrade. Now I'm back to the original error that started a
month ago, and $410 for a new system board memory and cpu trying to
fix it since, there were memory errors caused by a dying nvidia
display board.
----------------
[root at coyote packages]# yum update
Traceback (most recent call last):

import libxml2mod
ImportError: /usr/lib/python2.2/site-packages/libxml2mod.so: undefined
symbol: xmlByteConsumed
------------------
Now, I have NDI (no damned idea) exactly when yum itself installed
those 3 or 4 packages, all I know is that at about that time frame,
maybe a little over a month ago now, yum stopped working here with
the above error. I'm tempted to go back to the FC1 install cd's and
re-install that version, which did indeed work just fine. In fact
thats a heck of a good idea, brb.
Guess what folks, that indeed fixed it! I had to rpm -e a bunch of
devel stuff before I could revert libxml2-devel, but they aren't
something I'll miss. Please, somebody go back to the repo's and see
WTF happened. That was fedoras own FC1 "updates-released" repo that
poisoned my system.
Now, how do I get a yum update to leave this stuff alone instead of
self-destructing. Can I add more than one line of excludes to
yum.conf? Sure seems like a great idea from this viewpoint!

Now, this isn't quite the same error, but right now I'd bet a beer
that a reversion of the python and rpm-python plus libxml2 stuff to
the distribution FC1 CD's versions will also fix this gentlemans
problems. _IF_ he's still on FC1 that is. Since its python2.2, I'd
have to assume he is since FC3t1 at least comes with python2.3.4
stuffs and IIRC FC2 has python2.3.2.

Hung, maybe this will fix it for you too?
