Description Horst H. von Brand 2010-05-09 12:07:23 EDT

Description of problem:
I've installed texlive-2009, which still uses libpoppler.so.5. This causes a lot of packages that can't be updated, and yum chokes (see part of the error message below).

yum-3.2.27-11.fc14.noarch

How reproducible:
Almost always.

Steps to Reproduce:
1. yum update --skip-broken
2.
3.
  
Actual results:
Lots of messages in the line of

Expected results:
Detect non-updatables, update the rest...

Additional info:
texlive-2010-5.20100430.fc13.x86_64 (and a selection of others from there) installed.

Installing a lot of non-conflicted packages by hand ("yum upgrade --skip-broken list-of-packages") usually then makes the next try at "yum upgrade --skip-broken" go through.

patch to fix skip-broken loop detection issue

Comment 4 Tim Lauridsen 2010-05-17 03:51:43 EDT

Look like the skip-broken loop detection bails out to early.

Could you please try to add the attached patch to 

/usr/lib64/python2.6/site-packages/yum/__init__.py

to see if it solves the issue.

Comment 5 Horst H. von Brand 2010-05-17 08:15:48 EDT

Seems to fix it (no new updates, but yesterday after updating everything that could be it complained also). Will report back after today's round of updates.

BTW, here the file is /usr/lib/python2.6/site-packages/yum/__init__.py (plain "lib", not "lib64").

Luckily, patch(1) did "get" your git(1) patch, if it hadn't I'd been at a loss.

Now go on and file a bug against bugzilla, as it isn't exactly easy to get the raw patch for testing...

Comment 6 Horst H. von Brand 2010-05-17 14:56:38 EDT

Yep, fixed. Another machine showed the same problem with today's round of updates, after the patch the update goes through.

Comment 7 Horst H. von Brand 2010-05-18 17:43:33 EDT

Survived today's round of updates too.

Comment 8 Tim Lauridsen 2010-05-19 01:08:18 EDT

Thanks for testing :)
The real test is in cases where there is a lot of updates and multiple packages with despolve issue, but that don't happen very often.

The patch has been pushed upstream, I will close for now, please reopen if you hit any issues again
