Description James Antill 2008-10-27 16:05:24 EDT
Description of problem:
 An optimization that went into ~3.2.19 was that you could "yum remove X" without updating all of the repositories metadata. However a bug has just been found when releasing 3.2.20 upstream that this means if you have:

yum shell <<EOL
remove X
install X
run
EOL

...where previous yum versuions would work fine, yum-3.2.19 will now fail on the "install" operation because the repository data isn't setup. The fix is below, and just 2 lines.

Version-Release number of selected component (if applicable):
yum-3.2.19-10

How reproducible:
always
