Hello, After attempting a migration from CentOS 5.5 to Scientific Linux 5.5, the result is a system in an inconsistent state. The basic stanza used for the migration was from SCIENTIFIC-LINUX-USERS@xxxxxxxxxxxxxxxxx and is below the yum/grep output. Trying to learn more about yum and its use, I ran the commands below the sig. 1) What am I missing about the possible/perceived discrepancies between the outputs of yum repolist and grep? 2) For a given installed package, is it possible to get yum to identify which repository was used for the installation? THANKS for your thoughts. kind regards/ldv Larry Vaden, CoFounder Internet Texoma, Inc. Serving Rural Texomaland Since 1995 We Care About Your Connection!
