greetings to one and all. a new iso burn w/ centos 6.8 failed to boot on a 686 32 bit mid tower box, but will boot a 32 bit laptop, so i dropped back to 6.7 which did boot. after install with centos 6.7, attempt to upgrade fails with 'repolist 0'. all desire repo files have enable = 1. searched thru past 4 yrs of personal archives, nothing found related to 'repolist 0'. ran web search for 'repolist 0' and 'repolist = 0' with all hits related to repo files having 'enable = 0'. any suggestions/ideas/clues as to solution of problem greatly appreciated. -- peace out.
