Hey all, Trying to upgrade MySQL from 3.23 to 4.0.16 on a new fedora core3 system. I keep getting the following when I run the servers-standard rpm... Preparing... ###########################################[100%] 1:MySQL-server-standard ###########################################[100%] 050901 17:33:34 [ERROR] Can't create interrupt-thread (error 13, errno:13) Installation of system tables failed! Examine the logs in /var/lib/mysql for more information. You can also try to start the mysqld daemon with: /usr/sbin/mysqld --skip-grant & You can use the command line tool /usr/bin/mysql to connect to the mysql database and look at the grant tables: shell> /usr/bin/mysql -u root mysql mysql> show tables Try 'mysqld --help' if you have problems with paths. Using --log gives you a log in /var/lib/mysql that may be helpful. The latest information about MySQL is available on the web at http://www.mysql.com Please consult the MySQL manual section: 'Problems running mysql_install_db', and the manual section that describes problems on your OS. Another information source is the MySQL email archive. Please check all of the above before mailing us! And if you do mail us, you MUST use the /usr/bin/mysqlbug script! Starting MySQL...................................[FAILED] Anyone have this problem and know how to fix it??? Thanks! Jeff
