The Fedora DVD upgrade is not very good to put it politely and gets steadily worse release by release. The installer is pretty robust, but the update stuff not so. A better bet is to make a backup and then carefully read the instructions on updating via yum. Follow all the steps listed in order. 16 to 17 is the most complicated one of the lot because of the changes to the file system layout. The yum update isn't "supported" but works far better than the DVD one. Given the state of the updater it's not clear what "supported" means in that context anyway 8( http://fedoraproject.org/wiki/Upgrading_Fedora_using_yum Alan -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
