I have an F13 installation on a VirtualBox VM. I learned that I need more than 512MB of RAM to install, so I added more RAM to the VM.
I attempted the "preupgrade" route. That failed. As I boot into F15 I get the following messages:
Starting /share failed, see 'systemctl status share.mount' for details.
Starting Mark the need to relabel after reboot aborted because a dependency failed.
Starting Relabel all filesystems, if necessary aborted because a dependency failed.
Starting /boot aborted because a dependency failed.
Starting File System Check on /dev/disk/by-uuid/.... aborted because a dependency failed.
Starting Getty on tty6 aborted because a dependency failed.
Welcome to emergency mode. Use 'systemctl default" or ^D to activate default mode.
Give root password for maintenance
(or type Control-D to continue):
If I log in with the root password, and type "systemctl default", I get:
Failed to issue method call: Transaction is destructive.
If I issue 'systemctl status share.mount', I get the following:
share.mount - /share
Active: failed since Fri, 01 Jul 2011....
Process: 538 ExecMount=/bin/mount /share (code=exited, status=1/FAILURE)
As I mentioned, I first attempted this with 'preupgrade'. I have the VM snapshotted, so I rolled back to F13, and this time I attempted to use the F15 installer, and got the same result as using 'preupgrade'. (But I failed much more quickly....because I had local media!)
So.....since I can roll back to F13 and try again, where can I start looking to solve this? Where can I look to see what dependency failed?
