fedup F18 => F20 failed, can't find (encrypted) partitions

Tuesday, 31 December 2013

I just tried doing a fedup F18 to F20; the fedup itself worked fine
(apart from from a few warnings about GPG keys), but booting from the
'System Upgrade' grub entry failed early on, not being able to find
any of my system's filesystems. I suspect this is due to them being LUKS
encrypted (these filesystems were all created by the F18 anaconda
installer using the defaults and ticking 'Encrypt').

Under F18:

# rpm -q fedup
fedup-0.8.0-3.fc18.noarch

# hostname
robin

# df -h

When booting from the 'System Upgrade' boot entry, the screen clears, then
(in text mode) I get the following (this is hand-typed):

    [   4.797465] dracut-initqueue[426]: Failed to issue method call: Access denied
    [   OK  ] Started Show Plymouth Boot Screen
    [   OK  ] Reached target paths

It then sat doing nothing for a few minutes; I then pressed ESC, and the
following extra appeared:

    Generating "/run/initramfs/rdsosreport.txt"

    Entering emergency mode. Exit the shell to continue.
    Type "journalctl" to view system logs.
    You might want to save "/run/initramfs/rdsosreport.txt" to a USB stick or
    /boot
    after mounting them and attach it to a bug report.

The "/run/initramfs/rdsosreport.txt" file is 1400 lines long, so I haven't
attached it here; however, perusing it, this line stands out:

    [    4.797399] localhost systemd[1]: Failed to get security context on /etc/crypttab:
No such file or directory

Anyone got any ideas what I should do next?
