Description lapseofreason0 2015-11-03 09:11:30 UTC
Description of problem:

When copying a Fedora live image to USB and enabling the encrypted persistent home option, the plymouth password entry screen is only shortly visible and then disappears. As a result, it is not possible to insert the LUKS passphrase and the boot hangs because it is waiting to decrypt the home partition.

Version-Release number of selected component (if applicable):

livecd-tools.x86_64                    1:22.2-1.fc22                    @updates
plymouth.x86_64                 0.8.9-9.2013.08.14.fc22                  @System
spin-kickstarts.noarch                   0.22.5-1.fc22                   @fedora
systemd.x86_64                       219-25.fc22                        @updates

How reproducible:

Every time.

Steps to Reproduce:
1. Download the Fedora live XFCE spin.
2. Copy the live image to USB with livecd-iso-to-disk, setting an encrypted home partition: livecd-iso-to-disk --extra-kernel-args "persistenthome=UUID=X-X-X-X" /path/to/iso/file.iso  /dev/sdbX
3. Reboot from USB and wait for passphrase dialog to appear.

Actual results:

The plymouth password entry screen briefly appears, but then disappears as other systemd services are started. As a result, boot hangs because it is waiting for passphrase, which cannot be inserted.

Expected results:

The pymouth password dialog shows up, the user inserts the password, and boot continues.

Additional info:

This happens also in basic graphics mode. I expect systemd to be responsible for this, because it continues loading other services that mask the boot prompt.

The script from which plymouth ask-for-password is called is in the file fedora-live-base.ks from the spin-kickstarts package.

Same on Fedora 23

Comment 2 Fedora End Of Life 2016-07-19 18:24:49 UTC
Fedora 22 changed to end-of-life (EOL) status on 2016-07-19. Fedora 22 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this

Thank you for reporting this bug and we are sorry it could not be fixed.

Please reopen this bug.  This problem continues in Fedora Workstation 31

Comment 4 Frederick Grose 2020-03-10 12:21:12 UTC
With Fedora 31 and most previous releases the password may be entered after the password: prompt appears on bootup.  The text mode startup continues to scroll, hiding the prompt, but it reappears once typing of a password continues.  The startup will continue to graphical completion.
