When recently using Fedora-Server-netinst-x86_64-Rawhide-20170103.n.0.iso for a new installation on a machine that already had encrypted LUKS partition (guarding LVs, actually), I was curious enough to have a look at the old, existing arrangement for reference. For this, it was handy I could enter the LUKS passphrase and unlock that. However, perhaps because there is no "lock again/close" button, I wasn't able to remove such once unlocked LUKS partition using standard "-" button, and the only straightforward solution for me was an annoying reboot, after which I started fresh installation from scratch. Please, handle this use case better, either with silent de-unlocking or by offering this option to the user explicitly. Version of anaconda (as well as of other involved components) is implied by the mentioned ISO (unfortunately there seems no mention of anaconda version in anaconda-ks.cfg file nor in the log files kept in /var/log/anaconda).
Found an exact version in /var/log/anaconda/{anaconda,journal}.log but it's rather nontrivial if you don't know which version format to expect. So, in this case it was anaconda 26.16-1. Btw. I filed [bug 1410595] to get this version easier to find for cases like this.
This bug appears to have been reported against 'rawhide' during the Fedora 26 development cycle. Changing version to '26'.
This message is a reminder that Fedora 26 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 26. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '26'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 26 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 26 changed to end-of-life (EOL) status on 2018-05-29. Fedora 26 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 bug. Thank you for reporting this bug and we are sorry it could not be fixed.
