Description of problem:
I did several updates without restarting the system using commandline calls to yum. Some of the updates installed new kernel versions and one of them removed currently used kernel package. After I did hibernate (susped to disk), I wasn't able to resume properly because there was no appropriate grub entry and I was forced to reboot to newest kernel with unclean filesystems.
There is no problem when there is one or two kernel upgrades since last reboot. It is the third upgrade that wipes current kernel files and grub entries without warning.
Note that it is a bit different from bug #1073514.
Version-Release number of selected component (if applicable):
All releases I know.
Steps to Reproduce:
1. Perform 3 upgrades of kernel during single uptime
2. Hibernate to disk
Resume fails because there's no proper kernel in the system.
Correct resume after hibernation (best).
Big red blinking warning that we're removing currently used kernel and a question "are you sure?" (suboptimal)
Prevent hibernation if it detects that there is no valid kernel to resume, e.g. was removed manually (optional, but this would add extra reliability to the system)
This can be easily fixed by preventing yum (or other package manager) from uninstalling currently used kernel. The only cost would be that temporarily there will be 4, not 3 kernel packages installed in the system. Of course if it is possible to limit to 3 versions but it is more complicated.
This message is a reminder that Fedora 20 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 20. 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bug reports from releases that are no longer maintained.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'
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 20 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 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 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.
