Description Pavel Raiskup 2024-12-01 18:45:39 UTC
Tested on c7i.xlarge, t3a.small.

From https://fedoraproject.org/wiki/Changes/HiddenGrubMenu
i did:

  sudo grub2-editenv - unset menu_auto_hide

Then:

  1. set GRUB_TIMEOUT=60 # in /etc/sysconfig/grub
  2. grub2-mkconfig > /boot/grub2/grub.cfg

Reboot... the grub menu is neither visible over "ssh console", nor
web-UI console.  See attachments.  If I ask EC2 to create screenshot,
it works (see attachments).

Reproducible: Always

Pavel, did this work before? In f-40 / grub2-2.06?

have you tried the same setting but under /etc/default/grub?

I haven't tried (ftr, we went from F39 to F41, skipped F40).

These are symlinks on F41:
$ ls -alh /etc/sysconfig/grub
lrwxrwxrwx. 1 root root 15 21. lis 01.00 /etc/sysconfig/grub -> ../default/grub

Feel free to find me on Matrix/Slack, I can try to allocate some
instance for you so you can experiment.

Comment 7 Leo Sandoval 2024-12-13 01:50:58 UTC
f41 is now based on grub-2.12, so lots of changes compared to f39 (based on grub-2.06)

One idea is to turn on debugging and see if we can get something from it: boot your system and at the cmdline type 'grub2-editenv - set debug=all', attach log please.

Comment 8 Adam Williamson 2025-12-02 01:48:59 UTC
This message is a reminder that Fedora Linux 41 is nearing its end of life.
Fedora will stop maintaining and issuing updates for Fedora Linux 41 on 2025-12-15.
It is Fedora's policy to close all bug reports from releases that are no longer
maintained.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
'version' of '41'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, change the 'version' 
to a later Fedora Linux version. Note that the version field may be hidden.
Click the "Show advanced fields" button if you do not see it.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora Linux 41 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 Linux, you are encouraged to change the 'version' to a later version
prior to this bug being closed.

Comment 9 Samyak Jain (RedHat) 2025-12-16 17:52:43 UTC
Fedora Linux 41 entered end-of-life (EOL) status on 2025-12-15.

Fedora Linux 41 is no longer maintained, which means that it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 Linux
please feel free to reopen this bug against that version. Note that the version
field may be hidden. Click the "Show advanced fields" button if you do not see
the version field.

If you are unable to reopen this bug, please file a new report against an
active release.

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