Extremely long boot time

[die.boer]

i suspect you've done an update while pursuing this problem , and the update fixed it ...
could you do a clean reboot and see if it's faster ?

[Snowhog]

I have, and it isn't.

My gut tells me that some processes is being called that is expecting something that doesn't exist and waits until it times out before the boot process proceeds. What that is I haven't a clue.

I haven't yet tried recreating the /boot/grub/grubenv file to eliminate it being corrupted or contains a persistent variable (or variables) that are causing this issue.

reboot again and immediately after logging in , run

systemctl show grub-common.service -p ExecMainStartTimestamp -p ExecMainExitTimestamp -p ExecMainPID -p InactiveExitTimestamp

journalctl -b -u grub-common.service -o short-monotonic --no-pager

and the ones from post #30

[Snowhog]

systemctl show grub-common.service -p ExecMainStartTimestamp -p ExecMainExitTimestamp -p
ExecMainPID -p InactiveExitTimestamp
InactiveExitTimestamp=Fri 2026-08-21 16:52:06 CDT
ExecMainStartTimestamp=
ExecMainExitTimestamp=

please run

sudo time grub-editenv /boot/grub/grubenv unset recordfail

and then immediately

sudo time grub-editenv /boot/grub/grubenv list

after that , also

systemctl cat grub-common.service
