how to set the RESUME variable (SOLVED)

[marcetm]

Hi all,

From about a month, every single time "apt upgrade" calls to "update-initramfs" I'm receiving this message:

W: initramfs-tools configuration sets RESUME=UUID=75a1abae-a571-45e0-8ba8-2af714d13b59
W: but no matching swap device is available.
I: The initramfs will attempt to resume from /dev/sda3
I: (UUID=010325a0-3867-4606-94da-51efff3e57ba)
I: Set the RESUME variable to override this.

Anyone knows how should I set the RESUME variable?

i'm not sure, but i'm guessing that this:

W: but no matching swap device is available.

might mean that your swap partition has changed UUID and you need t adjust that in fstab (and maybe elsewhere)
this typically happens when you install another OS alongside the first one.
so check your swaps actual UUID with 'sudo blkid', then compare to the one in /etc/fstab.

Look into /etc/initramfs-tools/initramfs.conf and /etc/initramfs-tools/conf.d/*

In my case it is set in /etc/initramfs-tools/conf.d/resume.

You might try finding the correct settings as stated in the above post by @debiman, correct the variable in the initramfs-tools config file, then regenerate initramfs by

Code: Select all

# update-initramfs -u -k all

I've edited the file

/etc/initramfs-tools/conf.d/resume

and changed the line (there's only one)

RESUME=UUID=75a1abae-a571-45e0-8ba8-2af714d13b59

by

RESUME=UUID=010325a0-3867-4606-94da-51efff3e57ba

as update-initramfs warned me in its message.

Now when I enter:

Code: Select all

# update-initramfs -u -k all

it doesn't complain anymore.

Thanks both for your help.
