Ubuntu 14.04 cannot find swap partition

[bwanaaa]

Laptop had Windows 7.
Installed Ubuntu 14.04
--no problem. grub2 gave appropriate choices
Added mate theme
--no problem.
Installed Kali Linux 1.1.0
--initially defaulted to grub boot menu but got back to grub 2 with grub customizer
Choosing to boot into windows or kali linux is ok.
Choosing to boot into Ubuntu show the mate boot screen with this dialog

I remember when I installed Kali that I specified the free space on the drive as ext4 and the pre-existing swap partition (from the pre-existing ubuntu 14.04 install) as swap. I saw no reason to have two swap partitions

How can I eliminate the error that occurs on the mate screen during ubuntu boot?

Please provide the output of:


sudo blkid

How are you installing the OSs after the first one? Are you manually partitioning and using the existing /swap or you are letting them do their own thing and create a new /swap for each install? The latter is not necessary nor desirable (same applies if you are creating a new /home partition for each install).

As you install each new OS, they install their grub to the same place, over the last grub, unless you are manually telling the install to put grub elsewhere. Kali was the last? We concentrate on what that is doing with grub and fstab.

PS: You can hit 's' to skip and continue without swapon to sort this out without an issue (if you have a decent amount of RAM).

windows 7 was preexisting on the laptop
the windows 7 partiton was shrunk and free space created
ubuntu was installed w default params
---everything was fine at this point
kali was installed using gui
- partitioning screens offerred option to change partitions
-i identified the preexisting swap partition and changed 'do not use' to 'swap'

kali will boot without any swap error dialog
ubuntu boots but presents swap error dialog

[sudodus]

Maybe Kali 'stole' the swap partition from Ubuntu. Please continue with some more output from terminal window commands.


cat /etc/fstab


sudo lsblk -fm


swapon -s

Edit: Do this while booted into Ubuntu if it is possible.

Thread moved to Ubuntu/Debian based.

This is starting to look more like a Kali related problem as it occurred after the Kali install. Might improve your chances if you post on their forum also. ;)

fstab is in the first post



sudo lsblk -fm

but if run the 'disks' app and 'play' the swap file


swapon -s

/dev/sda7: UUID="b391130e-4db4-4bd6-8804-0c604ae877ee" TYPE="swap"

swap's UUID has changed.

swapoff -a

edit and save fstab with the new UUID for swap

swapon -a

to check it

@Elfy

Yes! that fixed it. Thank you. I should have noticed the discrepancy when looking at the blkid compare to the stab but my eyes just glossed over the pile of hex.

Now I have to figure out why the boot process takes so long since I installed Kali. I'll post a new thread for that.
