cryptsetup error ubuntu 11.04:

[audio1]

I just ran sudo apt-get update and updated all my packages which all seemed to update correctly. The problem I have is I got an error message in the last few lines of the terminal as below:

cryptsetup: WARNING: failed to detect canonical device of /dev/sda7
cryptsetup: WARNING: could not determine root device from /etc/fstab

Can someone help me solve this?

Thanks

post the contents of /etc/fstab and /etc/crypttab

Here is as you requested. I also tried sudo as it said permission denied.

x@x-Lenovo-V560:~$ /etc/fstab
bash: /etc/fstab: Permission denied
x@x-Lenovo-V560:~$ /etc/crypttab
bash: /etc/crypttab: Permission denied
x@x-Lenovo-V560:~$ sudo /etc/fstab
sudo: /etc/fstab: command not found
x@x-Lenovo-V560:~$ sudo /etc/crypttab
sudo: /etc/crypttab: command not found

Your help is truly appreciated. I will reply more quickly now I subscribed to this thread.

please navigate via nautilus to etc/fstab. no root needed to copy paste the content here.

To see the contents of a file you need to use a tool such as cat, less, gedit ...

cat /etc/fstab
less /etc/fstab
gedit /etc/fstab

Take your pick. As you are going to be editing the files, you will be using an editor - nano, vim , gedit, as root.

sudo -e /etc/fstab
gksu gedit /etc/fstab

Hi,

I'm still trying to solve this problem so any help appreciated.

Thankyou.

[bodhi.zazen]

"/dev/sda7" should read "/dev/mapper/root"

ls /dev/mapper

[audio1]

Thankyou.

My fstab file is now as follows:

# /etc/fstab: static file system information.
#
# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name
# devices that works even if disks are added and removed. See fstab(5).

/dev/mapper/cryptswap1 none swap sw 0 0

But I am getting the following error messages in the terminal and my system is still spitting out errors about unmounted disk on boot up.

x@x-Lenovo-V560:~$ sudo gedit /etc/fstab
[sudo] password for x:

(gedit:1972): Gtk-WARNING **: Attempting to store changes into `/root/.local/share/recently-used.xbel', but failed: Failed to create file '/root/.local/share/recently-used.xbel.9BYY0V': No such file or directory

(gedit:1972): Gtk-WARNING **: Attempting to set the permissions of `/root/.local/share/recently-used.xbel', but failed: No such file or directory

I did not fully understand the last line of your post ls /dev/mapper, was I supposed to do something with that?

Thanks

Is your root partition encrypted ?

If so , you need to list the proper device in fstab.

use the ls command to list the devices in /dev/mapper and correct your fstab syntax.

If you do not know, you need to tell us what partition is what and show the output of the ls command.

[audio1]

I do not know how to fix the syntax of fstab on my own - I'm a totally new Ubuntu user...sorry.

x@x-Lenovo-V560:~$ ls /dev/mapper
control cryptswap1

I have five partitions. I'm running a dual boot Windows 7 and Ubuntu.



The 4 Gb File System is the swap partition
The 210 Mb partition I'm not sure what that is - possibly windows
The 398Gb partition is for files
The Lenovo_Part partition is Lenovo recovery files I think
The File System which is 20Gb is for Ubuntu.

Is that what you needed?

[bodhi.zazen]

So the only thing your encrypted is swap ?

Post the output of


sudo fdisk -l

[bodhi.zazen]

OK, now tell us what those partitions are.

Specifically, which ones did you encrypt and which ones are for Ubuntu 11.04.

[audio1]

Hi,
I've been away. Still struggling with this issue.

1. I do not know which partitions I encrypted. If I did encrypt it would only because there was some prompt on the install. How can I tell which partition is encrypted?

2. I ran a partition program to try and mount all the disks. It has made my system more stable, but I still get a mounting error for ext4. The fstab file also shows some errors.

# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc nodev,noexec,nosuid 0 0
/dev/mapper/root ext4 errors=remount-ro 0 1
# swap was on /dev/sda8 during installation
#UUID=2f15bb05-f238-4e44-9f26-84138356cb4a none swap sw 0 0
/dev/mapper/cryptswap1 none swap sw 0 0
/dev/sda1 /media/sda1 ntfs nls=iso8859-1,ro,umask=000 0 0
/dev/sda2 /media/sda2 ntfs defaults 0 0
/dev/sda4 /media/sda4 ntfs defaults 0 0
/dev/sda5 /media/sda5 ntfs defaults 0 0
/dev/sda6 /media/sda6 swap defaults 0 0
/dev/sda7 /media/sda7 ext4 defaults 0 0

3. Here are the informations for my partitions:

sda1 210Mb NTFS Boot

sda2 370Gb NTFS File storage for Windows 7

sda4 15Gb
Lenovo OneKey Backup
Windows 7

sda5 5.4Gb NTFS Driver Backup for Windows 7


sda6 unknown swap unknown appears blank



sda7 45Gb ext4 Linux File System



I'm not sure what has happened to my 5Gb swap file for linux? How can I check this.

Thanks for assistance.

I met similar error message when I run "sudo update-initramfs -u -k all" command. I fixed it at last.
Before I tell how, unfortunately Ubuntu lovers suffer from lack of getting help in the forums. I meet many unanswered threads.
How I fixed it:
The error is printed by "/usr/share/initramfs-tools/hooks" as it was stated in this topic http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=671056
Main source of the error is corrupted swap partition linking.
First you need to get UUID of your swap partition. Just run blkid command. In my case error message was"cryptsetup: WARNING: failed to detect canonical device of /dev/sda5" so I noted down UUID of /dev/sda5. It was ede93e1b-0b68-468f-b6f6-ebf7a0c9d7ac
If you don't know how to create swap partition, take a look at this link http://askubuntu.com/questions/33697/adding-swap-partition-after-system-installation?lq=1
sudo gedit /etc/crypttab I deleted the related/dev/sda5 line in crypttab
sudo gedit /etc/fstab I opened fstab and added line UUID=ede93e1b-0b68-468f-b6f6-ebf7a0c9d7ac none swap sw 0 0


sudo gedit /etc/uswsusp.conf I opened uswsusp.conf file and changed resume device=/dev/sda5 to
resume device = UUID=ede93e1b-0b68-468f-b6f6-ebf7a0c9d7ac

finally I issued sudo update-initramfs -u -k all command and I got rid of that damn message. I hope it works for you too
I also benefitted from this topic http://techpatterns.com/forums/about1178.html
I hope it also fixes hibernating problem.
