Hello,

I am using the following the following tutorial to install dm-crypt and encrypt my hard drive:

I am using Ubuntu 8.10 Desktop Edition and when I do the following command:

Code:

modprobe aes

I get the following error:

Code:

WARNING: Error inserting padlock_aes (/lib/modules/2.6.27-7-generic/kernel/drivers/crypto/padlock-aes.ko): No such device
root@ubuntu:/home/ubuntu# modprobe dm-crypt

WARNING: Error inserting padlock_sha (/lib/modules/2.6.27-7-generic/kernel/drivers/crypto/padlock-sha.ko): No such device

Can anyone please help me?

As with so many other posts regarding problems with Ubuntu 8.10 your problem may be due to problems with the software. Look at post #2 at this link.

The guide to creating an encrypted file system on Ubuntu that you referenced as your instruction manual is written for Ubuntu 7.10. It may or may not be a good guide to performing that task with later versions of Ubuntu.

8.10 kernel may not have the modules for dm-crypt, or aes compiled into the kernel, so you may need to either rebuild the kernel and add support for dm-crypt and aes, or someone may have a kernel prebuilt with the support already you could download.

The instruction to use modprobe presumes that aes is not built into the kernel and must be loaded as a module.

Sorry didn't explain that properly, I ment that the modules may not have been built with the kernel, so you may need to rebuild the kernel and add support for them.
