Tried to install cryptsetup from wheezy-backports

[Cubytus]

Hi community,

in order to do a benchmark, I looked for the repository holding branch 1.6.x of cryptsetup, and found it in wheezy-backports. So I added the backports repo, imported the key, and installed 1.6.4 version from this repo, but now, every time I want to execute

Code: Select all

cryptsetup benchmark

(or any other command, for that matter), it outputs a rather unhelpful "Illegal instruction".

However, the exact same instructions worked on a Wheezy image…

How could I know where the issue is?

You have installed incompatible software.

Raspbian is not Debian. They do not work together. Raspbian is Debian for the Pi. Debian armhf doesn't support the Pi.

Please don't add any Debian sources to your sources.list, or download any software from a Debian repository (ok, some will work - anything that contains "_all" instead of "_armhf" in the filename), or you can wreck your system and need to do a fresh install.

Stick to the Raspbian repos or any that state they are compatible with Raspbian.

Or you can build the software yourself from the Debian source code.

I am making some progress here. Apparently there's a conflict between the newly-built cryptsetup 1.6.6 (from source, with checkinstall) and initramfs-tools:

(…)

Code: Select all

initramfs-tools (0.115~bpo70+1) breaks cryptsetup (<< 2:1.1.0-2.1) and is installed.

What I don't understand is the << sign, for me it means "lower than", and surely cryptsetup 1.6.6 is a greater version number than 1.1.0.

The 1.4.3 branch (and 1.6.4) of cryptsetup recommends a version >= 0.91 to be installed, but the cryptsetup 1.6.6 is broken by initramfs-tools 0.115.

Code: Select all

Package: cryptsetup
Version: 2:1.4.3-4
Architecture: armhf
Maintainer: Debian Cryptsetup Team <pkg-cryptsetup-devel@lists.alioth.debian.org>
Installed-Size: 295
Depends: libc6 (>= 2.13-28), debconf (>= 0.5) | debconf-2.0, dmsetup, cryptsetup-bin
Recommends: kbd, console-setup, initramfs-tools (>= 0.91) | linux-initramfs-tool, busybox | busybox-static

Should I assume I need a lower initramfs-tools version? In such a case what would be the lower version? I am expecting 0.109, but from

Code: Select all

aptitude versions initramfs-tools

I see there's only version 0.115 present? Or am I reading it the wrong way?

The 2: in front of the version number is an "Epoch number". It overrides the normal version numbers and means "this is later than anything that doesn't have at least a 2: in front".

So 2:1.1.0 is higher than just 1.6.6

Rebuild your cryptsetup with a 2: in front of the version number.

And how do I specify an epoch number when building? or configuring?

Hello there,

I am resurrecting an old topic to post that, even adding 2: in front of the version number yields another error:

I understand it tried to replace an existing manpage? How is it solved?

[rpdom]

Somehow you have got that manpage in your cryptsetup package that would normally be in the cryptsetup-bin package. Have you built it with the wrong name?

If you are certain that you want to go ahead you could try the --force-overwrite option when you install it. Then you will get a warning instead of an error and the installation will continue.

Should I change value 2 to specify cryptsetup-bin? Or some other one? Sorry but so far it's vague.
