I have problem upgrade cryptsetup to newer version.
OMV comes with 1.4.3, I added the backports repository but apt-get can't get the new version.
Manually download the package cryptsetup_1.6.4-4~bpo70+1_amd64.deb from debian package,
then do dpkg -i , it appears to be installed fine,
but cryptsetup --version still gives me 1.4.3?
