cannot shrink encrypted lvm partition
Binary package hint: partman-crypto
I'm installing gutsy dvd amd64 20071010.2 using ubiquity on a hard disk which I previously installed gutsy d-i i386 20071009.1 using whole disk encrypted LVM.
Now the ubiquity installer seems incapable of doing anything useful with my previous installation. I'm forced to destroy it completely. In principle it ought to be possible to resize it, given the appropriate passphrase etc.
