Thank you for the comments! I emailed the developer.
As the dislocker packages don't seem to have dependencies - that
aren't part of stable (buster),
I decided to create a so-called "FrankenDebian" (
https://wiki.debian.org/DontBreakDebian )
Here is hack:
I downloaded the (amd64) debs:
https://packages.debian.org/sid/amd64/dislocker/download
https://packages.debian.org/sid/amd64/libdislocker0.7/download
I then in the directory of the '.deb's did this:
# apt install ./dislocker_0.7.1-5_amd64.deb
# apt install ./libdislocker0.7_0.7.1-5_amd64.deb
If done properly - you should see this with 'dpkg --list'
# dpkg --list |grep dislocker
ii dislocker 0.7.1-5
amd64 read/write encrypted BitLocker volumes
ii libdislocker0.7 0.7.1-5
amd64 read/write encrypted BitLocker volumes
(shared library)
dislocker now works for me. :-)
If there is an easier more elegant (less hack-ish) way to do the
above... I am all ears.
